Description
本発明は、各種光学機器のシャッターや絞り部材、レンズのギャップ調整材などに使用可能な光学機器用遮光部材に関する。 The present invention relates to a light-shielding member for optical equipment that can be used for shutters and diaphragm members of various optical equipment, gap adjusting materials for lenses, and the like.
近年、高性能一眼レフカメラ、コンパクトカメラ、ビデオカメラ等の各種光学機器に対する小型化、軽量化の要求により、金属材料により形成されていた光学機器のシャッター、絞り部材、レンズのギャップ調整材がプラスチック材料へと代わりつつある。このようなプラスチック材料の遮光部材としては、カーボンブラック、滑剤、微粒子及びバインダー樹脂を含有する遮光膜をフィルム基材の上に形成した遮光フィルムが知られている(特許文献1、2)。 In recent years, due to demands for reducing the size and weight of various optical devices such as high-performance single-lens reflex cameras, compact cameras, and video cameras, the shutters, aperture members, and lens gap adjustment materials for optical devices that have been made of metal materials are made of plastic. It is changing to materials. As such a light shielding member made of a plastic material, a light shielding film in which a light shielding film containing carbon black, a lubricant, fine particles, and a binder resin is formed on a film substrate is known (Patent Documents 1 and 2).
しかしながら上述した従来の遮光部材では、遮光性、低光沢性(光写り込み防止性)、耐擦傷性のいずれかの性能に関して改善されたものはあったが、光学機器用遮光部材の遮光部材として、上記全ての性能を実用レベルで同時に満足するものは今まで無かった。 However, some of the conventional light-shielding members described above have been improved in terms of light-shielding properties, low glossiness (prevention of light reflection), and scratch resistance, but as light-shielding members for light-shielding members for optical devices. Until now, none of the above performances have been satisfied at the practical level at the same time.
例えば従来の技術例として、遮光性や遮光部材への光の写り込みが問題とされる場合、カーボンブラック等の黒色顔料を多量に添加して遮光性を十分なものとするか、フィラーを多量に添加して低光沢性を十分なものとしていたが、その場合には遮光塗膜中において、相対的にバインダー含有量が少なくなってしまい、耐擦傷性が劣ってしまったり、塗膜接着性が劣ってしまったりした。 For example, as a conventional technology example, when there is a problem with light shielding properties and reflection of light on the light shielding member, a large amount of black pigment such as carbon black is added to ensure sufficient light shielding properties, or a large amount of filler is used. In this case, the binder content is relatively low in the light-shielding coating, resulting in poor scratch resistance and coating adhesion. Was inferior.
本発明は、光学機器用遮光部材に使用される遮光部材として、基本的な性能である、遮光性は実用レベルを維持しながら、低光沢性(写り込み防止性)、耐擦傷性(加工取り扱い時や使用時の傷つき防止性)を同時に良好にすることを課題とする。 The present invention is a basic light-shielding member used as a light-shielding member for optical equipment, and has low glossiness (anti-reflection) and scratch resistance (processing handling) while maintaining a light-shielding property at a practical level. It is an object to simultaneously improve the scratch resistance during use and use.
本発明は、基材の少なくとも一方の面に、バインダー樹脂とフィラーとを含む樹脂溶液吸収層を形成し、前記樹脂溶液吸収層のバインダー樹脂は前記樹脂溶液吸収層を乾燥した状態で、遮光層塗布液に対して膨潤性あるいは溶解性を有するものであり、樹脂溶液吸収層を形成した後、前記樹脂溶液吸収層上に、バインダー樹脂、黒色微粒子及びフィラーを含む前記遮光層塗布液を塗布、乾燥し、遮光層を形成することを特徴とする光学機器用遮光部材である。 In the present invention, a resin solution absorption layer containing a binder resin and a filler is formed on at least one surface of a substrate, and the binder resin of the resin solution absorption layer is a light shielding layer in a state where the resin solution absorption layer is dried. It has swelling or solubility with respect to the coating solution, and after forming the resin solution absorption layer, the light shielding layer coating solution containing a binder resin, black fine particles and filler is applied on the resin solution absorption layer, It is a light-shielding member for optical equipment, which is dried to form a light-shielding layer.
また、前記樹脂溶液吸収層は、バインダー樹脂とフィラーとを含む樹脂溶液吸収層塗布液を塗布、乾燥することにより形成されてなり、前記樹脂溶液吸収層塗布液の固形分付着量が4〜40g/m2であることを特徴とする光学機器用遮光部材である。 The resin solution absorbing layer is formed by applying and drying a resin solution absorbing layer coating solution containing a binder resin and a filler, and the solid content adhesion amount of the resin solution absorbing layer coating solution is 4 to 40 g. It is a light-shielding member for optical equipment, characterized by being / m 2 .
また、前記遮光層塗布液の固形分付着量が2.5〜20g/m2であることを特徴とする光学機器用遮光部材である。 The light shielding member for optical equipment is characterized in that the solid content of the light shielding layer coating solution is 2.5 to 20 g / m 2 .
本発明の遮光部材は、上述の様な手段を取ることにより、光学機器用遮光部材として基本的な性能である遮光性は実用レベルを維持しながら、低光沢性(写り込み防止性)、耐擦傷性(加工取り扱い時や使用時の傷つき防止性)を同時に良好にすることができる。 The light-shielding member of the present invention adopts the above-described means, so that the light-shielding property, which is a basic performance as a light-shielding member for optical equipment, is maintained at a practical level, while having low glossiness (anti-reflection property), resistance to light. At the same time, the scratch resistance (prevention of scratches during processing and use) can be improved.
更に、本発明の遮光部材は、前記樹脂溶液吸収層上に前記遮光層を塗布により積層することによって簡易的に製造することが可能である。 Furthermore, the light shielding member of the present invention can be easily manufactured by laminating the light shielding layer on the resin solution absorbing layer by coating.
以下、本発明の光学機器用遮光部材(以下、「遮光部材」という場合もある)の実施の形態ついて説明する。 Hereinafter, an embodiment of a light shielding member for an optical device according to the present invention (hereinafter sometimes referred to as “light shielding member”) will be described.
本発明は、基材の少なくとも一方の面に、バインダー樹脂とフィラーとを含む樹脂溶液吸収層を形成し、前記樹脂溶液吸収層のバインダー樹脂は前記樹脂溶液吸収層を乾燥した状態で、遮光層塗布液に対して膨潤性あるいは溶解性を有するものであり、樹脂溶液吸収層を形成した後、前記樹脂溶液吸収層上に、バインダー樹脂、黒色微粒子及びフィラーを含む前記遮光層塗布液を塗布、乾燥し、遮光層を形成することを特徴とする光学機器用遮光部材である。 In the present invention, a resin solution absorption layer containing a binder resin and a filler is formed on at least one surface of a substrate, and the binder resin of the resin solution absorption layer is a light shielding layer in a state where the resin solution absorption layer is dried. It has swelling or solubility with respect to the coating solution, and after forming the resin solution absorption layer, the light shielding layer coating solution containing a binder resin, black fine particles and filler is applied on the resin solution absorption layer, It is a light-shielding member for optical equipment, which is dried to form a light-shielding layer.
基材としては、ポリエステルフィルム、ポリカーボネートフィルム、ポリイミドフィルム、ポリスルホンフィルム、ポリフェニレンスルフィドフィルム、アクリルフィルム、セルロースフィルム、ポリ塩化ビニルフィルム、ポリエチレンフィルム、ポリプロピレンフィルム、ポリスチレンフィルム、フッ素樹脂系フィルム等の合成樹脂フィルムが挙げられ、中でもポリエステルフィルムが好適に用いることができ、延伸加工、特に二軸延伸加工されたポリエチレンテレフタレートフィルム、ポリエチレンナフタレートフィルムが機械的強度、寸法安定性に優れる点で好ましい。また耐熱用途での使用には、ポリイミドフィルムを用いることもできる。 Synthetic resin films such as polyester film, polycarbonate film, polyimide film, polysulfone film, polyphenylene sulfide film, acrylic film, cellulose film, polyvinyl chloride film, polyethylene film, polypropylene film, polystyrene film, fluororesin film Among them, a polyester film can be suitably used, and a polyethylene terephthalate film and a polyethylene naphthalate film subjected to stretching processing, particularly biaxial stretching processing are preferable from the viewpoint of excellent mechanical strength and dimensional stability. Moreover, a polyimide film can also be used for use in a heat resistant application.
更に、基材として、透明なものはもちろん、発泡ポリエステルフィルムや、着色顔料等を含有させた合成樹脂フィルムを使用することもできる。この場合、上述の基材は、用途により適切なものを選択することができる。例えば、遮光部材として使用する際に、部材断面の合成樹脂フィルム部分においてレンズ等で集光された光が反射し悪影響を及ぼすため、高い遮光性が必要な場合には、黒色に着色された顔料が含有された合成樹脂フィルムを使用することができる。 Furthermore, as a base material, a transparent resin, a foamed polyester film, a synthetic resin film containing a color pigment, or the like can be used. In this case, an appropriate base material can be selected depending on the application. For example, when used as a light-shielding member, the light collected by the lens etc. in the synthetic resin film portion of the member cross section is reflected and adversely affected. A synthetic resin film containing can be used.
また、基材自体に遮光性があり軽量で剛性があることから、薄膜の金属板を用いてもよい。 Further, a thin metal plate may be used because the base material itself is light-shielding, lightweight and rigid.
基材の厚みとしては用途により異なり、例えば、遮光部材の軽量化重視の用途では比較的薄いものが選択され、強度・剛性重視の用途では比較的厚いものが選択されるが、一般的には6〜250μmとすることが好ましい。 The thickness of the base material varies depending on the application.For example, a relatively thin material is selected for an application that emphasizes weight reduction of a light shielding member, and a relatively thick material is selected for an application that emphasizes strength and rigidity. It is preferable to set it as 6-250 micrometers.
また、基材上に形成される樹脂溶液吸収層との接着性を向上させる観点から、基材上に、必要に応じてアンカー処理、プラズマ処理、EB処理あるいはコロナ処理を行うこともできる。 Moreover, from a viewpoint of improving adhesiveness with the resin solution absorption layer formed on a base material, an anchor process, a plasma process, EB process, or a corona process can also be performed on a base material as needed.
塗布により樹脂溶液吸収層を形成する場合には、まず合成樹脂フィルムからなる基材上に、バインダー樹脂とフィラーとを溶媒により混合させた樹脂溶液吸収層塗布液から形成される樹脂溶液吸収層を設ける。 When a resin solution absorption layer is formed by coating, first, a resin solution absorption layer formed from a resin solution absorption layer coating solution in which a binder resin and a filler are mixed with a solvent on a substrate made of a synthetic resin film. Provide.
本発明における樹脂溶液吸収層のバインダー樹脂としては、アルブミン、ゼラチン、カゼイン、でんぷん、アラビアゴムなどの天然樹脂、カルボキシメチルセルロース樹脂、ヒドロキシエチルセルロース樹脂、ポリビニルアルコール樹脂、ポリビニルピロリドン樹脂、ポリビニルブチラール樹脂、ポリビニルアセタール樹脂、ポリフェニルアセトアセタール樹脂、ポリビニルフォルマール樹脂、塩化ビニル・酢酸ビニル共重合樹脂、塩化ビニル・酢酸ビニル・ビニルアルコール三元共重合樹脂、アクリル樹脂、ポリエステル樹脂、ポリウレタン樹脂、エポキシ樹脂、ボリアミド樹脂、ポリアクリルアミド樹脂、アルキド樹脂、アクリルポリオール樹脂、ポリエステルポリオール樹脂、エポキシポリオール樹脂等が用いられ、これらの一種あるいは二種類以上を混合して使用しても良い。また、これらのバインダー樹脂に、(ポリ)イソシアネート化合物、メラミン類、アミン類、イミダゾール類などの硬化剤を合せて使用しても良い。これらのバインダー樹脂の一種あるいは二種以上を混合して使用するか、あるいはこれらのバインダー樹脂と硬化剤とを組み合わせて、硬化の程度を調整することにより、樹脂溶液吸収層の膨潤性あるいは溶解性を調整できる。 As the binder resin of the resin solution absorption layer in the present invention, natural resins such as albumin, gelatin, casein, starch, gum arabic, carboxymethyl cellulose resin, hydroxyethyl cellulose resin, polyvinyl alcohol resin, polyvinyl pyrrolidone resin, polyvinyl butyral resin, polyvinyl acetal Resin, polyphenylacetoacetal resin, polyvinyl formal resin, vinyl chloride / vinyl acetate copolymer resin, vinyl chloride / vinyl acetate / vinyl alcohol terpolymer resin, acrylic resin, polyester resin, polyurethane resin, epoxy resin, polyamide resin , Polyacrylamide resin, alkyd resin, acrylic polyol resin, polyester polyol resin, epoxy polyol resin, etc. are used. It may be used as a mixture of two or more types. These binder resins may be used in combination with a curing agent such as (poly) isocyanate compounds, melamines, amines, and imidazoles. By using one or a combination of two or more of these binder resins, or by combining these binder resins and a curing agent to adjust the degree of curing, the swellability or solubility of the resin solution absorption layer Can be adjusted.
本発明において、樹脂溶液吸収層とは、樹脂溶液吸収層に含有されるバインダー樹脂が、その上に積層する遮光層塗布液の溶媒により膨潤あるいは溶解し、樹脂溶液吸収層に遮光層塗布液の樹脂溶液分(溶媒分とバインダー分)が吸収される性質を有する層である。 In the present invention, the resin solution absorption layer means that the binder resin contained in the resin solution absorption layer is swollen or dissolved by the solvent of the light shielding layer coating solution laminated thereon, and the light shielding layer coating solution is formed in the resin solution absorption layer. It is a layer having the property of absorbing the resin solution component (solvent component and binder component).
従って、前記樹脂溶液吸収層に用いられるバインダー樹脂と、遮光層塗布液の溶媒とは、溶解度パラメーター(SP値)が近いものを選択して、樹脂溶液吸収層の膨潤性あるいは溶解性を調節することが好ましい。 Accordingly, the binder resin used in the resin solution absorption layer and the solvent of the light shielding layer coating solution are selected so that the solubility parameter (SP value) is close, and the swelling or solubility of the resin solution absorption layer is adjusted. It is preferable.
本発明において、樹脂溶液吸収層に遮光層塗布液を積層塗布、乾燥した時の塗膜状態としては、上述のように、樹脂溶液吸収層が一旦膨潤あるいは溶解した後、下層(樹脂溶液吸収層)と塗布された上層(遮光層)との界面は融合したまま成膜されると考えられる。 In the present invention, the coating state when the light-shielding layer coating solution is laminated and applied to the resin solution absorption layer and dried is as described above, after the resin solution absorption layer is once swollen or dissolved, then the lower layer (resin solution absorption layer) ) And the applied upper layer (light-shielding layer) is considered to be formed while being fused.
前述のような樹脂溶液吸収層上に遮光層塗布液を積層塗布した時に、本発明の効果が得られる理由は定かではないが、積層する遮光層塗布液の溶媒のSP値が樹脂溶液吸収層のバインダー樹脂のSP値と近い値の場合、樹脂溶液吸収層が膨潤あるいは溶解し、遮光層塗布液の樹脂溶液分(溶媒分とバインダー分)の一部を樹脂溶液吸収層が吸収することによると考えられる。 The reason why the effect of the present invention is obtained when the light-shielding layer coating solution is laminated and applied on the resin solution absorbing layer as described above is not clear, but the SP value of the solvent of the light-shielding layer coating solution to be laminated is the resin solution absorbing layer. When the SP value of the binder resin is close to the SP value, the resin solution absorption layer swells or dissolves, and the resin solution absorption layer absorbs part of the resin solution (solvent and binder) of the light shielding layer coating solution. it is conceivable that.
そして、遮光層塗布液の樹脂溶液分の一部が下層に吸収されると、乾燥成膜される遮光層の少なくとも上部(表面側)はフィラー分と黒色微粒子分が多くなり、遮光層塗布液の樹脂溶液分が吸収され難い耐溶剤性のある基材に積層する時よりも、低光沢性の効果が顕著に得られると考えられる。 Then, when a part of the resin solution portion of the light shielding layer coating solution is absorbed by the lower layer, at least the upper part (surface side) of the light shielding layer to be dry-formed increases the amount of filler and black fine particles. It is considered that the effect of low gloss is remarkably obtained as compared with the case of laminating on a solvent-resistant base material in which the resin solution is hardly absorbed.
また、遮光層塗布液の樹脂溶液分が下層(樹脂溶液吸収層)に吸収される時に、遮光層塗布液中の樹脂溶液分の全てが樹脂溶液吸収層に吸収されるわけではなく、遮光層塗膜中のフィラー分と黒色微粒子を保持できる程度には樹脂溶液分が遮光層中に残ると同時に、樹脂溶液吸収層と遮光層との界面付近では、膨潤あるいは溶解した樹脂溶液吸収層のバインダーと、遮光層のバインダーとが融合されて接着性が良好になり、更に膨潤あるいは溶解した樹脂溶液吸収層のバインダーが遮光層中のフィラー分と黒色微粒子を保持するように寄与する為に耐擦傷性も良好になっていると考えられる。 Further, when the resin solution content of the light shielding layer coating solution is absorbed by the lower layer (resin solution absorption layer), not all of the resin solution content in the light shielding layer coating solution is absorbed by the resin solution absorption layer. The resin solution remains in the light-shielding layer to the extent that it can retain the filler and black fine particles in the coating film, and at the same time, the binder of the resin solution absorption layer that swells or dissolves near the interface between the resin solution absorption layer and the light-shielding layer. Since the binder of the light shielding layer is fused and the adhesiveness is improved, the binder of the resin solution absorption layer which has been swollen or dissolved further contributes to retain the filler content and black fine particles in the light shielding layer. It is thought that the property is also good.
更に本発明の積層構造では、上述の低光沢性と耐擦傷性の向上以外に、遮光層塗布液に含有させる黒色微粒子をカーボンブラックとした場合には、その遮光層塗布液のみを耐溶剤性のある合成樹脂フィルム基材に直接単層のみ塗布、乾燥した場合よりも帯電防止性に優れた遮光部材が得られた。この時の帯電防止性が向上する理由は定かではないが、遮光層塗布液の樹脂溶液分(溶媒およびバインダー成分)が樹脂溶液吸収層に吸収されると、必然的に塗膜の上部はカーボンブラックおよびフィラー成分が多く露出し易くなり(バインダー成分が少なくなり)帯電防止性が良好になると考えられる。 Furthermore, in the laminated structure of the present invention, in addition to the above-described improvement in low gloss and scratch resistance, when the black fine particles to be contained in the light shielding layer coating liquid are carbon black, only the light shielding layer coating liquid is solvent resistant. As a result, a light-shielding member having better antistatic properties than that obtained by applying and drying only a single layer directly on a synthetic resin film substrate having a certain thickness was obtained. The reason why the antistatic property is improved at this time is not clear, but if the resin solution component (solvent and binder component) of the light shielding layer coating solution is absorbed by the resin solution absorbing layer, the upper part of the coating film is necessarily carbon. It is considered that a large amount of black and filler components are easily exposed (the binder component is reduced) and the antistatic property is improved.
本発明の樹脂溶液吸収層の膨潤性は、下層(樹脂溶液吸収層)が溶解してしまう程度でも本発明の効果は得られるが、下層が完全に溶解してしまう場合には、上層(遮光層)と下層とのバインダー樹脂の相溶性が悪い場合は塗布ムラが発生する危険性があるので、下層の表面が膨潤する程度の方が好ましい。 The swellability of the resin solution absorption layer of the present invention can be obtained even if the lower layer (resin solution absorption layer) is dissolved, but if the lower layer is completely dissolved, the upper layer (light shielding When the compatibility of the binder resin between the layer) and the lower layer is poor, there is a risk of uneven coating, so that the surface of the lower layer is preferably swollen.
次に、本発明の実施形態において、樹脂溶液吸収層のバインダー樹脂にはフィラーを含ませる。 Next, in the embodiment of the present invention, a filler is included in the binder resin of the resin solution absorption layer.
樹脂溶液吸収層にフィラーを含有させることにより、遮光層塗布液の溶媒分あるいは樹脂溶液分の、樹脂溶液吸収層への吸収性、膨潤性が向上する。 By containing a filler in the resin solution absorption layer, the absorbability and swelling property of the solvent solution or the resin solution of the light shielding layer coating solution into the resin solution absorption layer are improved.
樹脂溶液吸収層にフィラーを含ませた場合の、樹脂溶液吸収層の吸収性、膨潤性が向上する理由は、フィラーを含有させることにより、樹脂溶液吸収層のバインダー樹脂成分とフィラーとの間に微小な隙間が生じ、毛細管現象により溶媒等が浸透し易くなり、樹脂溶液吸収層が膨潤し易くなると考えられる。 The reason why the resin solution absorption layer absorbs and swells when the resin solution absorption layer contains a filler is that the filler is contained between the binder resin component and the filler in the resin solution absorption layer. It is considered that a minute gap is generated, and the solvent or the like is easily penetrated by a capillary phenomenon, and the resin solution absorption layer is easily swelled.
樹脂溶液吸収層に含ませることができるフィラーとしては、不定形、球状、針状、板状の形状にかかわらず、シリカ、アルミナ、珪酸アルミニウム、クレー、スメクタイト、炭酸カルシウム、硫酸カルシウム、硫酸バリウム、酸化チタン、合成ゼオライト等の無機系フィラーの他、架橋アクリル樹脂ビーズ、ウレタン樹脂ビーズ、架橋スチレン樹脂ビーズ、ベンゾグアナミン樹脂ビーズ、シリコン樹脂ビーズ、フッ素樹脂ビーズ等の有機系フィラーが挙げられ、いわゆる体質顔料のように無色であっても、着色されていても良く、また、表面が導電剤で被覆されていても良く、これらを単独であるいは2種以上を混合して使用することができる。これらのフィラーの中でも、特にシリカが好適に用いることができる。 Fillers that can be included in the resin solution absorption layer include silica, alumina, aluminum silicate, clay, smectite, calcium carbonate, calcium sulfate, barium sulfate, regardless of the shape of amorphous, spherical, needle, or plate. In addition to inorganic fillers such as titanium oxide and synthetic zeolite, organic fillers such as crosslinked acrylic resin beads, urethane resin beads, crosslinked styrene resin beads, benzoguanamine resin beads, silicon resin beads, and fluororesin beads can be mentioned. These may be colorless or colored, and the surface may be coated with a conductive agent, and these can be used alone or in admixture of two or more. Among these fillers, silica can be particularly preferably used.
樹脂溶液吸収層に含ませることができるフィラーの平均粒子径としては、好ましくは1〜12μm、より好ましくは2〜10μm、更に好ましくは3〜8μmが好適に用いることができる。 As an average particle diameter of the filler which can be contained in a resin solution absorption layer, Preferably it is 1-12 micrometers, More preferably, it is 2-10 micrometers, More preferably, 3-8 micrometers can be used suitably.
フィラーの平均粒子径を1μm以上とすることにより、バインダー樹脂とフィラーとの隙間における毛細管現象による樹脂溶液吸収性、膨潤性を十分なものとすることができ、また、平均粒子径を12μm以下とすることにより、樹脂溶液吸収層表面が粗れ過ぎて毛細管現象による樹脂溶液吸収性、膨潤性が過多になることを防止できる。 By setting the average particle diameter of the filler to 1 μm or more, the resin solution absorbability and swelling property due to the capillary phenomenon in the gap between the binder resin and the filler can be made sufficient, and the average particle diameter is set to 12 μm or less. By doing so, it can be prevented that the surface of the resin solution absorption layer becomes too rough and the resin solution absorbability and swelling due to capillary action become excessive.
なお、本発明でいう平均粒子径とは、レーザー回折式粒度分布測定装置(例えば、島津製作所社:SALD−7000など)で測定されるメディアン径(D50)を指す。黒色微粒子の他、滑剤などが添加される場合も同様である。 In addition, the average particle diameter as used in the field of this invention refers to the median diameter (D50) measured with a laser diffraction type particle size distribution measuring apparatus (for example, Shimadzu Corporation SALD-7000). The same applies when a lubricant or the like is added in addition to the black fine particles.
前記樹脂溶液吸収層に含ませることができるフィラーの含有量の下限としては、樹脂溶液吸収層中、好ましくは5重量%以上、より好ましくは10重量%以上、更に好ましくは15重量%以上であり、5重量%以上とすることにより、樹脂溶液吸収性および膨潤性が良好になり本発明の効果が得やすくなる。フィラーの含有量の上限としては、樹脂溶液吸収層中、好ましくは50重量%以下、より好ましくは45重量%以下、更に好ましくは40重量%以下であり、50重量%以下とすることにより、上記樹脂溶液吸収性および膨潤性が過多になることを防止しやすくなると同時に、樹脂溶液吸収層と合成樹脂フィルムからなる基材との接着性が劣ることを防止しやすい。 The lower limit of the content of the filler that can be included in the resin solution absorption layer is preferably 5% by weight or more, more preferably 10% by weight or more, and further preferably 15% by weight or more in the resin solution absorption layer. By setting it as 5 weight% or more, resin solution absorptivity and swelling property become favorable and it becomes easy to acquire the effect of this invention. The upper limit of the filler content is preferably 50% by weight or less, more preferably 45% by weight or less, still more preferably 40% by weight or less, and 50% by weight or less in the resin solution absorption layer. It becomes easy to prevent the resin solution absorbability and the swelling property from becoming excessive, and at the same time, it is easy to prevent the adhesiveness between the resin solution absorbing layer and the substrate made of the synthetic resin film from being deteriorated.
本発明で用いられる、樹脂溶液吸収層塗布液あるいは遮光層塗布液の溶媒とは、塗布液が溶解系である時の溶剤を指す場合と、塗布液が分散系である時の分散媒を指す場合の両方を含み、水、アルコール系、エステル系、芳香族炭化水素系、脂肪族炭化水素系、ケトン系、エーテル系、グリコール系等の汎用溶媒を用いることができ、これらの一種か二種以上を混合して用いてもよい。 The solvent of the resin solution absorbing layer coating solution or the light shielding layer coating solution used in the present invention refers to a solvent when the coating solution is a dissolution system and a dispersion medium when the coating solution is a dispersion system. In general, water, alcohol-based, ester-based, aromatic hydrocarbon-based, aliphatic hydrocarbon-based, ketone-based, ether-based, glycol-based and other general-purpose solvents can be used. You may mix and use the above.
例えば本発明における塗布液を溶解系塗布液で使用する場合、その塗布液の溶媒はその塗布液のバインダーを溶解するものであれば前記のような溶媒を適宜選択できる。 For example, when the coating liquid in the present invention is used as a dissolution system coating liquid, the solvent as described above can be appropriately selected as long as it dissolves the binder of the coating liquid.
また、遮光層塗布液の溶媒に関しては、遮光層塗布液の溶媒のSP値と、下層である樹脂溶液吸収層のバインダー樹脂のSP値との差の絶対値が5以内であることが好ましく、より好ましくは4以内、更に好ましくは3以内が好ましい。両者のSP値の差の絶対値を5以内にすることにより、遮光層塗布液を樹脂溶液吸収層上に積層塗布した時に、樹脂溶液液吸収層のバインダー樹脂が適度に膨潤あるいは溶解され、本発明の効果が得られやすい。 In addition, regarding the solvent of the light shielding layer coating solution, the absolute value of the difference between the SP value of the solvent of the light shielding layer coating solution and the SP value of the binder resin of the lower resin solution absorbing layer is preferably within 5; More preferably, it is within 4, more preferably within 3. By making the absolute value of the difference between the SP values within 5 when the light-shielding layer coating solution is laminated on the resin solution absorbing layer, the binder resin in the resin solution absorbing layer is appropriately swollen or dissolved. The effect of the invention is easily obtained.
その他、溶媒の選択に関しては、乾燥中に発生するクレーター現象やはじき現象を調整するために、沸点や蒸発速度が適切な溶媒を選択することが好ましい。 In addition, regarding the selection of the solvent, it is preferable to select a solvent having an appropriate boiling point and evaporation rate in order to adjust the crater phenomenon and the repelling phenomenon that occur during drying.
樹脂溶液吸収層塗布液の固形分付着量(片面あたり)としては、4〜40g/m2が好ましく、より好ましくは5〜35g/m2、更に好ましくは6〜30g/m2であり、固形分付着量を4g/m2を以上にすることにより、遮光層塗布液を積層する時の溶媒で樹脂溶液吸収層が溶解し過ぎることによる塗布ムラを防止しやすくなり、また塗膜全体がほとんど遮光層のみの単層構造になってしまうことを防止しやすくなり、本発明の効果が得られやすい。また、固形分付着量を40g/m2以下とすることにより、樹脂溶液吸収層自体を厚膜塗布することによる、ゆず肌、ピンホール、クレーター等の塗工上の外観不良を防止しやすくできるとともに、製造速度低下による製造コスト上昇を抑えられる。 Solid adhered amount of the resin solution absorbing layer coating solution as (per side) is preferably 4~40g / m 2, more preferably 5~35g / m 2, more preferably from 6~30g / m 2, a solid By setting the amount of adhesion to 4 g / m 2 or more, it becomes easy to prevent coating unevenness due to excessive dissolution of the resin solution absorption layer with the solvent when laminating the light shielding layer coating solution, and almost the entire coating film It becomes easy to prevent a single-layer structure having only a light-shielding layer, and the effects of the present invention are easily obtained. In addition, by setting the solid content adhesion amount to 40 g / m 2 or less, it is possible to easily prevent appearance defects on coating such as yuzu skin, pinholes, craters, etc., due to thick coating of the resin solution absorption layer itself. In addition, an increase in manufacturing cost due to a decrease in manufacturing speed can be suppressed.
本発明の遮光部材の塗膜構造は、合成樹脂フィルム基材上の樹脂溶液吸収層および遮光層を合算した塗膜全体において、塗膜全体の上部(表面側)と塗膜全体の下部(基材と接する側)とで、黒色微粒子の存在量は塗膜全体の上部の方が多くなっていると考えられる。従って、塗膜全体の下部には、黒色微粒子が少ないかあるいは存在しないかのどちらかであり、合成樹脂フィルム基材と樹脂溶液吸収層との接着性は良好となる。 The coating film structure of the light-shielding member of the present invention is such that the entire coating film including the resin solution absorption layer and the light-shielding layer on the synthetic resin film substrate is an upper part (front side) of the entire coating film and a lower part (base) of the entire coating film. It is considered that the amount of black fine particles present in the upper part of the entire coating film increases on the side in contact with the material. Therefore, there are few or no black fine particles in the lower part of the whole coating film, and the adhesiveness between the synthetic resin film substrate and the resin solution absorption layer is good.
上述のような本発明の塗膜全体の構造は、塗膜の断面解析により、黒色微粒子の分布の違いで表せられる。 The structure of the whole coating film of the present invention as described above can be represented by the difference in the distribution of black fine particles by cross-sectional analysis of the coating film.
塗膜断面の解析方法としては、断面のESCA分析(X線光電子分光分析)によるか、合成樹脂フィルム基材に塗膜が担持されたままミクロトーム等で断面切断し、顕微鏡による黒色微粒子の濃度差を観察する方法が考えられる。 As a method for analyzing the cross section of the coating film, the cross section is cut by ESCA analysis (X-ray photoelectron spectroscopic analysis) of the cross section or with a microtome or the like while the coating film is supported on the synthetic resin film substrate, and the concentration difference of the black fine particles by a microscope The method of observing can be considered.
次に、樹脂溶液吸収層の上には、遮光層が積層される。遮光層は、バインダー樹脂、黒色微粒子、フィラーを含む遮光層塗布液から形成される。 Next, a light shielding layer is laminated on the resin solution absorption layer. The light shielding layer is formed from a light shielding layer coating solution containing a binder resin, black fine particles, and a filler.
遮光層に用いられるバインダー樹脂としては、ポリ(メタ)アクリル酸系樹脂、ポリエステル樹脂、ポリエステルポリオール樹脂、ポリ酢酸ビニル樹脂、ポリ塩化ビニル樹脂、ポリビニルブチラール樹脂、セルロース系樹脂、ポリスチレン/ポリブタジエン樹脂、ポリウレタン樹脂、アルキド樹脂、ポリアミド樹脂、ポリイミド樹脂、ポリアミドイミド樹脂、アクリル樹脂、アクリルポリオール樹脂、不飽和ポリエステル樹脂、エポキシエステル樹脂、エポキシ樹脂、エポキシポリオール樹脂、エポキシアクリレート系樹脂、ウレタンアクリレート系樹脂、ポリエステルアクリレート系樹脂、ポリエーテルアクリレート系樹脂、フェノール系樹脂、メラミン系樹脂、尿素系樹脂、ジアリルフタレート系樹脂等の、熱可塑性樹脂または熱硬化性樹脂が挙げられる。熱硬化させて使用する場合は、イソシアネート化合物、イソシアネートプレポリマー、アミン類、イミダゾール等の硬化剤で硬化させて耐擦傷性等を良好にすることもでき、これら樹脂および硬化剤は、各々、1種又は2種以上を混合して用いることもできる。 Binder resins used in the light shielding layer include poly (meth) acrylic resin, polyester resin, polyester polyol resin, polyvinyl acetate resin, polyvinyl chloride resin, polyvinyl butyral resin, cellulose resin, polystyrene / polybutadiene resin, polyurethane Resin, alkyd resin, polyamide resin, polyimide resin, polyamideimide resin, acrylic resin, acrylic polyol resin, unsaturated polyester resin, epoxy ester resin, epoxy resin, epoxy polyol resin, epoxy acrylate resin, urethane acrylate resin, polyester acrylate Thermoplastic resins or thermosetting resins such as epoxy resins, polyether acrylate resins, phenol resins, melamine resins, urea resins, diallyl phthalate resins Butter, and the like. When heat-cured and used, it can be cured with a curing agent such as isocyanate compound, isocyanate prepolymer, amines, imidazole, etc. to improve the scratch resistance and the like. A seed or a mixture of two or more may be used.
遮光層に用いられるバインダー樹脂の含有量の下限としては、遮光層中、好ましくは10重量%以上、より好ましくは15重量%以上、更に好ましくは20重量%以上であり、 バインダー樹脂の含有量を10重量%以上とすることにより、黒色微粒子やフィラーを十分保持できて、これらが脱落することを防止しやすい。遮光層に用いられるバインダー樹脂の含有量の上限としては、遮光層中、好ましくは70重量%以下、より好ましくは65重量%以下、更に好ましくは60重量%以下であり、バインダー樹脂の含有量を70重量%以下とすることにより、黒色微粒子やフィラーの含有量が相対的に少なくなることによる遮光性不足や光沢性が高くなることを防止しやすい。 The lower limit of the content of the binder resin used in the light shielding layer is preferably 10% by weight or more, more preferably 15% by weight or more, and still more preferably 20% by weight or more in the light shielding layer. By setting it as 10 weight% or more, it can hold | maintain black microparticles | fine-particles and a filler enough, and it is easy to prevent that these fall off. The upper limit of the content of the binder resin used in the light shielding layer is preferably 70% by weight or less, more preferably 65% by weight or less, and still more preferably 60% by weight or less in the light shielding layer. By setting it to 70% by weight or less, it is easy to prevent insufficient light-shielding properties and high glossiness due to the relatively small content of black fine particles and filler.
次に、遮光層に含有される黒色微粒子は、バインダー樹脂を黒色に着色させ遮光性を付与させるためのものである。また、静電気による帯電を防止するために、導電剤あるいは帯電防止剤を適宜合わせて含有させることもできる。 Next, the black fine particles contained in the light shielding layer are for imparting light shielding properties by coloring the binder resin black. In addition, in order to prevent charging due to static electricity, a conductive agent or an antistatic agent can be appropriately contained.
黒色微粒子としては、例えばカーボンブラック、チタンブラック等があり、中でもカーボンブラックは、遮光性と帯電防止性との両特性が同時に付与できるので好適に用いられる。 Examples of the black fine particles include carbon black and titanium black. Among them, carbon black is preferably used because it can provide both light shielding properties and antistatic properties simultaneously.
遮光層に含有される黒色微粒子の平均粒子径としては、十分な遮光性を得るために1μm未満が好ましく、より好ましくは0.5μm以下である。 The average particle size of the black fine particles contained in the light shielding layer is preferably less than 1 μm, more preferably 0.5 μm or less in order to obtain sufficient light shielding properties.
遮光層に含有される黒色微粒子の含有量の下限としては、遮光層中、好ましくは5重量%以上、より好ましくは10重量%以上、更に好ましくは15重量%以上であり、黒色微粒子の含有量を5重量%以上とすることにより、遮光層の遮光性を十分なものとすることができる。遮光層に含有される黒色微粒子の含有量の上限としては、好ましくは25重量%以下、より好ましくは22重量%以下、更に好ましくは20重量%以下であり、黒色微粒子の含有量を25重量%以下とすることにより、遮光層中のバインダー樹脂やフィラーの含有量が相対的に少なくなることによる、遮光層の耐擦傷性不良、樹脂溶液吸収層との密着性不良あるいは光沢性が高くなることを防止できる。 The lower limit of the content of the black fine particles contained in the light shielding layer is preferably 5% by weight or more, more preferably 10% by weight or more, and further preferably 15% by weight or more in the light shielding layer. By making the amount 5% by weight or more, the light shielding property of the light shielding layer can be made sufficient. The upper limit of the content of black fine particles contained in the light shielding layer is preferably 25% by weight or less, more preferably 22% by weight or less, still more preferably 20% by weight or less, and the content of black fine particles is 25% by weight. By making the following, the content of the binder resin or filler in the light shielding layer is relatively reduced, resulting in poor scratch resistance of the light shielding layer, poor adhesion to the resin solution absorption layer, or high glossiness. Can be prevented.
次に、前記遮光層に含有されるフィラーとしては、シリカ、アルミナ、珪酸アルミニウム、クレー、スメクタイト、炭酸カルシウム、硫酸カルシウム等の無機系フィラーの他、架橋アクリル樹脂ビーズ、ウレタン樹脂ビーズ、架橋スチレン樹脂ビーズ、ベンゾグアナミン樹脂ビーズ、シリコン樹脂ビーズ、フッ素樹脂ビーズ等の有機系フィラーが挙げられ、いわゆる体質顔料のように無色であっても、着色されていても良く、また、表面が導電剤で被覆されていても良く、これらを単独であるいは2種以上を混合して使用しても良い。 Next, as the filler contained in the light shielding layer, in addition to inorganic fillers such as silica, alumina, aluminum silicate, clay, smectite, calcium carbonate, calcium sulfate, crosslinked acrylic resin beads, urethane resin beads, crosslinked styrene resin Examples include organic fillers such as beads, benzoguanamine resin beads, silicon resin beads, and fluororesin beads. They may be colorless or colored like so-called extender pigments, and the surface is coated with a conductive agent. These may be used alone or in admixture of two or more.
遮光層に含有されるフィラーは、上記のように、前述の樹脂溶液吸収層に含ませることができるフィラーと同様のものが使用できるが、それを添加する目的は樹脂溶液吸収層に添加する目的と異なり、表面に微細な凹凸を形成させることで入射光の反射を少なくし、表面の光沢度を低下させ、光学機器用遮光部材とした際の艶消し性を向上させるためのものである。 As described above, the filler contained in the light-shielding layer can be the same as the filler that can be included in the resin solution absorption layer described above, but the purpose of adding it is the purpose of adding it to the resin solution absorption layer. Unlike the above, by forming fine irregularities on the surface, the reflection of incident light is reduced, the glossiness of the surface is lowered, and the matteness when used as a light-shielding member for optical equipment is improved.
遮光層に含有されるフィラーの平均粒子径としては、やはり樹脂溶液吸収層に含有させる場合と同様であり、好ましくは1〜12μm、より好ましくは2〜10μm、更に好ましくは3〜8μmが好適に用いられる。1μm以上とすることにより、遮光部材に対して大きい角度で入射(フィルムに対して垂直入射を入射角0度とする)した光に対しても低光沢性を示すことができ、12μm以下とすることにより、フィラーが大き過ぎて塗膜から脱落し易くなることを防ぐことができる。 The average particle size of the filler contained in the light-shielding layer is the same as that in the case where it is contained in the resin solution absorption layer, preferably 1 to 12 μm, more preferably 2 to 10 μm, and further preferably 3 to 8 μm. Used. By setting the thickness to 1 μm or more, low gloss can be exhibited even for light incident at a large angle with respect to the light-shielding member (perpendicular incidence to the film is 0 degree), and the thickness is set to 12 μm or less. Thus, it is possible to prevent the filler from being too large and easily coming off from the coating film.
遮光層に含有されるフィラーの含有量の下限としては、遮光層中、好ましくは5重量%以上、より好ましくは10重量%以上、更に好ましくは15重量%以上であり、遮光層中、5重量%以上とすることにより、遮光層に微細な凹凸を形成させ、表面の光沢度を低下させることができる。遮光層に含有させるフィラーの含有量の上限としては、遮光層中、好ましくは50重量%以下、より好ましくは45重量%以下、更に好ましくは40重量%以下であり、遮光層中、50重量%以下とすることにより、遮光層中の黒色微粒子やバインダー樹脂の含有量が相対的に少なくなることによる、遮光性不足や樹脂溶液吸収層との密着性不良を防止できる。 The lower limit of the content of the filler contained in the light shielding layer is preferably 5% by weight or more, more preferably 10% by weight or more, still more preferably 15% by weight or more in the light shielding layer, and 5% by weight in the light shielding layer. By setting it as% or more, fine unevenness can be formed in the light shielding layer, and the glossiness of the surface can be lowered. The upper limit of the content of the filler contained in the light shielding layer is preferably 50% by weight or less, more preferably 45% by weight or less, still more preferably 40% by weight or less in the light shielding layer, and 50% by weight in the light shielding layer. By making it below, it is possible to prevent insufficient light shielding properties and poor adhesion with the resin solution absorption layer due to the relatively small content of black fine particles and binder resin in the light shielding layer.
遮光層の厚みに関しては、樹脂溶液吸収層に積層した場合は、界面が融合してしまうと判別し難く測定し難い。従って遮光層塗布液の固形分、比重およびウェット塗布量から算出される理論厚みで表わすか実際の付着量(g/m2)で表わすことが好ましい。 Regarding the thickness of the light shielding layer, when it is laminated on the resin solution absorption layer, it is difficult to determine and measure when the interface is fused. Accordingly, it is preferable to express the theoretical thickness calculated from the solid content, specific gravity, and wet coating amount of the light shielding layer coating solution, or the actual adhesion amount (g / m 2 ).
遮光層塗布液の固形分付着量(片面あたり)としては、2.5〜20g/m2が好ましく、より好ましくは3.5〜19g/m2、更に好ましくは4.5〜18g/m2である。固形分付着量を2.5g/m2以上とすることにより、樹脂溶液吸収層の膨潤性が不十分になることを防止でき、更に、遮光性も十分なものとすることができる。また、固形分付着量を20g/m2以下とすることにより、遮光層塗布液の樹脂溶液分が、下層に吸収されてなる本発明の効果を顕著なものとすることができる。つまり遮光層が厚すぎる場合には、樹脂溶液吸収層が膨潤あるいは溶解して吸収したとしても、遮光層塗膜への影響(本発明の効果)が少なくなってしまうと考えられる。 As solid content adhesion amount (per one side) of a light shielding layer coating liquid, 2.5-20 g / m < 2 > is preferable, More preferably, it is 3.5-19 g / m < 2 >, More preferably, 4.5-18 g / m < 2 >. It is. By setting the solid content adhesion amount to 2.5 g / m 2 or more, it is possible to prevent the swelling property of the resin solution absorption layer from being insufficient, and further, the light shielding property can be sufficient. Moreover, the effect of this invention by which the resin solution part of a light shielding layer coating liquid is absorbed into a lower layer can be made remarkable by making solid content adhesion amount 20 g / m < 2 > or less. That is, when the light shielding layer is too thick, even if the resin solution absorption layer swells or dissolves and absorbs, it is considered that the influence on the light shielding layer coating film (the effect of the present invention) is reduced.
本発明における樹脂溶液吸収層の固形分付着量と遮光層の固形分付着量との比〔(遮光層固形分付着量g/m2)/(樹脂溶液吸収層固形分付着量g/m2)〕は、好ましくは0.1〜2.0、より好ましくは0.2〜1.5、更に好ましくは0.3〜1.0程度であると本発明の効果が得られやすい。 Ratio of solid content adhesion amount of resin solution absorption layer and solid content adhesion amount of light shielding layer in the present invention [(light shielding layer solid content adhesion amount g / m 2 ) / (resin solution absorption layer solid content adhesion amount g / m 2] )] Is preferably 0.1 to 2.0, more preferably 0.2 to 1.5, and still more preferably about 0.3 to 1.0, whereby the effects of the present invention can be easily obtained.
本発明における樹脂溶液吸収層および遮光層の比重は、それらの層に使用される成分により異なるが、樹脂溶液吸収層ではおよそ0.9〜1.2の範囲であり、遮光層ではおよそ1.0〜1.3の範囲である。 The specific gravity of the resin solution absorption layer and the light shielding layer in the present invention varies depending on the components used in those layers, but is about 0.9 to 1.2 for the resin solution absorption layer, and about 1. for the light shielding layer. It is in the range of 0 to 1.3.
樹脂溶液吸収層および遮光層には、本発明の機能を損なわない限り、帯電防止剤、導電剤、硬化剤、滑剤、難燃剤、紫外線吸収剤、抗菌剤、防カビ剤、酸化防止剤、レベリング剤、流動調整剤、消泡剤、分散剤、分散助剤等の添加剤を含有させてもよい。 As long as the function of the present invention is not impaired, the resin solution absorbing layer and the light shielding layer are provided with an antistatic agent, a conductive agent, a curing agent, a lubricant, a flame retardant, an ultraviolet absorber, an antibacterial agent, an antifungal agent, an antioxidant, and leveling. You may contain additives, such as an agent, a flow regulator, an antifoamer, a dispersing agent, and a dispersion aid.
例えば、樹脂溶液吸収層あるいは遮光層に、粒子状の滑剤を添加する場合は、ステアリン酸カルシウム等の金属石鹸、タルク(滑石)、二硫化モリブデン等の無機系滑剤、ポリエチレンワックスやパラフィンワックス等の炭化水素系滑剤、シリコン樹脂粒子、フッ素樹脂粒子等を用いることができ、いわゆる常温(室温)で固体の粒子状滑剤だと、滑り性と艶消し性との両方の効果が得られ易い。 For example, when a particulate lubricant is added to the resin solution absorption layer or the light shielding layer, a metal soap such as calcium stearate, an inorganic lubricant such as talc or molybdenum disulfide, carbonization such as polyethylene wax or paraffin wax. Hydrogen-based lubricants, silicon resin particles, fluororesin particles, and the like can be used, and so-called solid lubricants at room temperature (room temperature) can easily achieve both effects of slipping and matting.
また、樹脂溶液吸収層あるいは遮光層に、常温で液状の滑剤としてフッ素系化合物やシリコーンオイルを用いることもできる。 Moreover, a fluorine-type compound and silicone oil can also be used for a resin solution absorption layer or a light shielding layer as a lubricant liquid at normal temperature.
本発明の光学機器用遮光部材を塗布の方法により製造するには、まず、合成樹脂フィルムからなる基材の少なくとも一方の面に、バインダー樹脂及びフィラーを含み、溶媒あるいは分散媒により混合した樹脂溶液吸収層塗布液を、ディップコート、バーコート、ダイコート、グラビアコート、エアナイフコート等の従来公知の塗布方法により塗布し、乾燥させて成膜する。 In order to produce the light shielding member for an optical device according to the present invention by a coating method, first, a resin solution containing a binder resin and a filler and mixed with a solvent or a dispersion medium on at least one surface of a substrate made of a synthetic resin film The absorbing layer coating solution is applied by a conventionally known coating method such as dip coating, bar coating, die coating, gravure coating, air knife coating, etc., and dried to form a film.
樹脂溶液吸収層塗布液の溶媒あるいは分散媒は、前述のように、水系、有機溶剤系、水系有機溶剤系の混合系が用いられる。なお水系とは、水単独のみならずアルコール類との混合系をも指すものとする。樹脂溶液吸収層塗布液には、前述の様に硬化剤等を添加することができ、その場合には、塗膜の架橋や硬化を行うために、適宜、成膜後に後加熱することもできる。 As the solvent or dispersion medium of the resin solution absorbing layer coating liquid, as described above, an aqueous, organic solvent, or aqueous organic solvent mixed system is used. The aqueous system refers to not only water alone but also a mixed system with alcohols. As described above, a curing agent or the like can be added to the resin solution absorption layer coating solution. In this case, post-heating can be appropriately performed after film formation in order to perform crosslinking and curing of the coating film. .
また、合成樹脂フィルムから成る基材の両方の面に樹脂溶液吸収層を設ける場合は、両面とも同時に樹脂溶液吸収層を成膜してもよいし、片面ずつ成膜してもよい。なお、樹脂用液吸収層と合成樹脂フィルムから成る基材との接着性を上げる等のために、予め、アンカー層を塗布してもよい。 Moreover, when providing the resin solution absorption layer on both surfaces of the base material made of the synthetic resin film, the resin solution absorption layer may be formed on both surfaces simultaneously, or may be formed on each side. An anchor layer may be applied in advance in order to increase the adhesion between the resin liquid absorbing layer and the base material made of the synthetic resin film.
次に、樹脂溶液吸収層の上に遮光層を積層する。先に成膜した樹脂溶液吸収層の上に、バインダー樹脂、黒色微粒子及びフィラーを含み、溶媒あるいは分散媒により混合した遮光層塗布液を、前述の従来公知の塗布方法により積層塗布し、乾燥させて成膜する。遮光層塗布液には、必要に応じて、滑剤や硬化剤等を添加することができる。硬化剤を添加する場合には、塗膜の架橋や硬化を行うために、適宜、成膜後に後加熱することもできる。 Next, a light shielding layer is laminated on the resin solution absorption layer. A light-shielding layer coating solution containing a binder resin, black fine particles and a filler and mixed with a solvent or a dispersion medium is laminated and applied by the above-mentioned conventionally known coating method on the resin solution absorption layer formed in advance, and dried. To form a film. A lubricant, a curing agent, or the like can be added to the light shielding layer coating solution as necessary. In the case of adding a curing agent, post-heating can be appropriately performed after film formation in order to perform crosslinking and curing of the coating film.
また、合成樹脂フィルムから成る基材の両面に遮光層を設ける場合は、前述のように樹脂溶液吸収層も予め該基材の両面に成膜しておいて、各樹脂溶液吸収層の上に遮光層を積層させる。この時に、遮光層の塗布は、片面ずつ行っても、両面同時に行ってもよく、本発明の範囲であれば、両面の各層の処方は違えても構わない。 In addition, when providing a light shielding layer on both surfaces of a base material made of a synthetic resin film, the resin solution absorption layer is also formed on both surfaces of the base material in advance as described above, and is formed on each resin solution absorption layer. A light shielding layer is laminated. At this time, the light-shielding layer may be applied on one side or on both sides at the same time. Within the scope of the present invention, the formulation of each layer on both sides may be different.

2.評価
以上のようにして実施例1〜14及び比較例1〜3で得られた光学機器用遮光部材、更に参考例1で得られたフィルムについて、下記の方法で物性の評価を行った。それぞれの結果を表1に示す。
2. Evaluation As described above, the physical properties of the light shielding members for optical devices obtained in Examples 1 to 14 and Comparative Examples 1 to 3 and the film obtained in Reference Example 1 were evaluated by the following methods. The results are shown in Table 1.
(1)遮光性
上記実施例1〜13及び比較例1〜3で得られた光学機器用遮光部材を、JIS K7651:1988に基づき光学濃度計〔TD−904、UVフィルター(Duv):グレタグマクベス社〕を用いて光学透過濃度を測定した。光学透過濃度が4.0を超えたものは光学機器用遮光部材として十分な透過濃度と認められる。
(1) Light-shielding properties The light-shielding members for optical devices obtained in Examples 1 to 13 and Comparative Examples 1 to 3 are optical densitometers [TD-904, UV filter (Duv): Gretag Macbeth based on JIS K7651: 1988. Was used to measure the optical transmission density. An optical transmission density exceeding 4.0 is recognized as a sufficient transmission density as a light shielding member for optical equipment.
(2)光沢性
実施例1〜13及び比較例1〜3で得られた光学機器用遮光部材、更に参考例1で得られたフィルムについて、JIS−Z8741:1997に基づき、測定角度60度で光沢度(鏡面光沢度、%)を測定した。この時の光沢度を「光沢度(前)」と表記した。この光沢度が低いほど初期状態の光沢性が良好であると認められ、光沢度(前)が2以下であれば光学機器用遮光部材として十分な光沢性と認められる。
(2) Glossiness About the light shielding member for optical equipment obtained in Examples 1 to 13 and Comparative Examples 1 to 3, and the film obtained in Reference Example 1 at a measurement angle of 60 degrees based on JIS-Z8741: 1997. The glossiness (mirror glossiness,%) was measured. The glossiness at this time was described as “glossiness (front)”. It is recognized that the lower the glossiness, the better the initial glossiness. If the glossiness (before) is 2 or less, the glossiness is sufficient as a light-shielding member for optical equipment.
(3)耐擦傷性
実施例1〜3及び比較例1〜3で得られた光学機器用遮光部材の遮光層表面について、耐擦試験機(NUS−ISO−1、スガ試験機社)を使用して、可動部と固定部に同じサンプル片を設置し、荷重500g、100往復の条件で耐擦試験を行った。その耐擦試験後の固定部に設置したサンプル片表面の光沢度(鏡面光沢度、%)を測定し、「光沢度(後)」とし、「〔光沢度(後)−光沢度(前)」の差を計算した。この差が小さいほど耐擦傷性が良好であると認められ、その差が1以内であれば光学機器用遮光部材として実用上十分であると認められる。
(3) Scratch resistance For the light-shielding layer surface of the light-shielding member for optical equipment obtained in Examples 1 to 3 and Comparative Examples 1 to 3, a scratch resistance tester (NUS-ISO-1, Suga Test Instruments Co., Ltd.) is used. Then, the same sample piece was placed on the movable part and the fixed part, and a rubbing resistance test was performed under the conditions of a load of 500 g and 100 reciprocations. Measure the glossiness (mirror glossiness,%) of the surface of the sample piece placed on the fixed part after the abrasion resistance test, and set it as "Glossiness (Rear)". The difference was calculated. It is recognized that the smaller this difference is, the better the scratch resistance is, and if the difference is within 1, the practically sufficient light-shielding member for optical equipment is recognized.
(4)帯電防止性
実施例1〜3及び比較例1〜3で得られた光学機器用遮光部材の表面抵抗率(Ω)を、JIS−K6911:1995に基づき測定した。表面抵抗率が106Ωオーダー以下であれば光学機器用遮光部材として実用上問題となる塵埃の付着等がなく、良好であると認められる。
(4) Antistatic property The surface resistivity (Ω) of the light shielding member for optical equipment obtained in Examples 1 to 3 and Comparative Examples 1 to 3 was measured based on JIS-K6911: 1995. When the surface resistivity is on the order of 10 6 Ω or less, it is recognized that there is no adhesion of dust, which is a practical problem as a light-shielding member for optical equipment, and is favorable.
表1の結果より、実施例1〜6では、遮光層の固形分付着量をほぼ一定にして、樹脂溶液吸収層の固形分付着量を変化させたものは、いずれも遮光性であるDuv、初期の光沢性である光沢度(前)、耐擦傷性である「光沢度(後)−光沢度(前)」、更に帯電防止性である表面抵抗値は良好なものであった。ただし実施例6に関しては、諸性能は良好であったが、樹脂溶液吸収層が厚膜のため、乾燥時間が他のものより長く必要だった。 From the results of Table 1, in Examples 1 to 6, the solid content adhesion amount of the light shielding layer was made substantially constant, and the solid content adhesion amount of the resin solution absorption layer was changed. The glossiness (front) as the initial glossiness, “glossiness (after)-glossiness (front)” as the scratch resistance, and the surface resistance value as antistatic properties were good. However, regarding Example 6, various performances were good, but since the resin solution absorption layer was thick, the drying time was longer than the others.
また、実施例7〜10では、樹脂溶液吸収層の固形分付着量をほぼ一定にして、遮光層の固形分付着量を変化させたが、やはり上記各々の性能は良好であった。ただし実施例7に関しては、遮光層が薄膜のため、他のものより遮光性が低めであり、光沢性も高めであった。 In Examples 7 to 10, the solid content adhesion amount of the resin solution absorption layer was made substantially constant and the solid content adhesion amount of the light shielding layer was changed, but each of the above performances was also good. However, in Example 7, since the light shielding layer was a thin film, the light shielding property was lower and the glossiness was higher than the others.
更に、実施例11および13では、樹脂溶液吸収層のバインダーを変化させ、また、実施例12では樹脂溶液吸収層のフィラー量を多く添加したが、いずれも上記諸性能は良好であった。 Furthermore, in Examples 11 and 13, the binder of the resin solution absorption layer was changed, and in Example 12, a large amount of filler was added to the resin solution absorption layer.
一方、比較例1では、樹脂溶液吸収層にフィラーを添加しなかったので、遮光層塗布液を積層塗布した時に、その樹脂溶液分の吸収性が悪かったと考えられ、光沢性、耐擦傷性、帯電防止性も悪かった。 On the other hand, in Comparative Example 1, since no filler was added to the resin solution absorption layer, it was considered that the absorption of the resin solution was poor when the light-shielding layer coating solution was laminated, and glossiness, scratch resistance, The antistatic property was also poor.
また、比較例2では、樹脂溶液吸収層と遮光層とを、上下逆にして積層したが、遮光層には樹脂溶液吸収層の樹脂溶液分がほとんど吸収されず、上記各々の性能は悪かった。 Further, in Comparative Example 2, the resin solution absorption layer and the light shielding layer were laminated upside down, but the resin solution content of the resin solution absorption layer was hardly absorbed in the light shielding layer, and each of the above performances was bad. .
更に、比較例3では、遮光層塗付液を基材に直接塗付したが、遮光層一層のみでは上記各々の性能は不十分であった。 Furthermore, in Comparative Example 3, the light shielding layer coating solution was directly applied to the substrate, but the above-mentioned performances were insufficient with only one light shielding layer.
なお、参考例1では、樹脂溶液吸収層のみの光沢性を測定したが、樹脂溶液吸収層一層のみでは光沢性は低くなかった。 In Reference Example 1, the glossiness of only the resin solution absorption layer was measured, but the glossiness was not low with only one resin solution absorption layer.
