I can do things.
以下、本発明の偽造防止用転写箔の一実施形態の構成の各層について詳細に説明する。 Hereinafter, each layer of the configuration of an embodiment of the transfer foil for preventing forgery of the present invention will be described in detail.
＜支持体＞
支持体１としては、厚みが安定しており、且つ耐熱性の高いポリエチレンテレフタレート樹脂フィルムを用いるのが一般的であるが、これに限るものではない。その他の材料としては、ポリエチレンナフタレート樹脂フィルム、ポリイミド樹脂フィルム等が耐熱性の高いフィルムとして知られており、同様の目的で使用する事が可能である。また、他のフ
ィルム、例えば、ポリエチレン、ポリプロピレン、耐熱塩化ビニル等の材料でも、本発明の偽造防止用転写箔の構成として使用される塗液の塗工条件や乾燥条件によっては使用可能である。また、転写層への影響が無い限りは、支持体に対し、帯電防止処理やマット加工、エンボス処理等の加工をしても良い。
<Support>
The support 1 is generally a polyethylene terephthalate resin film having a stable thickness and high heat resistance, but is not limited thereto. As other materials, polyethylene naphthalate resin films, polyimide resin films, and the like are known as films having high heat resistance, and can be used for the same purpose. Further, other films such as polyethylene, polypropylene, heat resistant vinyl chloride and the like can be used depending on the coating conditions and drying conditions of the coating liquid used as the constitution of the anti-counterfeit transfer foil of the present invention. Further, as long as there is no influence on the transfer layer, the support may be subjected to processing such as antistatic treatment, mat processing, and embossing processing.
＜保護層＞
保護層２は、支持体１から剥がれる層であり、剥離した後はＯＶＤ形成層３を覆い最表面に露出する。このため保護層２は機械的損傷や携帯時の擦り等の外的要因による損傷、生活物質（酒、水等）に対する耐性を備え、ＯＶＤ形成層３を保護する役目を果たしている。これらの性能及び耐性を有していれば、保護層２の材料として従来から公知の透明性の、熱可塑性樹脂、熱硬化性樹脂、紫外線或いは電子線硬化性樹脂のいずれの材料も使用する事ができる。その例としては、アクリル系樹脂、セルロース系樹脂、ポリエーテル系樹脂、ポリイミド樹脂、ポリカーボネート樹脂、ポリアミドイミド樹脂等の熱可塑性樹脂やウレタン系硬化樹脂や、メラミン硬化樹脂、エポキシ硬化樹脂等の熱硬化樹脂、エポキシ（メタ）アクリル、ウレタン（メタ）クリレート等の紫外線或いは電子線硬化樹脂が挙げられるが、本発明ではこれらに限定されるものではない。
<Protective layer>
The protective layer 2 is a layer that is peeled off from the support 1, and after the peeling, the OVD forming layer 3 is covered and exposed to the outermost surface. For this reason, the protective layer 2 has a resistance to mechanical damage, damage due to external factors such as rubbing during carrying, and resistance to living substances (alcohol, water, etc.), and plays a role of protecting the OVD formation layer 3. As long as it has such performance and resistance, any conventionally known transparent thermoplastic resin, thermosetting resin, ultraviolet ray or electron beam curable resin should be used as the material for the protective layer 2. Can do. Examples include thermoplastic resins such as acrylic resins, cellulose resins, polyether resins, polyimide resins, polycarbonate resins, and polyamideimide resins, and urethane cured resins, and thermosetting resins such as melamine cured resins and epoxy cured resins. Examples of the resin include ultraviolet rays such as resin, epoxy (meth) acryl, urethane (meth) acrylate, and electron beam curable resins, but the invention is not limited thereto.
また、転写条件等により支持体１と保護層２の剥離が困難である場合には、例えば図６に示すように、支持体１と保護層２の間に別途従来既知の剥離層５５を設けても良く、剥離が軽すぎる場合には同様に従来既知の易接着処理を行って剥離を調整しても良い。更に、保護層２には、耐摩擦性を付与する目的で、既知の滑剤を適宜選択して添加する事が可能である。 Further, when it is difficult to peel off the support 1 and the protective layer 2 due to transfer conditions or the like, a conventionally known release layer 55 is separately provided between the support 1 and the protective layer 2 as shown in FIG. Alternatively, if the peeling is too light, the peeling may be adjusted similarly by performing a conventionally known easy adhesion treatment. Further, a known lubricant can be appropriately selected and added to the protective layer 2 for the purpose of imparting friction resistance.
＜ＯＶＤ形成層＞
ＯＶＤ形成層は、光回折等の光学的効果を発現する層であり、レリーフ型のＯＶＤの場合には、その主となる材料は熱可塑性樹脂、熱硬化性樹脂、紫外線或いは電子線硬化性樹脂のいずれであっても良い。
<OVD formation layer>
The OVD forming layer is a layer that expresses optical effects such as light diffraction. In the case of a relief type OVD, the main material is a thermoplastic resin, a thermosetting resin, an ultraviolet ray or an electron beam curable resin. Either may be sufficient.
ＯＶＤ形成層に使用可能な材料は、例えば、アクリル系樹脂、エポキシ系樹脂、セルロース系樹脂、ビニル系樹脂等の熱可塑性樹脂や、反応性水酸基を有するアクリルポリオールやポリエステルポリオール等にポリイソシアネートを架橋剤として添加、架橋したウレタン樹脂や、メラミン系樹脂、フェノール系樹脂等の熱硬化樹脂、エポキシ（メタ）アクリル、ウレタン（メタ）アクリレート等の紫外線或いは電子線硬化樹脂を、単独もしくはこれらを複合して使用できる。また、前記以外の樹脂であっても、ＯＶＤ画像を形成可能であれば適宜使用できる。 Examples of materials that can be used for the OVD formation layer include cross-linking of polyisocyanates to thermoplastic resins such as acrylic resins, epoxy resins, cellulose resins, and vinyl resins, and acrylic polyols and polyester polyols having reactive hydroxyl groups. Addition and crosslinking of urethane resin, melamine resin, phenolic resin and other thermosetting resins, epoxy (meth) acrylic, urethane (meth) acrylate and other ultraviolet or electron beam curable resins, alone or in combination Can be used. Moreover, even if it is resin other than the above, if an OVD image can be formed, it can be used suitably.
＜ＯＶＤ効果層ａ＞
ＯＶＤ効果層ａはＯＶＤ形成層の光学的効果を高めるため、ＯＶＤ形成層を構成する材料とは屈折率の異なる材料からなる。また、本発明の偽造防止転写箔は、検証時に透過光を利用する媒体であるため、光反射性と光透過性の両性質を有した材料をある一定の厚さにて設ける必要がある。用いる材料としては、ＯＶＤ形成層３と屈折率が異なり、且つ反射効果の高いＡｌ、Ｓｎ、Ｃｒ、Ｎｉ、Ｃｕ、Ａｕ等の金属材料が挙げられる。
<OVD effect layer a>
The OVD effect layer a is made of a material having a refractive index different from that of the material constituting the OVD formation layer in order to enhance the optical effect of the OVD formation layer. In addition, since the anti-counterfeit transfer foil of the present invention is a medium that utilizes transmitted light at the time of verification, it is necessary to provide a material having both light reflectivity and light transmissivity at a certain thickness. Examples of the material to be used include metal materials such as Al, Sn, Cr, Ni, Cu, and Au, which have a refractive index different from that of the OVD forming layer 3 and have a high reflection effect.
このＯＶＤ効果層ａは全面に設けられていても良いが、例えば図７のような文字や絵柄等のパターンで形成されても良い、この場合、意匠性を向上すると共に加工を複雑にし、より高い偽造防止効果を付与する事ができる。 The OVD effect layer a may be provided on the entire surface, but may be formed with, for example, a pattern such as a character or a picture as shown in FIG. 7. In this case, the design is improved and the processing is more complicated. A high anti-counterfeiting effect can be imparted.
ＯＶＤ効果層ａをパターン状に設ける手法としては、溶解性の樹脂をパターン状に形成した後に金属薄膜を設け、溶解性樹脂とその部分の金属薄膜層を洗浄して除去する方法や、金属薄膜層に耐酸或いは耐アルカリ性樹脂を用いてパターン状に印刷した後、金属薄膜を酸やアルカリでエッチングする方法、或いは光を露光する事によって、溶解する或いは溶解し難くなる樹脂材料を塗布し、所望のパターン状のマスク越しに露光した後、不要部分を洗浄或いはエッチングで除去する方法等が挙げられる。以上は一例であり、これらに限定されるものではなく、公知の部分的に金属薄膜を形成する技術であれば適宜利用可能である
また、ＯＶＤ効果層ａをパターン状に設ける別の手法としては、金属光沢インキによってＯＶＤ効果層ａを形成する方法がある。すなわち、金属光沢インキの一部分で、文字又は絵柄のいずれかを表す形状或いは輪郭を形成する。ここで、金属光沢インキは金属粉または金属微粒子が有機高分子樹脂中に分散されているもので、用いられる金属粉としては、例えば、アルミペースト、銅と亜鉛の金属粉末であるブロンズパウダー等が挙げられる。用いられる有機高分子樹脂としては、例えば、ポリ塩化ビニル系、塩化ビニルー酢酸ビニル共重合体等の熱可塑性樹脂や、メラミン系、尿素系等の熱硬化性高分子樹脂等が挙げられる。また、これらの有機高分子樹脂を溶解する有機溶剤としては、例えば、酢酸エチル、酢酸ブチルなどのエステル類、トルエン、キシレンなどの芳香族炭化水素類等を単独または任意に配合して用いる。
As a method of providing the OVD effect layer a in a pattern, a method of providing a metal thin film after forming a soluble resin in a pattern, and washing and removing the soluble resin and the metal thin film layer in the portion, or a metal thin film After the layer is printed in a pattern using an acid- or alkali-resistant resin, a method of etching the metal thin film with an acid or alkali, or a resin material that dissolves or becomes difficult to dissolve by exposing to light is applied. For example, a method of removing unnecessary portions by washing or etching after exposure through a mask having the above-described pattern may be used. The above is an example, and the present invention is not limited to these. Any known technique for partially forming a metal thin film can be used as appropriate. Another method for providing the OVD effect layer a in a pattern is as follows. There is a method of forming the OVD effect layer a with a metallic gloss ink. That is, a shape or outline representing either a character or a picture is formed by a part of the metallic gloss ink. Here, the metallic gloss ink is one in which metal powder or metal fine particles are dispersed in an organic polymer resin. Examples of the metal powder used include aluminum paste and bronze powder that is a metal powder of copper and zinc. Can be mentioned. Examples of the organic polymer resin used include thermoplastic resins such as polyvinyl chloride and vinyl chloride-vinyl acetate copolymers, and thermosetting polymer resins such as melamine and urea. Moreover, as an organic solvent which dissolves these organic polymer resins, for example, esters such as ethyl acetate and butyl acetate, aromatic hydrocarbons such as toluene and xylene, and the like are used alone or arbitrarily in combination.
＜ＯＶＤ効果層ｂ＞
ＯＶＤ効果層ｂはＯＶＤ効果層ａと同様の金属材料または金属光沢インキからなり、ＯＶＤ効果層ａとは異なる文字や絵柄等のパターンで形成する。ＯＶＤ効果層ａが、既にある特定の文字や絵柄等のパターンで形成されている場合は、図２に示すように、ＯＶＤ効果層ｂのパターンが、支持体１側から見た場合にＯＶＤ効果層ａのパターンに隠れるように設けなくてはならない。即ちＯＶＤ効果層ｂは、ＯＶＤ形成層３や保護層２と接しないように設ける必要がある。
<OVD effect layer b>
The OVD effect layer b is made of the same metal material or metallic gloss ink as that of the OVD effect layer a, and is formed with a pattern such as characters and patterns different from the OVD effect layer a. When the OVD effect layer a is already formed with a pattern such as a specific character or pattern, as shown in FIG. 2, the OVD effect layer b has a OVD effect when viewed from the support 1 side. It must be provided so as to be hidden by the pattern of layer a. That is, the OVD effect layer b needs to be provided so as not to contact the OVD formation layer 3 and the protective layer 2.
ＯＶＤ効果層ａとＯＶＤ効果層ｂの膜厚は、金属薄膜層を用いる場合は、材料の光透過性や反射性により、０．１〜１００ｎｍで形成される。また、金属光沢インキを使用する場合には、金属薄膜層と同等の光透過性又は反射性が得られる膜厚とする。ここで、ＯＶＤ効果層ａは少なくとも１０％以上８５％以下の光透過性を有している事が望ましく、またＯＶＤ効果層ｂは、ＯＶＤ効果層ａとＯＶＤ効果層ｂが複合した場合に、ＯＶＤ効果層ａ単独での光線透過率と比較して光透過率が５％以上低くなるように設ける必要がある。全体で５％以下の透過率では画像が暗く認識しづらくなる。また８０％以上ではＯＶＤ効果層ａの反射でＯＶＤ効果層ｂを隠すことが難しくなる。 The film thickness of the OVD effect layer a and the OVD effect layer b is 0.1 to 100 nm depending on the light transmissivity and reflectivity of the material when a metal thin film layer is used. Moreover, when using a metallic luster ink, it is set as the film thickness from which the light transmittance or reflectivity equivalent to a metal thin film layer is acquired. Here, it is desirable that the OVD effect layer a has a light transmittance of at least 10% to 85%, and the OVD effect layer b is a combination of the OVD effect layer a and the OVD effect layer b. It is necessary to provide the light transmittance of 5% or more lower than the light transmittance of the OVD effect layer a alone. When the transmittance is 5% or less as a whole, the image is dark and difficult to recognize. If it is 80% or more, it is difficult to hide the OVD effect layer b by reflection of the OVD effect layer a.
このようにＯＶＤ効果層ｂを形成する事により、支持体１側から本発明による偽造防止転写箔に向けて光を照射し、支持体１方向から観察した場合、ＯＶＤ効果層ｂのパターンは、ＯＶＤ効果層ａの光反射によって隠蔽される。また、逆側から光を照射し支持体１側より観察した場合、ＯＶＤ効果層ｂのパターン形状はＯＶＤ効果層ａと複合した透過光明暗パターンとして観察される。 By forming the OVD effect layer b in this way, when irradiating light from the support 1 side toward the anti-counterfeit transfer foil according to the present invention and observing from the direction of the support 1, the pattern of the OVD effect layer b is It is hidden by the light reflection of the OVD effect layer a. Moreover, when irradiating light from the reverse side and observing from the support body 1 side, the pattern shape of the OVD effect layer b is observed as a transmitted light bright / dark pattern combined with the OVD effect layer a.
ＯＶＤ効果層ａやＯＶＤ効果層ｂの膜厚によっては、図３や図４に示すように、パターン状に設けたＯＶＤ効果層ａやＯＶＤ効果層ｂの間を埋めるように、光透過性の高い材料からなるＯＶＤ効果層ｃを設けても良い。用いる材料としては、例えばＴｉＯ2、Ｓｉ2Ｏ3、ＳｉＯ、Ｆｅ2Ｏ3、ＺｎＳ等が挙げられる。ＯＶＤ効果層ｃを設ける事によって転写箔全体の厚みが均一となり、ＯＶＤ効果層ｂのパターン隠蔽効果が更に高くなる。 Depending on the film thickness of the OVD effect layer a and OVD effect layer b, as shown in FIGS. 3 and 4, the light transmitting property may be filled so as to fill the space between the OVD effect layer a and the OVD effect layer b provided in a pattern. An OVD effect layer c made of a high material may be provided. Examples of the material to be used include TiO 2 , Si 2 O 3 , SiO, Fe 2 O 3 , and ZnS. By providing the OVD effect layer c, the thickness of the entire transfer foil becomes uniform, and the pattern hiding effect of the OVD effect layer b is further enhanced.
＜接着層＞
接着層１１は、本発明の偽造防止転写箔を任意の偽造防止媒体に形成するためのものである。ホットスタンプ等を用いて熱及び圧力で任意の対象物へ接着・転写させる。接着層を設ける方法としては、グラビア印刷法やスクリーン印刷法、オフセット印刷法等の公知の手法が適宜用いられる。
