Description
本考案は、合成樹脂系基材の表面に少なくとも表面処理層、デジタル印刷法にて形成された絵柄印刷層が積層され、基材の積層した側と反対面に立体造形成形品に合せて型抜きされたシートを貼り合わせ、加飾時型抜きシートが成形用治具となる立体造形成形品加飾用フィルム及び加飾装置並びに立体造形加飾成形品に関する。 In the present invention, at least a surface treatment layer and a pattern printing layer formed by a digital printing method are laminated on the surface of a synthetic resin base material, and a mold is formed on the surface opposite to the side on which the base material is laminated according to a three-dimensional molded article. The present invention relates to a three-dimensional molded article decorative film, a decoration device, and a three-dimensional decorative decoration molded product in which the punched sheets are bonded together, and the decorative die-cut sheet becomes a molding jig.
従来、立体造形成形品への加飾方法として、合成樹脂系基材、木質系基材、無機質系基材、金属系基材等の各種の基材表面に形成された画像層が積層された加飾用フィルムを、熱転写法、真空成型法、真空熱転写法、真空圧空熱転写法、インモールド転写法等により加飾することで行っていた。 Conventionally, image layers formed on the surface of various base materials such as synthetic resin base materials, wood base materials, inorganic base materials, metal base materials, etc. have been laminated as a method for decorating a three-dimensional molded article. The decorative film was decorated by a thermal transfer method, a vacuum forming method, a vacuum thermal transfer method, a vacuum pressure air heat transfer method, an in-mold transfer method, or the like.
加飾用フィルムは、グラビア印刷、シルク印刷、オフセット印刷、凸版印刷、フレキソ印刷等で絵柄印刷を行って画像層を形成している。通常、印刷見当精度の観点から基材には耐熱性が重視され、ヤング率の低い伸びの少ないポリエステルフィルムが多用されている。ところがポリエステルフィルムを基材として用いると、立体造形成形品に対する加飾時、加飾用フィルムの形状追随性不足、皺の発生、空気溜まりによる加飾用フィルムの成形品からの剥離、等の不具合が発生することが多く、良好な立体造形加飾成形品を得ることが困難であった。 The decorative film is subjected to pattern printing by gravure printing, silk printing, offset printing, letterpress printing, flexographic printing, and the like to form an image layer. Usually, from the viewpoint of printing registration accuracy, heat resistance is important for the base material, and polyester films with low Young's modulus and low elongation are often used. However, when a polyester film is used as a base material, when decorating a three-dimensional shaped molded product, problems such as lack of shape followability of the decorative film, generation of wrinkles, peeling of the decorative film from the molded product due to air accumulation, etc. This often occurs, and it is difficult to obtain a good three-dimensional shaped decorative molded product.
この解決方法としては加飾時の真空成型法、真空圧空熱転写法においてヤング率の高い伸びの大きいポリオレフィンフィルム等が使用することが知られている。しかし前記手法による加飾時に加飾用フィルムに予熱をかけることから、該加飾用フィルムが熱でダメージを受け、成形品との位置合わせが難しく、パターン印刷は困難で全面エンドレス柄に制限されてしまうという問題がある。 As this solution, it is known that a polyolefin film having a high Young's modulus and a large elongation is used in a vacuum forming method at the time of decoration and a vacuum pressure air heat transfer method. However, since the decorative film is preheated during the decoration by the above method, the decorative film is damaged by heat, it is difficult to align with the molded product, pattern printing is difficult, and the entire surface is limited to an endless pattern. There is a problem that it ends up.
また、一方、伸縮性の大きい材料、例えば熱可塑性ポリウレタン樹脂を基材とした場合に、グラビア印刷で画像を形成する際に、図柄の位置合わせを行うことが困難な点を解消するために、例えば特許文献１では、熱可塑性ポリウレタン樹脂からなる基材層と、１０ｋｇｆ／ｍでの伸び率が０．３％以下である支持体層とを剥離可能に積層することが提案されている。 On the other hand, in the case of using a material having a large stretch, for example, a thermoplastic polyurethane resin as a base material, when forming an image by gravure printing, in order to eliminate the difficulty of performing pattern alignment, For example, Patent Document 1 proposes that a base material layer made of a thermoplastic polyurethane resin and a support layer having an elongation rate of 0.3% or less at 10 kgf / m are detachably laminated.
しかしながら、特許文献１の構成では、画像層を形成する際に図柄の位置合わせを行うことができるよう、１０ｋｇｆ／ｍでの伸び率が０．３％以下の支持体層を設けているにすぎず、印刷工程を経た後には剥離するから、成形品へ加飾用フィルムを用いた加飾時には支持体層が存在しないので、上記と同じく、加飾時に加飾用フィルムに予熱かけると熱でダメージを受け、成形品との位置合わせが難しくなるといった問題があった。 However, in the configuration of Patent Document 1, only a support layer having an elongation rate of 0.3% or less at 10 kgf / m is provided so that the pattern can be aligned when the image layer is formed. In addition, since the support layer does not exist when decorating the molded product with the decorative film, since it peels after passing through the printing process, as described above, when the pre-heated decorative film is decorated with heat There was a problem that it was difficult to align with the molded product due to damage.
本考案が解決しようとする問題は、従来の加飾用フィルムは、基材が印刷見当精度の問題からヤング率の低い、伸びの少ないフィルムを使用したり、加飾時に剥離する支持体層を設けたりしていたが、画像層を有した基材（加飾用フィルム）を立体造形成形品に加飾する時に、皺、空気溜まりが生じて加飾用フィルムの成形品から剥離する点、また、ヤング率の高いフィルムにおいては、広範な意匠に加飾できない点、である。 The problem to be solved by the present invention is that the conventional decorative film uses a substrate with a low Young's modulus and a low elongation due to the problem of printing registration accuracy, or a support layer that peels off during decoration. Although it was provided, when decorating a three-dimensional molded product with a base material (decorative film) having an image layer, wrinkles, a point where air retention occurs and peels off the molded product of the decorative film, In addition, in a film having a high Young's modulus, it cannot be decorated in a wide range of designs.
本考案は、上記課題を解決し、立体造形成形品表面において加飾用フィルムに皺や剥離等のない画像を確実に形成（加飾）でき、かつ広範な意匠に加飾できる立体成形品加飾用フィルムを提供することを目的としている。 The present invention solves the above-mentioned problems, and can reliably form an image without wrinkles or peeling on the decorative film surface on the surface of the three-dimensional molded article (decoration), and add a three-dimensional molded article that can be decorated to a wide range of designs. The purpose is to provide a decorative film.
そして、本考案は、上記目的を達成するため、基材の一方の面に少なくとも表面処理層、印刷層が形成され、該基材の他方の面に、立体造形成形品に合わせ型抜きされ、成形品への加飾時に成形用治具となる型抜きシートを貼り合わせたことを最も主要な構成としている。 And, in order to achieve the above object, the present invention has at least a surface treatment layer and a printing layer formed on one surface of the base material, and on the other surface of the base material, is die-cut according to the three-dimensional molded article, The most main configuration is that a die-cutting sheet, which becomes a molding jig, is bonded to the molded product.
本考案によれば、型抜きシートを基材の、印刷層が形成された側とは反対面に貼り合わせることで、加飾成型時に皺や空気溜まりを解消でき、ヤング率の高い基材にも絵柄の制限を受けることなく高品質の印刷が可能で、したがって、広範な意匠に良好な加飾が可能となり、この結果、良好な立体造形加飾成形品を得ることができる。 According to the present invention, by sticking the die-cutting sheet to the surface of the substrate opposite to the side on which the printed layer is formed, it is possible to eliminate wrinkles and air accumulation during decorative molding, and to a substrate with a high Young's modulus. In addition, high quality printing is possible without being limited by the pattern, and therefore, a wide range of designs can be well decorated, and as a result, a good three-dimensional shaped decorative molded product can be obtained.
図１の模式的断面図に示すように本考案の立体造形加飾用フィルムＡ（以下、加飾用フィルムＡと記す）は、基材ａ２の一方の面上に、加飾する立体造形成形品の型抜きがなされた型抜きシートａ１が例えばラミネート法により貼り合わせている。 As shown in the schematic cross-sectional view of FIG. 1, the three-dimensional decorative film A of the present invention (hereinafter referred to as a decorative film A) is decorated on one surface of the base material a2. A die-cutting sheet a1 from which a product has been die-cut is bonded by, for example, a laminating method.
そして、基材ａ２の型抜きシートａ１を貼り合わせた側と反対面に、表面処理層ａ３、絵柄印刷層ａ４（画像層）が順次形成されている。但し、本考案の加飾用フィルムＡは基材ａ２における型抜きシートａ１を貼り合わせた側と反対面の積層構成は、表面処理層ａ３、絵柄印刷層ａ４の他に多層化しても構わないし、積層順も前記に限定されない。 And the surface treatment layer a3 and the pattern printing layer a4 (image layer) are formed in order on the opposite side to the side which bonded the die-cut sheet | seat a1 of the base material a2. However, the decorative film A of the present invention may be multilayered in addition to the surface treatment layer a3 and the pattern printing layer a4 in the laminated structure on the surface opposite to the side where the die-cut sheet a1 is bonded to the base material a2. The stacking order is not limited to the above.
型抜きシートａ１は、例えば図３（ａ）に示すスマートフォン用の型抜きシートｃ１、図３（ｂ）に示すゴルフボール用の型抜きシートｃ２、コンピュータのマウス用の型抜きシートｃ３のように、加飾する基材ａ２、表面処理層ａ３、絵柄印刷層ａ４が位置する部位が型抜きされている。 The die cutting sheet a1 is, for example, a die cutting sheet c1 for a smartphone shown in FIG. 3A, a die cutting sheet c2 for a golf ball shown in FIG. 3B, or a die cutting sheet c3 for a computer mouse. The parts where the base material a2, the surface treatment layer a3, and the pattern printing layer a4 to be decorated are located are stamped.
型抜きシートａ１は、耐熱性、寸法安定性の特性を有する熱可塑性樹脂から構成される。型抜きシートａ１の具体例としては、ポリエチレンテレフタレート、ポリブチレンテレフタレート等、また、耐熱性の高いポリエステル、ポリカーボネート、ポリアミド、ポリイミド、ポリメチルペンテン、アイオノマー等のプラスチックフィルム等、及びこれらから適宜選択した積層体等で構成する。 The die-cut sheet a1 is composed of a thermoplastic resin having heat resistance and dimensional stability characteristics. Specific examples of the die-cut sheet a1 include polyethylene terephthalate, polybutylene terephthalate, etc., high heat-resistant polyester, polycarbonate, polyamide, polyimide, polymethylpentene, ionomer, and other plastic films, and a laminate appropriately selected from these. Consists of body etc.
また、型抜きシートａ１の厚さは、強度、耐熱性等を考慮すると、７５〜１８８μｍの範囲が適切である。型抜きシートａ１が７５μｍより薄いと強度や耐熱性に乏しくなり、１８８μｍより厚いと立体造形加飾用フィルムＡの全体厚みが増し、型抜きシートａ１と基材ａ２の間に段差が生じて加飾成型時の皺、空気溜まりの原因となる可能性がある。 Further, the thickness of the die-cut sheet a1 is suitably in the range of 75 to 188 μm in consideration of strength, heat resistance and the like. If the die-cut sheet a1 is thinner than 75 μm, the strength and heat resistance are poor. If the die-cut sheet a1 is thicker than 188 μm, the overall thickness of the three-dimensional decorative film A increases, and a step is generated between the die-cut sheet a1 and the base material a2. There is a possibility of causing trapping and air accumulation during decoration molding.
基材ａ２は、高ヤング率（引張弾性率）、高引張強さ、高引張破壊伸度の特性を有する熱可塑性樹脂から構成される。基材ａ２の具体例としては高ヤング率の特性を有した、ポリプロピレン、ポリオレフィン、ポリエチレンの誘導体、ポリ塩化ビニル、ポリ塩化ビニリデン等のプラスチックフィルム、及びこれらから適宜選択した積層体等で構成する。 The base material a2 is composed of a thermoplastic resin having characteristics of high Young's modulus (tensile elastic modulus), high tensile strength, and high tensile fracture elongation. Specific examples of the base material a2 include a plastic film such as polypropylene, polyolefin, a polyethylene derivative, polyvinyl chloride, and polyvinylidene chloride, and a laminate appropriately selected from these, having high Young's modulus characteristics.
また、基材ａ２は、延伸されたものであってもよいし、未延伸であってもよい。ヤング率（引張弾性率）は４．８Ｇｐａ以上、引張破壊強さは３６０Ｍｐａ以上、引張破壊伸度は２１０％以上、フィルム厚さは１０〜５０μｍの範囲のものが適切である。 The base material a2 may be stretched or unstretched. It is appropriate that the Young's modulus (tensile modulus) is 4.8 Gpa or more, the tensile fracture strength is 360 Mpa or more, the tensile fracture elongation is 210% or more, and the film thickness is in the range of 10 to 50 μm.
ヤング率、引張破壊強さ、引張破壊伸度が上記数値未満の場合には、加飾成型時に、フィルムの伸びが乏しくなり、皺や破れが生じる可能性がある。また、基材ａ２のフィルム厚さが、１０μｍより薄いと強度が乏しくなり破れる可能性があり、５０μｍより厚いと加飾用フィルムＡの全体の厚みが増し、成形品の表面性状（凹凸等）への追従性が乏しくなる可能性がある。 When the Young's modulus, tensile fracture strength, and tensile fracture elongation are less than the above values, the film may be poorly stretched during decorative molding, and wrinkles and tears may occur. Further, if the film thickness of the substrate a2 is less than 10 μm, the strength may be reduced and the film may be broken. If the film thickness is more than 50 μm, the overall thickness of the decorative film A increases, and the surface properties (unevenness, etc.) of the molded product There is a possibility that the follow-up performance becomes poor.
表面処理層ａ３は、剥離性、感熱接着性の両方の特性を兼ね備えた樹脂で構成される。表面処理層ａ３を構成する樹脂としては、フッ素系樹脂、アクリル系樹脂（アクリル系樹脂とメタアクリル系樹脂の両者を含む意味で使用）、ウレタン樹脂、酢酸系ビニル樹脂、アクリル系ビニール樹脂、ポリスチレン樹脂等の各種樹脂が使用でき、単独または２種以上の混合物で使用してもよい。 The surface treatment layer a3 is composed of a resin having both properties of peelability and heat-sensitive adhesiveness. As the resin constituting the surface treatment layer a3, fluorine resin, acrylic resin (used to include both acrylic resin and methacrylic resin), urethane resin, acetic acid vinyl resin, acrylic vinyl resin, polystyrene Various resins such as resins can be used, and they may be used alone or in a mixture of two or more.
表面処理層ａ３は、特に、分子量が１００００〜３００００、ガラス転移点温度が５０℃以下の塩酢ビアクリル共重合樹脂を選択することが好ましい。熱処理層ａ３として採用する材料の分子量が１００００より低いと剥離性が悪くなり、３００００より高くなると感熱接着性能が乏しくなる。また、熱処理層ａ３として採用する材料のガラス転移点温度が５０℃より高くなると感熱接着性能が乏しくなる。 As the surface treatment layer a3, it is particularly preferable to select a chloroacetic acid biacrylic copolymer resin having a molecular weight of 10,000 to 30,000 and a glass transition temperature of 50 ° C. or less. When the molecular weight of the material used as the heat treatment layer a3 is lower than 10,000, the peelability is deteriorated, and when it is higher than 30000, the heat-sensitive adhesive performance is poor. Moreover, when the glass transition point temperature of the material adopted as the heat treatment layer a3 is higher than 50 ° C., the heat-sensitive adhesive performance becomes poor.
表面処理層ａ３には、塗工適性改善や光沢度調整の観点から、レベリング剤、消泡剤、界面活性剤、蛍光増白剤、紫外線吸収剤、滑剤（ポリエチレンワックス・パラフィンワックス・シリカ等）の添加剤を添加してもよい。 For the surface treatment layer a3, a leveling agent, an antifoaming agent, a surfactant, a fluorescent brightening agent, an ultraviolet absorber, a lubricant (polyethylene wax, paraffin wax, silica, etc.) from the viewpoint of improving coating suitability and glossiness adjustment. These additives may be added.
また、絵柄印刷層ａ４を効果的に保護しかつ立体造形成形品の加飾時における剥離性の向上及び接着性を確保するため、表面処理層ａ３は、膜厚２〜５μｍであることが好ましく、２μｍより薄い場合は加飾成型時の密着性が乏しくなり、５μｍより厚い場合は箔バリが発生し易くなる。 Moreover, in order to protect the pattern printing layer a4 effectively and to ensure the improvement of peelability and adhesion during the decoration of a three-dimensional molded article, the surface treatment layer a3 preferably has a thickness of 2 to 5 μm. If it is thinner than 2 μm, the adhesion at the time of decorative molding is poor, and if it is thicker than 5 μm, foil burrs are likely to occur.
絵柄印刷層ａ４は、公知のグラビア印刷・シルク印刷・オフセット印刷・フレキソ印刷等で絵柄画像を形成するが、絵柄画像の再現性及び伸縮性のある基材に対して良好な絵柄合わせ精度を得る観点からデジタル印刷機を選択するのが好ましい。 The pattern printing layer a4 forms a pattern image by known gravure printing, silk printing, offset printing, flexographic printing, etc., but obtains good pattern matching accuracy with respect to the reproducibility of the pattern image and the stretchable base material. It is preferable to select a digital printing machine from the viewpoint.
デジタル印刷方式としては、レーザープリンター方式、サーマル熱転写方式、インクジェット方式等の各種方式を使用すればよい。 As a digital printing method, various methods such as a laser printer method, a thermal thermal transfer method, and an ink jet method may be used.
本考案の加飾用フィルムＡを用いて図２に示す加飾装置Ｂにより、立体造形加飾成形品を得る。次に、図２を参照して該加飾装置Ｂの構成と共に本考案の立体造形成形品の加飾について説明する。 Using the decorative film A of the present invention, a three-dimensional shaped decorative molded product is obtained by the decorative device B shown in FIG. Next, with reference to FIG. 2, the decoration of the three-dimensional molded product of this invention is demonstrated with the structure of this decoration apparatus B. FIG.
加飾装置Ｂは、第１チャンバｂ１内に、可動式ヒータｂ２が設けられ、さらに孔が複数形成され、立体造形成形品を載置するための孔開鋼板ｂ３が設けられている。さらに、加飾装置Ｂは、孔開鋼板ｂ３の下部に第２チャンバｂ４が設けられ、この第２チャンバｂ４内を吸引して、孔開鋼板ｂ３の孔を介して第１チャンバｂ１内の空気を吸引するバキュームポンプｂ５が設けられている。 The decorating apparatus B is provided with a movable heater b2 in the first chamber b1, further formed with a plurality of holes, and provided with a perforated steel sheet b3 for placing a three-dimensional molded product. Furthermore, the decoration device B is provided with a second chamber b4 at the lower portion of the perforated steel sheet b3, sucks the inside of the second chamber b4, and air in the first chamber b1 through the hole of the perforated steel sheet b3. Is provided with a vacuum pump b5.
上記構成の加飾装置Ｂにおいて加飾用フィルムＡを用いて立体造形成形品Ｃに加飾するには、次のようにして行う。まず、第１チャンバｂ１を開けて、孔開鋼板ｂ３上に立体造形成形品Ｃを、加飾部位が可動式ヒータｂ２に面するよう載置する。続いて、立体造形成形品Ｃ上に、加飾用フィルムＡを、型抜きシートａ１が可動式ヒータｂ２に面するよう載置する。 In order to decorate the three-dimensional molded article C using the decorative film A in the decoration device B having the above-described configuration, it is performed as follows. First, the first chamber b1 is opened, and the three-dimensional molded product C is placed on the perforated steel sheet b3 so that the decoration part faces the movable heater b2. Subsequently, the decorative film A is placed on the three-dimensional molded article C so that the die-cut sheet a1 faces the movable heater b2.
その後、第１チャンバｂ１をを閉め、バキュームポンプｂ５で吸引し、加飾用フィルムＡを立体造形成形品Ｃに圧着させる。このとき、型抜きシートａ１が立体造形成形品Ｃに対する基材ａ２、表面処理層ａ３、絵柄印刷層ａ４の押さえ治具となり、立体造形成形品Ｃと加飾用フィルムＡをほぼ完全に密着させることができる。 Then, the 1st chamber b1 is closed, it attracts | sucks with the vacuum pump b5, and the film A for decorating is crimped | bonded to the three-dimensional molded article C. At this time, the die-cut sheet a1 serves as a pressing jig for the base material a2, the surface treatment layer a3, and the pattern printing layer a4 with respect to the three-dimensional molded article C, and the three-dimensional molded article C and the decorative film A are almost completely adhered to each other. be able to.
続いて、可動式ヒータｂ２を移動及び熱風を発生するように稼働して、加飾の基本である熱及び圧をかける。この可動式ヒータｂ２を前後左右に移動させることにより、むらなく均一的に加飾用フィルムＡと立体造形成形品Ｃに熱・圧が加えられる。このとき、固定式ヒータを用いる場合と較べると、該固定式ヒータは、熱風のよく当る所と当らない所が発生し、条件のムラが発生し、皺や空気溜まりによる剥離が発生することがある。 Subsequently, the movable heater b2 is operated so as to move and generate hot air, and heat and pressure, which are the basics of decoration, are applied. By moving this movable heater b2 back and forth, and right and left, heat and pressure are uniformly applied to the decorative film A and the three-dimensional molded article C evenly. At this time, compared to the case where a fixed heater is used, the fixed heater may be exposed to hot air and not to contact, causing unevenness in conditions, and peeling due to soot and air accumulation may occur. is there.
次いで、バキュームポンプｂ５による吸引を停止し、第１チャンバｂ１を開け、圧着された加飾用フィルムＡと立体造形成形品Ｃを取り出す。その際、従来の真空圧空熱転写では、箔バリと密着保持及び皺解消の観点から、成形品を取り出した直後に加飾用フィルムＡ（基材ａ２）を剥がす事ができなかった。これに較べ、本考案では、加飾用フィルムＡを用いて可動式ヒータｂ２を備えた加飾装置Ｂを使用するので、良好な立体造形加飾成形品Ｃを得ることができる。 Next, the suction by the vacuum pump b5 is stopped, the first chamber b1 is opened, and the decorative film A and the three-dimensional molded article C that have been crimped are taken out. At that time, in the conventional vacuum pressure air-heat transfer, the decorative film A (base material a2) could not be peeled immediately after the molded product was taken out from the viewpoints of foil burr and adhesion maintenance and wrinkle elimination. In contrast, in the present invention, since the decoration device B provided with the movable heater b2 using the decoration film A is used, a good three-dimensional shaped decorative molded product C can be obtained.
