Definitions
- Holograms can be classified into several types according to the recording pattern of interference fringes, but surface relief holograms and volume holograms are typical.
- the surface relief hologram is a hologram image recorded by forming a fine uneven pattern on the surface of the hologram layer.
- the volume hologram is a hologram image recorded by three-dimensionally providing interference fringes generated by light interference as fringes having different refractive indexes in the thickness direction.
- the volume hologram is a hologram image recorded by the difference in the refractive index of the material, it has the advantage that it is difficult to replicate compared to the surface relief hologram. It is expected to be used as a forgery prevention means.
- the thread hologram is formed on a part of the paper medium for the purpose of preventing forgery of the paper medium having property value such as securities. Since such a thread hologram is formed on only a part of the paper medium, a high anti-counterfeiting effect can be exhibited and design properties can be imparted to the paper medium. Widely used for paper media. Moreover, the forgery prevention performance can be further enhanced by using a volume hologram as the hologram.
- the paper medium on which the thread hologram is formed is usually manufactured by rolling a thread hologram sheet into the paper medium when making the paper medium.
- the thread hologram sheet is usually stretched mechanically under heating conditions. Since the above-described thread hologram sheet can withstand the above-described indentation process, it has high mechanical strength against tensile stress and shear stress under heating conditions, that is, a machine such as tensile stress or shear stress. Must be highly resistant to stress.
- Patent Document 1 as a volume hologram thread hologram sheet, the layer configuration of the thread volume hologram sheet is set to the first protective layer / volume hologram layer / second protective layer, so that the heating is performed under the heating condition. It is disclosed that high durability can be imparted.
- the volume hologram sheet for threads in Patent Document 1 has resistance to mechanical stresses such as tensile stress and shear stress to some extent under heating conditions, it requires two protective layers, so that the film thickness is large. Therefore, the paper medium in which the volume hologram sheet for thread is encased has a problem that it is difficult to obtain a paper medium having irregularities on the surface and a smooth surface. Therefore, a thin volume hologram sheet for threads excellent in resistance to mechanical stress such as tensile stress and shear stress under heating conditions is desired.
- a card with a hologram as described above is known.
- Patent Document 2 discloses a card in which a hologram is arranged between a core sheet and an oversheet. In such a card, since the oversheet is thicker than the hologram, it is possible to improve the problems caused by the steps due to the thickness of the volume hologram as described above.
- the core sheet on which the hologram is arranged and the oversheet are press-laminated and laminated and integrated under heating conditions.
- the hologram has a hologram layer formed on the substrate, the air contained in the hologram escapes during thermocompression, and foaming occurs between the substrate and the hologram layer.
- the layers peel.
- the base material and the hologram layer are displaced during thermocompression bonding. Therefore, the hologram needs to have high resistance to mechanical stress such as compression stress under heating conditions in order to withstand such a process.
- an embedding hologram sheet used when being embedded in a paper medium or embedded in a card medium is excellent in resistance to mechanical stress under a predetermined heating condition.
- the present invention has a volume hologram layer and a base material disposed on only one surface of the volume hologram layer using an adhesive means, and the peel strength of the volume hologram layer and the base material is Provided is a volume hologram sheet for embedding, characterized by being 25 gf / 25 mm or more.
- the peel strength of the volume hologram layer and the substrate is 25 gf / 25 mm or more, when manufacturing anti-counterfeit paper or a card using the volume hologram sheet for embedding under heating conditions.
- Mechanical stress such as tensile stress, shear stress or compressive stress that does not cause problems such as separation of volume hologram layer, foaming between volume hologram layer and substrate, displacement of volume hologram layer and substrate
- a volume hologram sheet for embedding having resistance to stress can be obtained.
- the volume hologram sheet for embedding can be made into a thin film, the surface of the paper medium or card can be used even when the paper is embedded in the paper medium or embedded in the card medium in the step of embedding. It can be smooth.
- the main component of the resin material used for the volume hologram layer is an acrylic resin material, and the base material is made of a polyester resin.
- Suitable for stress such as tensile stress, shear stress or compressive stress when manufacturing anti-counterfeit paper or card under heating condition by using volume hologram layer mainly composed of resin material and base material made of resin Mechanical strength can be imparted.
- the adhesive means is an adhesive layer
- the adhesive used for the adhesive layer is a curable adhesive.
- the embedding volume hologram sheet of the present invention is subjected to stress such as tensile stress, shear stress or compressive stress when manufacturing anti-counterfeit paper or card under heating conditions. It is possible to impart suitable resistance to mechanical stress such as.
- the adhesion means is preferably an easy adhesion treatment
- the easy adhesion treatment is preferably a chemical treatment using a primer agent.
- the embedding volume hologram sheet of the present invention can be used for producing anti-counterfeit paper or cards under heating conditions, such as stress such as tensile stress, shear stress, or compressive stress. It is possible to impart suitable resistance to mechanical stress.

Abstract
Description
そこで、加熱条件下における引っ張り応力や剪断応力などの機械的ストレスに対する耐性に優れた薄膜なスレッド用体積ホログラムシートが要望されている。
ホログラムシールを貼付する方法やホログラムを転写する方法は、簡便な方法であるが、ホログラムが剥がされて転用されるおそれがある。特に、体積ホログラムは、屈折率差が三次元的に配列されることによってホログラム像が記録されるものであるという性質上、表面レリーフホログラムと比較して厚くなる傾向にある。そのため、体積ホログラムの厚みによってカード表面に段差が生じ、意匠性が損なわれるとともに、ホログラムの剥離を容易とし偽造を誘引する可能性がある。
一方、ホログラムをカード媒体中に埋め込む方法の場合、ホログラムの剥離が困難であり、偽造を防ぐことができる。例えば特許文献2には、コアシートとオーバーシートとの間にホログラムが配置されたカードが開示されている。このようなカードにおいては、オーバーシートがホログラムよりも厚いため、上記のような体積ホログラムの厚みによる段差に起因する不具合を改善することができる。
また、本発明は、2枚のシートの間に、上述した埋め込み用体積ホログラムシートが配置されていることを特徴とするカードを提供する。
本発明によれば、上述した埋め込み用体積ホログラムシートが用いられていることから、製造に際しての問題がなく、かつ、高い偽造防止効果を発揮することが可能である。
本発明の埋め込み用体積ホログラムシートは、体積ホログラム層と、上記体積ホログラム層のいずれか一方の表面のみに接着手段を用いて配置された基材とを有し、上記体積ホログラム層および上記基材の剥離強度が25gf/25mm以上であることを特徴とするものである。
また、本発明においては、図1に示すように、接着手段として接着剤層3を用いる代わりに、図2に示すように、基材2の表面に易接着処理aを施すことにより、体積ホログラム層1および基材2が接着されて配置されていてもよい。また、本発明は、接着手段として接着剤層3を用いた場合、および易接着処理aを用いた場合のいずれも、体積ホログラム層1および基材2の剥離強度が25gf/25mm以上であることを特徴とするものである。
しかしながら、上記の層構成の体積ホログラムシートを実際に紙媒体に漉き込んだ場合は、上記体積ホログラムシートから体積ホログラム層が剥離してしまうことや、体積ホログラム層が剥離してしまうことによって体積ホログラムシートが加工に耐え得る程度の加熱条件下における引っ張り応力や剪断応力などの機械的ストレスに対する耐性を有さないことが分かった。この問題を解決するため、本発明者らは、鋭意検討の結果、上述した剥離強度の測定方法において、上記層構成の体積ホログラムシートの体積ホログラム層および基材の剥離強度が25gf/25mm以上であれば、加熱条件下において、上記層構成の体積ホログラムシートを用いて偽造防止用紙等を製造した場合に体積ホログラム層の剥離等の問題が生じないことを見出した。
また、上記の層構成の体積ホログラムシートを実際にカード媒体中に埋め込んだ場合は、基材とホログラム層との層間で発泡が生じて体積ホログラムシートから体積ホログラム層が剥離すること、基材とホログラム層とにズレが生じること、基材と体積ホログラム層との層間での発泡や基材とホログラム層とのズレによって体積ホログラムシートが加工に耐え得る程度の加熱条件下における圧縮応力などの機械的ストレスに対する耐性を有さないことが分かった。この問題を解決するため、本発明者らは、鋭意検討の結果、上述した剥離強度の測定方法において、上記層構成の体積ホログラムシートの体積ホログラム層および基材の剥離強度が25gf/25mm以上であれば、加熱条件下において、上記層構成の体積ホログラムシートを用いてカードを製造した場合にも、基材および体積ホログラム層の層間での発泡や基材および体積ホログラム層のズレ等の問題が生じないことを見出した。
本発明者らはこのような知見に基づいて、本発明を完成させるに至ったのである。
また、本発明の埋め込み用体積ホログラムシート(スレッド用体積ホログラムシート)は、体積ホログラム層のいずれか一方のみに、接着手段を用いて基材が配置されている構成を有することから、埋め込み用体積ホログラムシート(スレッド用体積ホログラムシート)を薄膜なものとすることができるため、漉き込み工程で紙媒体に漉き込んだ場合に、紙媒体の表面を平滑なものとすることが可能である。
また、本発明の埋め込み用体積ホログラムシートは、体積ホログラム層のいずれか一方のみに、接着手段を用いて基材が配置されている構成を有することから、埋め込み用体積ホログラムシートを薄膜なものとすることができるため、カード媒体中に埋め込んだ場合に、カードの表面を平滑なものとすることが可能である。
「加熱条件下における引っ張り応力や剪断応力などの機械的ストレスに対する耐性」とは、本発明の埋め込み用体積ホログラムシート(スレッド用体積ホログラムシート)を紙媒体に漉き込む際にかかる引っ張り応力や剪断応力により、上記スレッド用体積ホログラムシートの基材と体積ホログラム層の間で剥離が起こらず、それに起因する各層の破断やヨレやシワ等を起こさない性質を示すものである。
また、本発明における「加熱条件下における圧縮応力などの機械的ストレスに対する耐性」とは、本発明の埋め込み用体積ホログラムシート(カード用体積ホログラムシート)をカード媒体中に埋め込む際にかかる圧縮応力により、体積ホログラム層と基材の層間での発泡や体積ホログラム層と基材のズレ等を起こさない性質を示すものである。

また、製造された埋め込み用体積ホログラムシートについては、上記体積ホログラム層および基材の剥離強度を調べることにより、使用可能か否かの検査を行うことが可能となる。
まず、本発明における体積ホログラム層について説明する。本発明に用いられる体積ホログラム層は、体積ホログラムの原理により屈折率差が記録され、これにより光像を発現する機能を有するものである。
また、本発明に用いられる体積ホログラム層は、いずれか一方の表面に接着手段を用いて基材が配置されている構成を有するものである。
まず、本発明における体積ホログラム層に用いられる構成材料について説明する。
本発明に用いられる体積ホログラム層を構成する材料としては、体積ホログラムを記録することができ、かつ、上記体積ホログラム層のいずれか一方の表面のみに接着手段を用いて基材を配置することができ、上記体積ホログラム層および基材の剥離強度を所定の値とすることができるのであれば特に限定されるものではなく、一般的な体積ホログラム層に用いられる材料を任意に用いることができる。このような材料としては、例えば、銀塩材料、重クロム酸ゼラチン乳剤、光重合性樹脂、光架橋性樹脂等の公知の体積ホログラム記録材料が挙げることできるが、なかでも本発明においては、(a)樹脂材料、光重合可能な化合物、光重合開始剤および増感色素を含有する第1の感光材料、または、(b)カチオン重合性化合物、ラジカル重合性化合物、光ラジカル重合開始剤系および光カチオン重合開始剤系を含有する第2の感光材料を好適に用いることができる。
以下、このような第1の感光材料および第2の感光材料について順に説明する。
まず、上記第1の感光材料について説明する。上述したように第1の感光材料は樹脂材料、光重合可能な化合物、光重合開始剤および増感色素を含有するものである。
本発明に用いられる樹脂材料としては、上記体積ホログラム層および後述する基材の剥離強度が25gf/25mm以上となるような体積ホログラム層とすることができるものであれば特に限定されるものではない。このような体積ホログラム層に用いることが可能な樹脂材料としては、ポリ(メタ)アクリル酸エステルもしくはその部分加水分解物、ポリ酢酸ビニルもしくはその部分加水分解物、ポリビニルアルコールもしくはその部分アセタール化物、トリアセチルセルロース、ポリイソプレン、ポリブタジエン、ポリクロロプレン、ポリ塩化ビニル、ポリアリレート、塩素化ポリエチレン、塩素化ポリプロピレン、ポリ-N-ビニルカルバゾール又はその誘導体、ポリ-N-ビニルピロリドンもしくはその誘導体、スチレンと無水マレイン酸の共重合体もしくはその半エステル、または、アクリル酸、アクリル酸エステル、アクリルアミド、アクリロニトリル、エチレン、プロピレン、塩化ビニル、もしくは酢酸ビニル等の共重合可能なモノマー群の少なくとも1つを重合成分とする共重合体等を用いることができる。また、それらの樹脂を2種以上混合してもよい。本発明においては、上述した樹脂のなかでもアクリル系の樹脂を主成分として用いることが好ましい。また、アクリル系の樹脂のなかでも、特にポリメチルメタクリレート系の樹脂を主成分として用いることが好ましい。
上記光重合可能な化合物としては、後述するような1分子中に少なくとも1個のエチレン性不飽和結合を有する光重合、光架橋可能なモノマー、オリゴマー、プレポリマーおよびそれらの混合物を用いることができる。具体例としては、不飽和カルボン酸およびその塩、不飽和カルボン酸と脂肪族多価アルコール化合物とのエステル、不飽和カルボン酸と脂肪族多価アミン化合物とのアミド化合物等を挙げることができる。
また、上記不飽和カルボン酸と脂肪族多価アミン化合物とのアミドのモノマーの具体例としては、メチレンビスアクリルアミド、メチレンビスメタクリルアミド、1,6-ヘキサメチレンビスアクリルアミド、1,6-ヘキサメチレンビスメタクリルアミド等を挙げることができる。
本発明に用いられる光重合開始剤としては、例えば、1,3-ジ(t-ブチルジオキシカルボニル)ベンゾフェノン、3,3′,4,4′-テトラキス(t-ブチルジオキシカルボニル)ベンゾフェノン、N-フェニルグリシン、2,4,6-トリス(トリクロロメチル)-s-トリアジン、3-フェニル-5-イソオキサゾロン、2-メルカプトベンズイミダゾール、また、イミダゾール二量体類等を挙げることができる。なかでも本発明に用いられる光重合開始剤は、記録された体積ホログラムの安定化の観点から、ホログラム記録後に分解処理されるものが好ましい。例えば有機過酸化物系にあっては紫外線照射することにより容易に分解されるので好ましい。
本発明に用いられる増感色素としては、チオピリリウム塩系色素、メロシアニン系色素、キノリン系色素、スチリルキノリン系色素、ケトクマリン系色素、チオキサンテン系色素、キサンテン系色素、オキソノール系色素、シアニン染料、ローダミン染料、チオピリリウム塩系色素、ピリリウムイオン系色素、ジフェニルヨードニウムイオン系色素等を挙げることができる。
次に、本発明に用いられる第2の感光材料について説明する。上述したように第2の感光材料は、カチオン重合性化合物、ラジカル重合性化合物、光ラジカル重合開始剤系、および、カチオン重合開始剤系を含有するものである。
上記カチオン重合性化合物としては、ラジカル重合性化合物の重合が比較的低粘度の組成物中で行われることが好ましいという点から、室温で液状のものが好適に用いられる。このようなカチオン重合性化合物としては、例えば、ジグリセロールジエーテル、ペンタエリスリトールポリジグリシジルエーテル、1,4-ビス(2,3-エポキシプロポキシパーフルオロイソプロピル)シクロヘキサン、ソルビトールポリグリシジルエーテル、1,6-ヘキサンジオールグリシジルエーテル、ポリエチレングリコールジグリシジルエーテル、フェニルグリシジルエーテル等を挙げることができる。
上記ラジカル重合性化合物としては、分子中に少なくとも1つのエチレン性不飽和二重結合を有するものが好ましい。また、本発明に用いられるラジカル重合性化合物の平均屈折率は、上記カチオン重合性化合物の平均屈折率より大きいことが好ましく、なかでも0.02以上大きいことが好ましい。これは、ラジカル重合性化合物とカチオン重合性化合物との屈折率の差によって、体積ホログラムが形成されることによるものである。したがって、平均屈折率の差が上記値以下である場合には、屈折率変調が不十分となるからである。本発明に用いられるラジカル重合性化合物としては、例えば、アクリルアミド、メタクリルアミド、スチレン、2-ブロモスチレン、フェニルアクリレート、2-フェノキシエチルアクリレート、2,3-ナフタレンジカルボン酸(アクリロキシエチル)モノエステル、メチルフェノキシエチルアクリレート、ノニルフェノキシエチルアクリレート、β-アクリロキシエチルハイドロゲンフタレート等を挙げることができる。
本発明に用いられる光ラジカル重合開始剤系としては、体積ホログラムを記録する際に、第1露光によって活性ラジカルを生成し、該活性ラジカルがラジカル重合性化合物を重合させることができるものであれば特に限定されるものではない。また、一般に光を吸収する成分である増感剤と活性ラジカル発生化合物や酸発生化合物を組み合わせて用いてもよい。このような光ラジカル重合開始剤系における増感剤は可視レーザー光を吸収するために色素のような有色化合物が用いられる場合が多いが、無色透明ホログラムとする場合には、シアニン系色素の使用が好ましい。シアニン系色素は一般に光によって分解しやすいため、本発明における後露光、または室内光や太陽光の下に数時間から数日放置することでホログラム中の色素が分解されて可視域に吸収を持たなくなり、無色透明な体積ホログラムを得ることができるからである。
本発明に用いられる光カチオン重合開始剤系としては、体積ホログラムが記録される際の第1露光に対しては低感光性で、第1露光と異なる波長の光を照射する後露光に感光してブレンステッド酸あるいはルイス酸を発生し、カチオン重合性化合物を重合させるような開始剤系であれば特に限定されるものではない。なかでも本発明においては第1露光の間はカチオン重合性化合物を重合させないものが用いられることが特に好ましい。このような光カチオン重合開始剤系としては、例えばジアリールヨードニウム塩類、トリアリールスルホニウム塩類、鉄アレン錯体類等が挙げられる。ジアリールヨードニウム塩類で好ましいものとしては上述した光ラジカル重合開始剤系で示したヨードニウムのテトラフルオロボレート、ヘキサフルオロホスフェート、ヘキサフルオロアルセネート、ヘキサフルオロアンチモネートなどが挙げられる。トリアリールスルホニウム塩類で好ましいものとしては、トリフェニルスルホニウム、4-ターシャリーブチルトリフェニルスルホニウム等が挙げられる。
本発明の埋め込み用体積ホログラムシートは、紙媒体に漉き込んで用いられたり、カード媒体に埋め込んで用いられたりするため、本発明に用いられる体積ホログラム層の厚みは、後述する基材等に応じて、埋め込み用体積ホログラムシートの厚みを紙媒体に漉き込む又はカード媒体に埋め込むことが容易となる程度にできる範囲内であることが好ましい。具体的には、0.1μm~50μmの範囲内であることが好ましく、なかでも1μm~20μmの範囲内であることが好ましい。
本発明に用いられる基材は、上記体積ホログラム層のいずれか一方の表面のみに、接着手段を用いて配置されるものである。
上記樹脂からなる基材を用いることにより、加熱条件下において埋め込み用体積ホログラムシートを用いて偽造防止用紙やカード等を製造するに際して、好適な機械的強度を有する埋め込み用体積ホログラムシートとすることができる。
本発明に用いられる接着手段は、上記体積ホログラム層の一方の表面のみに上記基材を配置するために用いられるものである。
本発明に用いられる接着剤層は、上記体積ホログラム層および基材の剥離強度が25gf/25mm以上となるように接着させるために、上記体積ホログラム層および基材の間に形成されるものである。
なお、本発明においては、上記硬化性の接着剤としては、光硬化性接着剤および熱硬化性接着剤のいずれも用いることが可能である。
本発明に用いられる易接着処理としては、上記体積ホログラム層および基材の剥離強度が25gf/25mm以上となるように、上記体積ホログラム層および基材を接着させることができるものであれば、特に限定されるものではなく、例えば、プラズマ処理、コロナ放電処理、グロー放電処理、火炎処理等の物理的処理、或いは、クロム酸、シランカップリング剤、プライマー剤等を使用した化学的処理を挙げることができる。
本発明においては、なかでも、プライマー剤を用いた化学的処理であることが好ましい。上記プライマー剤は、基材フィルム製造時に処理されるものと、製造後の基材フィルム上に処理されるものと、いずれの場合も好適である。このようなプライマー剤を処理した基材フィルムとしては、一般に市販されているものを用いることができる。具体的には、例えば、東洋紡績(株)製の易接着層付PETフィルムA4100、T4100や、帝人デュポンフィルム(株)製のテイジン(登録商標)テトロン(登録商標)フィルムHPE、ユニチカ社(株)製のエンブレット(登録商標)S、PTM、PET、パナック(株)製の易接着材料AC-X、AC-L、AC-Wなどが挙げられる。また、製造後の基材フィルム上に処理するプライマー剤としては、体積ホログラム材料と密着する材料であれば良い。特に、アクリル系樹脂材料が好ましく、さらにポリメチルメタクリレート等のメタクリル系樹脂を主成分として密着性を向上させるガラス転移点の低い材料を添加剤として含むものなどが好ましい。また、アクリル系樹脂以外では、ポリウレタン系材料と硬化剤との混合物も、好適に用いることができる。これにより、本発明の埋め込み用体積ホログラムシートに、加熱条件下において偽造防止用紙やカード等を製造するに際して好適な機械的強度を付与することができるからである。
プライマー剤により処理された基材フィルムにおいて、プライマー剤が層として存在する場合には、その層の厚みは1μm以下であることが好ましい。
本発明の埋め込み用体積ホログラムシートとしては、上述した体積ホログラム層、基材、および接着手段をそれぞれ組み合わせることにより、所定の膜厚を有し、体積ホログラム層および基材の剥離強度を25gf/25mm以上となるようにすることができるのであれば特に限定されるものではない。本発明においては、上述した体積ホログラム層、基材、および接着手段の組み合わせとして以下の組み合わせを好適に用いることができる。
本発明の埋め込み用体積ホログラムシートは、上記体積ホログラム層および基材が上述した接着手段を用いて配置されているのであれば特に限定されるものではなく、必要な部材を適宜追加することが可能である。このような部材としては、例えば、本発明の体積ホログラムシートの最外層に配置されるヒートシール層を挙げることができる。
以下、ヒートシール層、着色層、紫外線防止層について説明する。
本発明においては、体積ホログラムシートの最外層にヒートシール層が配置されていてもよい。
ここで、ヒートシール層とは、所定の温度で溶融若しくは軟化する感熱接着剤である。例えば、本発明の埋め込み用体積ホログラムシートがスレッド用体積ホログラムシートである場合、上記ヒートシール層は、上記スレッド用体積ホログラムシートを用いて偽造防止用紙等を製造する際に用いられる抄紙機の乾燥ゾーンの温度で溶融若しくは軟化する感熱接着剤となる。また例えば、本発明の埋め込み用体積ホログラムシートがカード用体積ホログラムシートである場合、上記ヒートシール層は、熱圧着のプレスラミネート工程での温度で溶融もしくは軟化する感熱接着剤となる。
本発明においては、例えば図3に示すように、体積ホログラム層1の基材2側とは反対側の面に着色層5が配置されていてもよい。
同様に、本発明の埋め込み用体積ホログラムシートがカード用体積ホログラムシートである場合、着色層の色がカードの基本色となり、着色層の色と、カード面に施された色とを同調させるなど、デザインバリエーションが広がる。例えば、着色層の色を青とし、カード面の印刷は青を基調、あるいは寒色系の同系色にするなどである。
本発明においては、体積ホログラム層の基材側の面に紫外線防止層が配置されていてもよい。紫外線防止層は、日光下あるいは照明光源の下に長時間暴露された際に、ホログラム画像、着色層の色や画像が経時的に劣化するのを防ぐために設けられるものである。
なお、体積ホログラム層より基材側にある基材を含む全ての層の吸光度の合計は、以下のようにして測定することができる。すなわち、まず、体積ホログラムシートより体積ホログラム層を取り除く。次いで、その際に残留した基材を含むフィルムに膜厚方向に波長340nmの光を入射した場合の吸光度を測定する。吸光度Aとは、入射光の強度をIとして、フィルムを透過した光の強度をI’とすると、A=-log(I’/I)で求められる値である。吸光度の測定は、例えば日本分光株式会社製の顕微紫外可視近赤外分光光度計 MSV-350や、島津製作所株式会社製の紫外可視近赤外分光光度計UV-3100PC等を用いて測定することができる。
紫外線吸収剤としては、例えば、有機系紫外線吸収剤、無機系紫外線吸収剤を挙げることができる。有機系紫外線吸収剤としては、具体的に、サリシレート系、ベンゾフェノン系、ベンゾトリアゾール系、ベンゾエート系、置換アクリロニトリル系、ニッケルキレート系、ヒンダートアミン系サリチル酸系、ハイドロキノン系、トリアジン系等の紫外線吸収剤が挙げられる。また、無機系紫外線吸収剤としては、具体的に、酸化チタン、酸化亜鉛、酸化セリウム等の金属酸化物系微粒子を広く使用できる。
また、紫外線吸収剤は、紫外線吸収性基が側鎖に結合した紫外線吸収性樹脂であってもよい。紫外線吸収性基としては、上記の有機系紫外線吸収剤や無機系紫外線吸収剤の構造を有するものを挙げることができる。
このような紫外線吸収性樹脂の例としては、メタクリル酸メチルとベンゾフェノン系紫外線吸収剤との共重合体(BASFジャパン製UVA635L)、メタクリル酸メチルとベンゾトリアゾール系紫外線吸収剤との共重合体(新中村化学工業(株)製 バナレジンUVA-73A、大塚化学(株)製 PUVA50M-40TM、(株)ニッコー化学研究所製 NCI-700、NCI-900)等が挙げられるが、これらに限定されない。
紫外線吸収性モノマーとしては、例えば重合性の不飽和結合を持ったベンゾフェノン系の紫外線吸収性モノマーや、重合性の不飽和結合を持ったベンゾトリアゾール系の紫外線吸収性モノマーが挙げられる。重合性の不飽和結合を持ったベンゾフェノン系の紫外線吸収性モノマーは、例えば2-ヒドロキシ-4-(メタクリロイルオキシエトキシ)ベンゾフェノン、2-ヒドロキシ-4-アクリロイルオキシベンゾフェノン、2-ヒドロキシ-4-メタクリロイルオキシベンゾフェノン、2-ヒドロキシ-4-(2-アクリロイルオキシ)エトキシベンゾフェノン、2-ヒドロキシ-4-(2-メタクリロイルオキシ)エトキシベンゾフェノン等が挙げられる。重合性の不飽和結合を持ったベンゾトリアゾール系の紫外線吸収性モノマーは、例えば(2-[2′-ヒドロキシ-5′-(メタクリロイルオキシ)エチルフェニル]-2H-ベンゾトリアゾール、2[2′-ヒドロキシ-5′-(アクリロイルオキシ)フェニル]ベンゾトリアゾール、2-[2′-ヒドロキシ-5′-(メタクリロイルオキシ)フェニル]ベンゾトリアゾール、2-[2′-ヒドロキシ-3′-t-ブチル-5′-(メタクリロイルオキシ)フェニル]ベンゾトリアゾール、2-[2′-ヒドロキシ-5-メチル-3-ビニルフェニル]ベンゾトリアゾール等が挙げられるが、これらに限定されない。
紫外線吸収性モノマーと重合し得るモノマーあるいはオリゴマーやポリマーとしては、アクリル酸およびそのエステル、メタクリル酸およびそのエステル、アクリルアミド、メタクリルアミド、酢酸ビニル、ビニルスルフォン酸およびその塩、メタリルスルフォン酸およびその塩、スチレンスルフォン酸およびその塩など、またはその共重合体を挙げることができる。
本発明の埋め込み用体積ホログラムシートは、上記体積ホログラム層および基材の剥離強度が25gf/25mm以上であれば、好適に紙媒体に漉き込んだりカードに埋め込んだりすることができる。
本発明の偽造防止用紙は、上述した「A.埋め込み用体積ホログラムシート」を用いたことを特徴とするものである。
本発明のカードは、2枚のシートの間に、上述の「A.埋め込み用体積ホログラムシート」に記載の埋め込み用体積ホログラムシートが配置されていることを特徴とするものである。

本発明に用いられるコアシートは、通常、プラスチックシートで構成される。コアシートとしては、白色の不透明プラスチックシートで構成されるのが一般的であるが、これに限定されるものではない。コアシートを構成するプラスチックシートとしては、例えば、ポリ塩化ビニル、ポリビニルアルコール、ポリスルホン、ポリエチレンテレフタレート等のポリエステル、ポリアリレート、ポリカーボネート、ポリアミド、ポリイミド、セルロースジアセテート、セルローストリアセテート、ポリスチレン系、アクリル、ポリプロピレン、ポリエチレン、もしくはポリオレフィンビニルアルコール等のプラスチックを素材とするものを使用することができる。耐熱性が要求される場合には、非晶質ポリエステルのシートや、非晶質ポリエステルとポリカーボネートのブレンド樹脂のシートも用いることができる。
本発明に用いられるオーバーシートは、通常、プラスチックシートで構成される。オーバーシートとしては、無色透明のプラスチックシートで構成されるのが一般的であるが、これに限定されるものではない。ただし、オーバーシートは、有色であるか無色であるかは別として透明であることが好ましい。
オーバーシートを構成するプラスチックシートとしては、上記のコアシートを構成するプラスチックシートと同様とすることができる。
本発明においては、カードの名称やカードの番号等の文字や、絵柄等の情報が印刷されており印刷層が形成されていてもよく、また上記情報がエンボス加工されていてもよい。
本発明のカードが磁気カードである場合、磁気記録層が形成されていてもよい。磁気記録層としては、一般的なカードの磁気記録層と同様とすることができる。
本発明のカードの厚さとしては、コアシートやオーバーシートの材質によっても異なるが、通常、10μm~5mm程度である。磁気カードの場合、カードをISO規格に準拠したものとするには、カードの厚さは0.76mmである。また、通常のカードの場合、例えば、コアシートとして厚さ280μmの白色ポリ塩化ビニル(PVC)シートを用い、オーバーシートとして厚さ100μmの透明ポリ塩化ビニル(PVC)シートを用いて、コアシートを2枚重ね、その両側にそれぞれオーバーシートを重ねて、熱プレスなどにより積層する四層構成のカード(合計厚さ0.76mm)を用いるのが一般的である。
