Description
本発明は、少なくとも、非接触型情報媒体、内貼り用紙、表紙用部材から成る冊子に、偽変造防止機能層を付与した非接触型情報媒体付属冊子に関する。 The present invention relates to a non-contact information medium-attached booklet in which a forgery and alteration prevention functional layer is added to a booklet composed of at least a non-contact information medium, an inner sheet, and a cover member.
近年、非接触ＩＣカードや非接触ＩＣタグを用いたシステムが普及する中、例えばパスポートや預貯金通帳等冊子に、非接触ＩＣモジュールとそれに接続されたアンテナからなるＩＣインレットを外装基材で挟み込んで非接触型情報媒体とし、この非接触型情報媒体を、カバークロスなどを用いた表紙用部材に貼り合わせた上で、内貼り用紙と本文用紙を取り付けて装丁した、電子データの記入や印字が可能な非接触型情報媒体付属冊子が開発され公知となっている。 In recent years, while systems using non-contact IC cards and non-contact IC tags have become widespread, for example, an IC inlet comprising a non-contact IC module and an antenna connected thereto is sandwiched between exterior base materials in a booklet such as a passport or a savings passbook. It is a non-contact type information medium, and this non-contact type information medium is attached to a cover member using a cover cloth, etc., and then the inner paper and text paper are attached and bound, and electronic data can be entered and printed. A possible non-contact information medium attached booklet has been developed and is publicly known.
その非接触型情報媒体付属冊子の一事例として、例えば、特許文献１（第３−５頁）には、第１の基材シートの上面側に、所定の広さの開口部を有する第２の基材シートが接着されて凹部が形成され、この凹部内にＩＣ チップとこれに接続されたコイルアンテナが備えられ、前記第１の基材シートの下面側に接着剤層が設けられている非接触型情報媒体と、この非接触型情報媒体が裏表紙の内面に貼付されてなる非接触型情報媒体付属冊子が開示されている。 As an example of the booklet attached to the non-contact type information medium, for example, Patent Document 1 (pages 3 to 5) has a second opening having a predetermined width on the upper surface side of the first base sheet. The substrate sheet is bonded to form a recess, an IC chip and a coil antenna connected to the IC chip are provided in the recess, and an adhesive layer is provided on the lower surface side of the first substrate sheet. A non-contact type information medium and a non-contact type information medium-attached booklet in which the non-contact type information medium is attached to the inner surface of a back cover are disclosed.
非接触型情報媒体付属冊子の１つである電子パスポートを例に取ると、多くの偽造と変造が報告されており、それらの偽変造を防止するため、冊子に偽変造防止機能を付加させることが行なわれている。冊子の偽造を防止するためには一般的に用いられている偽造防止技術を使用することが出来、例えば見る角度によって色が変化するインキ（ＯＶＩ）や、ＵＶライトに反応するＵＶ蛍光インキなどを印刷したり、用紙自体に特殊な蛍光を発する糸を漉き込んだり、セキュリティスレッドを挿入したりすることも行なわれている。また近年では機械検知によって偽変造を判別するため、例えば特許文献２（第２−４頁）には、可視光および赤外光に対して反射性を有する印刷基材上に、可視光領域では光透過性が高く且つ赤外波長領域では吸収を示す赤外吸収体を含有する赤外吸収層と、赤外波長領域における吸収のない黒色の色素を含有する着色層とを重層した印刷物が開示されている。 Taking an electronic passport, which is one of the booklets attached to non-contact information media as an example, many counterfeits and alterations have been reported, and in order to prevent these counterfeits, a function to prevent forgery and alteration should be added to the booklet. Has been done. To prevent counterfeiting of booklets, commonly used anti-counterfeiting technology can be used, such as ink (OVI) whose color changes depending on the viewing angle, UV fluorescent ink that reacts to UV light, etc. Printing, inserting a special fluorescent thread on the paper itself, and inserting a security thread are also performed. In recent years, for example, Patent Document 2 (page 2-4) discloses a technique for determining falsification by machine detection. Disclosed is a printed matter in which an infrared absorbing layer containing an infrared absorber having high light transmittance and absorbing in the infrared wavelength region and a colored layer containing a black pigment having no absorption in the infrared wavelength region are disclosed. Has been.
また、同じくパスポートを例に取ると、名前や顔写真などの個人情報の変造を防止するために、例えばホログラムフィルムのラミネートが施されていたり、レーザーエングレービングによって個人情報を記録してあったりする。 Similarly, taking a passport as an example, in order to prevent personal information such as name and face photo from being altered, for example, a hologram film is laminated or personal information is recorded by laser engraving. To do.
しかし、上で述べたように、非接触型情報媒体を冊子に貼り付けることで、簡単な方法で非接触型情報媒体付属冊子を製造できるという反面、この非接触型情報媒体を冊子から分離したり、別の偽造品と取り替えたりするといった変造も容易にできてしまうという問
題があった。さらには、このようにして変造が行なわれた場合でも冊子に変造の跡が残りにくく、真贋判定を行なうことが困難であるという問題があった。さらに、このような非接触型情報媒体は、ＩＣカードに代表されるように熱ラミネート方式で製造される事が主流になっている。これは熱可塑性の基材や熱可塑性の接着剤を使用してＩＣチップおよびアンテナを基材間に挟んで成形するものであり、製造が容易である反面、熱をかけることで分離することも可能であるため偽変造の対象になる可能性がある。
However, as mentioned above, a non-contact information medium attached booklet can be manufactured by a simple method by pasting the non-contact information medium on the booklet, but this non-contact information medium is separated from the booklet. There is also a problem that it can be easily altered such as replacing it with another counterfeit product. Furthermore, even when the alteration is performed in this manner, there is a problem that the trace of the alteration is unlikely to remain in the booklet and it is difficult to determine the authenticity. Further, such non-contact type information media are mainly manufactured by a heat laminating method as represented by an IC card. In this method, a thermoplastic base material or a thermoplastic adhesive is used to sandwich an IC chip and an antenna between the base materials, and it is easy to manufacture, but it can also be separated by applying heat. Because it is possible, it may be subject to falsification.
このような状況に対して、前述したような従来の偽変造防止技術は、基本的には紙幣や有価証券、パスポート冊子など、紙をベースとした印刷物の偽変造を防止するものであり、上記のように非接触型情報媒体を取り代えたりするような変造には効果が少ない。このため、この従来には存在しなかった偽変造を防止するとともに、このような偽変造品を容易に判断できるような偽変造防止技術の開発が必要とされていた。 For such situations, the conventional anti-counterfeiting technology as described above basically prevents counterfeiting of printed matter based on paper, such as banknotes, securities, and passport booklets. Thus, there is little effect for alteration such as replacing a non-contact type information medium. For this reason, it has been necessary to develop a forgery / alteration prevention technique that can prevent forgery / alteration that did not exist in the prior art and can easily determine such a falsification / alteration product.
本発明は、かかる従来技術の問題点を解決するものであり、非接触型情報媒体と内貼り用紙と表紙用部材からなる、非接触型情報媒体付属冊子において、前記非接触型情報媒体の偽変造防止機能を向上させ、かつ、偽変造品を簡便に判断することの出来る、非接触型情報媒体付属冊子を提供することをその課題としている。 The present invention solves such problems of the prior art.

本発明は以上の構成であるから、下記に示す如き効果がある。即ち、熱圧により加工された非接触型情報媒体を使用した冊子に対し、熱に反応する偽変造防止機能層を付与することによって、加熱によって非接触型情報媒体を分離するといった偽変造を防止することができる。また、非接触型情報媒体の構成に係るものであり、多孔質の熱可塑性基材に熱可塑性接着剤を塗布して熱圧により接着することで、簡易な方法で柔軟性と平滑性に優れた非接触型情報媒体を製造することができる。このような構成による非接触型情報媒体は特に熱によって分離される危険性があり、偽変造防止機能層を付与する事が重要である。
Since this invention is the above structure, there exist the following effects. In other words, by adding a falsification prevention function layer that reacts to heat to a booklet that uses a non-contact type information medium processed by heat pressure, it prevents falsification such as separation of the non-contact information medium by heating. can do. In addition, it relates to the structure of non-contact type information media, and is excellent in flexibility and smoothness by a simple method by applying a thermoplastic adhesive to a porous thermoplastic substrate and bonding it by hot pressure. In addition, a non-contact type information medium can be manufactured. The non-contact type information medium having such a configuration has a risk of being separated by heat in particular, and it is important to provide a falsification preventing function layer.
また、請求項１〜５に示すように、偽変造防止機能を内貼り用紙と非接触型情報媒体との間の接着剤層、または非接触型情報媒体と表紙用部材との間の接着剤層に付与することで、印刷等の余計な工程を追加することなく、偽変造防止効果を得ることができる。さらに、表紙用部材と非接触型情報媒体の間の接着剤層としてホットメルト接着剤を使用した場合には、その溶融温度より高い１３０℃以上の熱で反応するような材料を使用することで偽変造防止効果を得ることができる。このような場合にはそれぞれの接着剤に前記機能性色材層の色材を混合して使用することによって、偽変造防止機能を持つ接着剤層を容易に形成することが出来る。
In addition, as shown in claims 1 to 5 , an adhesive layer between an inner sheet and a non-contact type information medium or an adhesive between a non-contact type information medium and a cover member has a function of preventing falsification. By imparting to the layer, it is possible to obtain a falsification preventing effect without adding an extra step such as printing. Furthermore, when using a hot melt adhesive as the adhesive layer between the cover member and the non-contact type information medium, by using a material such as to react with the higher melting temperature 130 ° C. or more heat An anti-counterfeit effect can be obtained. In such a case, an adhesive layer having a function of preventing falsification can be easily formed by mixing and using the color material of the functional color material layer in each adhesive.
このような偽変造防止機能を判断する方法としては、大きく分けて目視で判断する方法と機械検知で判断する方法があり、偽変造防止機能層の種類と付与する場所に依存する。機械検知で判断する場合には、請求項１から５に示すように、冊子の各層の層間に偽変造防止機能層を設けたもので判断することが出来る。この場合には内貼り用紙や非接触型情報媒体の基材を通して確認することになるため、例えば熱により赤外領域での吸収ピーク波長や吸光度が変化する材料を用いることで実現できる。このように冊子の層間に偽変造防止機能層を設けた場合には外からは目視で確認できないため、偽変造を行なう者が気づきにくく、耐久性にも優れているという効果がある。
As a method for judging such a forgery / alteration prevention function, there are a method of judging by visual classification and a method of judgment by machine detection, which depend on the type of the forgery / alteration prevention functional layer and the place to be provided . Machine械検When judging in knowledge, as shown in claims 1-5 can be determined by those having a forgery prevention function layer between the layers of each layer of the booklet. In this case, since the confirmation is made through the inner sheet or the base material of the non-contact type information medium, for example, it can be realized by using a material whose absorption peak wavelength or absorbance changes in the infrared region due to heat. In this way, when the forgery / alteration prevention functional layer is provided between the booklet layers, since it cannot be visually confirmed from the outside, there is an effect that the person who performs the falsification is hardly noticed and has excellent durability.
本発明の非接触型情報媒体付属冊子を、一実施形態に基いて、図面を用いて以下に説明する。 A non-contact information medium attached booklet of the present invention will be described below with reference to the drawings based on an embodiment.
本発明の非接触型情報媒体付属冊子は、図１に示す実施形態例のような形状であり、表紙用部材（１１）とその内面に貼着する内貼り用紙（１２）との間に非接触型情報媒体（
１０）を挟み込んで接着され、これに複数の本文用紙（１３）が加わったものである。この非接触型情報媒体の一部であるＩＣインレットは、図２に示すように、アンテナシート基材（２０）とＩＣチップ（２１）とアンテナコイル（２２）とから構成される。このＩＣインレットは、例えば図３に示すように、２枚の外装基材（３０）の間に挟み込まれることで非接触型情報媒体（１０）を構成している。また、偽変造防止機能層を有する本発明の非接触型情報媒体付属冊子は、図４から図１０に示すように７種類の場所にそれぞれ該偽変造防止機能層（機能性色材層）（４０）や偽変造防止機能層（接着剤層）（４１）を設けることで構成することができる。
The non-contact type information medium-attached booklet of the present invention has a shape as in the embodiment shown in FIG. 1, and is non-between the cover member (11) and the inner sheet (12) adhered to the inner surface thereof. Contact information media (
10) is sandwiched and bonded, and a plurality of text sheets (13) are added thereto. As shown in FIG. 2, the IC inlet, which is a part of the non-contact type information medium, includes an antenna sheet substrate (20), an IC chip (21), and an antenna coil (22). For example, as shown in FIG. 3, the IC inlet is sandwiched between two exterior base materials (30) to constitute a non-contact type information medium (10). Further, the booklet attached to the non-contact type information medium of the present invention having the forgery / alteration prevention functional layer is provided with the forgery / alteration prevention functional layer (functional color material layer) in seven kinds of locations as shown in FIGS. 40) and a falsification preventing functional layer (adhesive layer) (41).
図２に示すＩＣインレットにおいては、アンテナ基材上にエッチング方式やワイヤボンディング方式、印刷アンテナ方式などによってアンテナが形成される。このアンテナに、ＩＣが溶接方式などによって接続される。また、ＩＣチップ（２１）とアンテナコイル（２２）とアンテナシート基材（２０）からなるＩＣインレットは、ＩＣチップ自身の厚みや、アンテナの厚み、ジャンパ線とアンテナの接合部や、アンテナシート基材自体の厚みなどにより、凹凸のあるシートとなっている。このＩＣインレットを外装基材（３０）の間に挟んで非接触型情報媒体に加工する際、外観上はこれらの凹凸を無くすことが望ましい。 In the IC inlet shown in FIG. 2, an antenna is formed on an antenna substrate by an etching method, a wire bonding method, a printed antenna method, or the like. An IC is connected to this antenna by a welding method or the like. Further, the IC inlet composed of the IC chip (21), the antenna coil (22), and the antenna sheet substrate (20) has the thickness of the IC chip itself, the thickness of the antenna, the junction between the jumper wire and the antenna, and the antenna sheet base. Depending on the thickness of the material itself, the sheet is uneven. When this IC inlet is sandwiched between exterior base materials (30) and processed into a non-contact type information medium, it is desirable to eliminate these irregularities in appearance.
外装基材（３０）としては、例えば、ポリ塩化ビニル（ＰＶＣ）、テレフタル酸／グリコール／１，４シクロヘキサンジメタノール共重合体（ＰＥＴ−Ｇ）などだけではなく、多孔質熱可塑性基材を使用することが出来、このような材料は一般にインクジェットやオフセットなどに対する印刷適性を付与した樹脂シート又は合成紙として市販されている。特に、基材に多孔質熱可塑性基材を使用することで柔軟性のある非接触型情報媒体を形成することが可能となり、また、接着剤と良好な密着性を得ることが出来るため加工性に優れている。 As the exterior substrate (30), for example, not only polyvinyl chloride (PVC), terephthalic acid / glycol / 1,4 cyclohexanedimethanol copolymer (PET-G), but also a porous thermoplastic substrate is used. In general, such materials are commercially available as resin sheets or synthetic papers that have been provided with printability for inkjet and offset. In particular, by using a porous thermoplastic substrate as the substrate, it becomes possible to form a flexible non-contact type information medium, and it is possible to obtain good adhesion with an adhesive, so that workability is achieved. Is excellent.
上記多孔質熱可塑性基材を使用する場合、図３に示すように２枚の外装基材（３０）のそれぞれ内側にあたる部分に、あらかじめ熱可塑性の接着剤（３３）を塗布してから積層し、熱圧をかけることで接着させ、非接触型情報媒体（１０）を得る。ここで使用可能な熱可塑性の接着剤（３３）は、エチレン−酢酸ビニル共重合体系、エチレン−メタクリル酸共重合体系、ポリエステル系、アクリル系樹脂、ポリアミド系、ポリウレタン系、ポリオレフィン系など、一般的な各種熱可塑性の樹脂を使用することができる。これらの中でも、特に水分に強く、酸素や塩化物イオンの透過を抑制するような塗膜を形成する樹脂、また熱や湿度により劣化ぜず接着部分に剥がれを生じないものを使用する。これらの性能を両立させるために２種類以上の樹脂を混合したり、２層に塗工したりすることも可能である。また、後工程や作業性の面から、塗工が容易で、乾燥後のブロッキングが生じにくく、耐久性の高いものが使用に適する。例えば、エチレン−メタクリル酸共重合体系の水系エマルジョン接着剤にエポキシ系架橋剤を添加したものや、ポリオレフィン系、アクリル系の接着剤などをグラビアコーターで塗工するなどで好適な性能を得ることが出来る。一方、一般的にポリエステル系の接着剤は湿度による加水分解が生じる可能性があり、エチレン−酢酸ビニル共重合体系接着剤は経時劣化し易いので注意が必要である。また、上記の樹脂を使用してエマルジョンやディスパージョンにした水系のヒートシール剤を用いる場合には、それらのヒートシール剤自体がアンテナ等に悪影響を与えないかについても注意が必要である。 When the porous thermoplastic substrate is used, as shown in FIG. 3, the thermoplastic adhesive (33) is applied in advance to the inner portions of the two exterior substrates (30), and then laminated. Then, it is bonded by applying hot pressure to obtain a non-contact type information medium (10). The thermoplastic adhesive (33) that can be used here is an ethylene-vinyl acetate copolymer system, an ethylene-methacrylic acid copolymer system, a polyester system, an acrylic resin, a polyamide system, a polyurethane system, a polyolefin system, or the like. Various thermoplastic resins can be used. Among these, a resin that forms a coating film that is particularly resistant to moisture and suppresses permeation of oxygen and chloride ions, and a resin that does not deteriorate due to heat and humidity and does not peel off at the bonded portion are used. In order to achieve both of these performances, two or more kinds of resins can be mixed or applied to two layers. In addition, from the viewpoint of the post-process and workability, coating is easy, blocking after drying is less likely to occur, and highly durable ones are suitable for use. For example, it is possible to obtain suitable performance by coating an ethylene-methacrylic acid copolymer aqueous emulsion adhesive with an epoxy crosslinking agent, or applying a polyolefin or acrylic adhesive with a gravure coater. I can do it. On the other hand, in general, a polyester-based adhesive may be hydrolyzed by humidity, and an ethylene-vinyl acetate copolymer-based adhesive is likely to deteriorate over time, so care must be taken. In addition, when using an aqueous heat sealant that has been made into an emulsion or dispersion using the above-mentioned resin, it is necessary to pay attention to whether the heat sealant itself adversely affects the antenna or the like.
また、本発明の非接触型情報媒体付属冊子は、この非接触型情報媒体（１０）を表紙用部材（１１）と内貼り用紙（１２）との間に挟み込んで接着し、冊子形状に加工されたものである。非接触型情報媒体（１０）は内貼り用紙（１２）と接着剤（３１）によって接着されるが、この接着剤は作業性や環境の側面からも水系のエマルジョン接着剤を使用する場合が多く、また、実際には、これまで冊子を製造してきた設備を使用することも多い
ので、布と紙の貼り合わせ用としての接着剤が選ばれてきた。仮に非接触型情報媒体付属冊子に使用する非接触型情報媒体を、一般のＩＣカードに使われるような外装基材、例えばＰＶＣやＰＥＴ−Ｇを使用して作成した場合、既存の設備および接着剤で内貼り用紙を接着することはできない上、剛度が高いことによる問題が生じる。このような問題を解決するため、多孔質熱可塑性基材シートを外装用基材として使用することで、様々なタイプの接着剤と良好な密着性を示し、かつ、凹凸が無く、柔軟な非接触型情報媒体付冊子を作成することが出来る。
The booklet attached with the non-contact type information medium of the present invention is processed into a booklet shape by sandwiching and bonding the non-contact type information medium (10) between the cover member (11) and the inner sheet (12). It has been done. The non-contact type information medium (10) is adhered to the inner sheet (12) and the adhesive (31), and this adhesive often uses a water-based emulsion adhesive from the viewpoint of workability and environment. Also, in practice, the equipment that has been used to produce booklets is often used, and therefore, an adhesive for bonding cloth and paper has been selected. If a non-contact type information medium used for a booklet attached to a non-contact type information medium is created using an exterior base material such as PVC or PET-G used for general IC cards, existing equipment and adhesion In addition, it is not possible to bond the inner sheet with an agent, and there is a problem that the rigidity is high. In order to solve such problems, the use of a porous thermoplastic base sheet as a base material for exteriors shows various types of adhesives and good adhesion, and has no unevenness and is flexible. A booklet with contact information media can be created.
非接触型情報媒体（１０）と表紙用部材（１１）を接着する際には、体積変化の無い反応硬化型の接着剤を好適に用いることが出来る。仮に体積変化のある乾燥硬化型の接着剤を使用した場合、非接触型情報媒体の一部が凹んでいたとすると、接着剤の使用量が多くなるため乾燥時の体積減少が大きくなり、表紙用部材の外側に凹みが生じてしまうため外観上の問題となる。このような問題を解決するために体積変化の無い接着剤を使用することが望ましく、例えば、２液混合型エポキシ系接着剤、湿気硬化型シリコン系接着剤、１液硬化型ウレタン系接着剤、などが使用できる。また、エチレン‐酢酸ビニル共重合体系、エチレン‐メタクリル酸共重合体、ポリエステル系、ポリアミド系、ポリウレタン系、ポリオレフィン系など、各種のホットメルト接着剤なども使用可能である。 When bonding the non-contact type information medium (10) and the cover member (11), a reaction curing type adhesive without volume change can be suitably used. If a dry-curing adhesive with a volume change is used, and if a part of the non-contact type information medium is recessed, the amount of adhesive used increases and the volume decreases during drying. Since a dent will arise in the outer side of a member for use, it will become a problem in appearance. In order to solve such a problem, it is desirable to use an adhesive having no volume change. For example, a two-component mixed epoxy adhesive, a moisture-curable silicone adhesive, a one-component curable urethane adhesive, Etc. can be used. Various hot melt adhesives such as ethylene-vinyl acetate copolymer system, ethylene-methacrylic acid copolymer, polyester series, polyamide series, polyurethane series, polyolefin series and the like can also be used.
非接触型情報媒体付属冊子は、熱により偽変造されることがあるため、該非接触型情報媒体（１０）に偽変造防止機能層（機能性色材層）（４０）や偽変造防止機能層（接着剤層）（４１）を持たせることが望ましい。そこで、図４から図８に示すように、熱により光の吸収ピーク波長又は特定波長における吸光度が変化するような機能性色材を用いて該非接触型情報媒体の内貼り用紙（１２）、外装基材（３０）、表紙用部材（１１）、の少なくとも１つに層を設けて、偽変造防止機能層（４０）とする。または図９から図１０に示すように、内貼り用紙と非接触型情報媒体の間の接着剤層や非接触型情報媒体と表紙用部材の間の接着剤層に機能性色材を混合させることで、偽変造防止機能層（４１）とする。機能性色材層を用いる場合、印刷方法を用いることで、絵柄、パターン、文字など、用途に合わせて偽変造防止機能層（４０）を付与することが出来る。 Since the booklet attached to the non-contact information medium may be falsified by heat, the falsification preventing functional layer (functional color material layer) (40) or the falsification preventing functional layer is added to the non-contact information medium (10). It is desirable to have (adhesive layer) (41). Therefore, as shown in FIG. 4 to FIG. 8, the non-contact type information medium-attached sheet (12), exterior, using a functional color material whose light absorption peak wavelength or absorbance at a specific wavelength is changed by heat. A layer is provided on at least one of the substrate (30) and the cover member (11) to form a forgery / alteration preventing functional layer (40). Alternatively, as shown in FIGS. 9 to 10, a functional color material is mixed in the adhesive layer between the inner sheet and the non-contact type information medium or in the adhesive layer between the non-contact type information medium and the cover member. Thus, the forgery / alteration prevention functional layer (41) is obtained. When the functional color material layer is used, the forgery / alteration prevention functional layer (40) such as a pattern, a pattern, a character, or the like can be provided by using a printing method.
次に、真贋判定方法は２つに大別できる。１つは目視による判定方法で、図１１（ａ）と（ｂ）に示すように、偽変造防止機能層（４０）を加熱することで光の吸収ピーク波長又は特定波長による吸光度を変化させ、発色、消色、変色を現し、可視領域の反応に用いる。この方法を用いて真贋判定する場合は、非接触型情報媒体付属冊子の内貼り用紙（１２）上に偽変造防止機能層（４０）を設けることが必要である。図１１（ａ）は非接触型情報媒体付属冊子に加熱をして変造する前の状態を表した一例の図で、無色の機能性色材を用いて内貼り用紙上に文字を印刷し、偽変造防止機能層（４０）としたものであり、非接触型情報媒体付属冊子を加熱すると偽変造防止機能層に変化が現れ、例えば、図１１（ｂ）に示すように文字が着色（４２）するため、加熱前後の変化を目視によって真贋判定が行なえる。 Next, authentication methods can be roughly divided into two. One is a visual determination method, as shown in FIGS. 11 (a) and 11 (b), by changing the absorption peak wavelength of light or the absorbance due to a specific wavelength by heating the forgery / alteration prevention functional layer (40), Shows color development, decolorization, and discoloration and is used for reactions in the visible region. When authenticating using this method, it is necessary to provide a forgery / alteration prevention functional layer (40) on the inner-attached paper (12) of the booklet attached to the non-contact type information medium. FIG. 11 (a) is an example of a state before heating and modifying the booklet attached to the non-contact type information medium. Characters are printed on the inner sheet using a colorless functional color material. The forgery / alteration prevention functional layer (40) is formed. When the booklet attached to the non-contact information medium is heated, a change appears in the forgery / alteration prevention functional layer. For example, as shown in FIG. Therefore, it is possible to determine the authenticity of the change before and after heating.
また、真贋判定方法の、もう１つは機械による判定方法で、図１２（ａ）と（ｂ）に示すように、前記方法と同様に加熱することで偽変造防止機能層（４１）に発色、消色、変色の機能の発現をさせる。機械検知による偽変造防止機能層（４１）の機能性色材は赤外吸収をするものが適しており、非接触型情報媒体付属冊子の最外装ではなく、内側に機能を持たせることも可能である。図１２（ａ）は非接触型情報媒体付属冊子に加熱をして変造する前の状態を表した一例の図で、無色の機能性色材を混合した接着剤（４１）を表紙用部材（１１）と非接触型情報媒体（１０）との間に設け、偽変造防止機能層（４１）としたものである。非接触型情報媒体付属冊子を加熱すると偽変造防止機能層に変化が現れ、例えば、図１２（ｂ）に示すように偽変造防止機能層内の赤外吸収する機能性色材が着色（４３）し、赤外光を照射した際の吸光度に変化が生じるため、加熱前後の吸光度の変化を機械で検知することで真贋判定が行なえる。 Another method of authenticity determination is a mechanical determination method. As shown in FIGS. 12A and 12B, the forgery / alteration prevention functional layer 41 is colored by heating in the same manner as described above. To develop functions of decolorization and discoloration. The functional color material of the functional layer (41) for preventing forgery / alteration by machine detection is suitable to absorb infrared rays, and it is possible to have a function on the inner side of the booklet attached to the non-contact information medium. It is. FIG. 12 (a) is a diagram showing an example of a state before heating and transforming the booklet attached to the non-contact type information medium, and an adhesive (41) mixed with a colorless functional color material is applied to the cover member ( 11) and a non-contact type information medium (10), and a forgery / alteration prevention functional layer (41) is provided. When the booklet attached to the non-contact type information medium is heated, a change appears in the forgery / alteration prevention functional layer. For example, as shown in FIG. ), And a change occurs in the absorbance when irradiated with infrared light. Therefore, authenticity can be determined by detecting the change in absorbance before and after heating.
熱圧を用いて形成された非接触情報記録媒体を、熱で分離して偽変造を行なうためには、多くの場合において１００℃以上の熱を加える必要があるため、本発明において使用する機能性色材も１００℃以上で反応する必要がある。特に、ホットメルト接着剤に機能性色材を混ぜることで偽変造防止機能層（４１）を設けるときは、ホットメルト接着剤の溶融温度が８０℃から１３０℃程度であることから、１３０℃以上で反応する機能性色材を選択する必要がある。 The function used in the present invention is because it is necessary to apply heat of 100 ° C. or more in many cases in order to perform falsification by separating the non-contact information recording medium formed using hot pressure with heat. It is necessary to react the coloring material at 100 ° C. or higher. In particular, when providing the forgery / alteration preventing functional layer (41) by mixing a functional color material in the hot melt adhesive, the melting temperature of the hot melt adhesive is about 80 ° C to 130 ° C. It is necessary to select a functional color material that reacts with.
前記機能性色材の材料はロイコ染料のように一般的に感熱記録材料に用いられるものでよく、例えばフルオラン系化合物、トリアリールメタン系化合物、スピロピラン系化合物、ジフェニルメタン系化合物、チアジン系化合物、ラクタム系化合物、フルオレン系化合物、ベンゾイルフェノチアジン系化合物、ロイコオーラミン系化合物、トリフェニルメタン系化合物等が挙げられ、その中でも１００℃以上または１３０℃以上の熱をかけることで顕色剤と反応し光の吸収波長に変化を生じる材料が好適に使用可能である。また、本発明で使用する顕色剤は一般に感熱記録紙に用いられているものであればよく、例えば、フェーノール化合物、チオフェノール化合物、チオ尿素誘導体等が挙げられる。 The functional color material may be a material generally used for a heat-sensitive recording material such as a leuco dye, such as a fluorane compound, a triarylmethane compound, a spiropyran compound, a diphenylmethane compound, a thiazine compound, or a lactam. Compounds, fluorene compounds, benzoylphenothiazine compounds, leucooramine compounds, triphenylmethane compounds, etc. Among them, light reacts with the developer by applying heat of 100 ° C. or more or 130 ° C. or more. A material that causes a change in the absorption wavelength of can be suitably used. Further, the developer used in the present invention may be any developer generally used for thermal recording paper, and examples thereof include phenol compounds, thiophenol compounds, and thiourea derivatives.
以下に、本発明の具体的実施例について、図４（実施例１）、図５（実施例２）を参照して説明する。 Hereinafter, specific examples of the present invention will be described with reference to FIG. 4 (Example 1) and FIG. 5 (Example 2).
