Description

本発明は、赤外線照射によって赤外線を吸収し、かつ紫外線照射によって蛍光発色する偽造防止印刷層を備えた偽造防止帳票に関する。   The present invention relates to a forgery-preventing form provided with a forgery-preventing printing layer that absorbs infrared rays by irradiation with infrared rays and fluorescently develops color by irradiation with ultraviolet rays.

有価証券,証明書,登録証、或いはクレジットカード,キャッシュカード,その他の帳票にあって、偽造防止手段として、赤外線吸収顔料を含有するインキによって帳票面に偽造防止印刷層を形成したものや、紫外線蛍光発色顔料を含有するインキによって帳票面に偽造防止印刷層を形成したものが知られている。   For securities, certificates, registration certificates, credit cards, cash cards, and other forms, as a means of preventing counterfeiting, an anti-counterfeit printing layer is formed on the form surface with ink containing an infrared absorbing pigment, and ultraviolet rays An anti-counterfeit printing layer is formed on a form surface with an ink containing a fluorescent coloring pigment.

赤外線吸収顔料を含有するインキによって形成された偽造防止印刷層は、照射した赤外線の吸収を検出する検出装置によってのみその存在が認識可能であり、また、認識できても赤外線吸収顔料の入手が非常に困難で事実上偽造印刷をすることができないため、高いセキュリティを有するが、高価な検出装置を必要とし、認識を簡便に行えない難点がある。一方、紫外線蛍光発色顔料を含有するインキによって形成された偽造防止印刷層は、ブラックライトにより紫外線を照射すると蛍光発色し、目視によってその存在の認識を容易に行うことができるが、安価なブラックライトを用いて目視で認識し得るとともに、紫外線蛍光発色顔料の入手は容易で簡単に偽造印刷をすることができるため、セキュリティが低いものとなっている。   The presence of an anti-counterfeit printing layer formed with an ink containing an infrared absorbing pigment can be recognized only by a detection device that detects the absorption of irradiated infrared rays. However, since it is difficult to effectively perform counterfeit printing, it has high security, but it requires an expensive detection device and has a drawback that recognition cannot be performed easily. On the other hand, an anti-counterfeit printing layer formed with an ink containing an ultraviolet fluorescent coloring pigment, when irradiated with ultraviolet light by a black light, can develop a fluorescent color and can easily recognize its presence visually. The UV fluorescent coloring pigment is easy to obtain and can be easily counterfeit printed, so that the security is low.

そこで、赤外線照射によって赤外線を吸収し、かつ紫外線照射によって蛍光発色する偽造防止印刷層を形成してなる偽造防止用紙の構成が提案されている。   In view of this, there has been proposed an anti-counterfeit paper structure in which an anti-counterfeit printing layer that absorbs infrared rays by irradiation with infrared rays and forms a fluorescent color when irradiated with ultraviolet rays is formed.

かかる偽造防止用紙における偽造防止印刷層は、粉状物質からなる造粒物の表面に赤外線吸収顔料と紫外線蛍光発色顔料とを含有するコーティング層を備えた赤外線吸収粒子を製造し、この赤外線吸収粒子をビヒクルに混入してインキとした上で、該インキを用いて紙の表面に印刷することにより形成されている(特許文献1参照)。   The anti-counterfeit printing layer in such anti-counterfeit paper is produced by producing infrared absorbing particles having a coating layer containing an infrared absorbing pigment and an ultraviolet fluorescent coloring pigment on the surface of a granulated product made of a powdery substance. Is mixed with a vehicle to form an ink, and the ink is used to print on the surface of the paper (see Patent Document 1).

このように形成された偽造防止印刷層にあっては、赤外線照射時に赤外線吸収顔料が赤外線を吸収するため、これを検出装置で検出することができる一方、紫外線照射時には紫外線蛍光発色顔料が蛍光発色するため、これを目視で確認することができる。これにより、赤外線照射と紫外線照射の二重チェックを行うことができ、赤外線吸収顔料の使用により生じる高いセキュリティと、紫外線蛍光発色顔料の使用により生じる認識の容易性を兼備したものとなっている。
特開2003−129396号公報
In the anti-counterfeit printing layer formed in this way, the infrared absorbing pigment absorbs infrared rays when irradiated with infrared rays, and this can be detected by a detection device. Therefore, this can be confirmed visually. Thereby, double check of infrared irradiation and ultraviolet irradiation can be performed, and both high security generated by using the infrared absorbing pigment and ease of recognition generated by using the ultraviolet fluorescent coloring pigment are combined.

ところで、赤外線吸収顔料及び紫外線蛍光発色顔料には多数の種類があり、個々の顔料の可視光下で目視される色や、赤外線吸収作用或いは蛍光発色作用に差があるため、インキに含有させる赤外線吸収顔料及び紫外線蛍光発色顔料の種類及び量と、印刷時におけるインキの盛り量とによって、可視光下で目視される偽造防止印刷層の色濃度や、赤外線吸収作用或いは蛍光発色作用が変動する。ここで、上述したような造粒物の表面に赤外線吸収顔料と紫外線蛍光発色顔料とを含有するコーティング層を備えた赤外線吸収粒子をビヒクルに混入してインキを作る場合、該赤外線吸収粒子には、既に予め定められた種類の赤外線吸収顔料と紫外線蛍光発色顔料とが所定の配合比率でコーティング層に含有されていることにより、夫々の顔料の種類及び含有量の調整ができず、機械読み取りに必要な赤外線吸収作用としての赤外線吸収量や、紫外線照射時における蛍光発色作用としての蛍光発色の色及び強さが任意に変えられないという問題点がある。また、印刷時におけるインキの盛り量を変えることにより、可視光下で目視される偽造防止印刷層の色濃度や、前記赤外線吸収作用或いは蛍光発色作用をある程度調整することはできるが、印刷には適正なインキの盛り量があるため、偽造防止印刷層に付与する赤外線吸収作用或いは蛍光発色作用の作用レベルによっては対応できない場合もある。また、従来構成にあっては、粉状物質からなる造粒物の表面に赤外線吸収顔料と紫外線蛍光発色顔料とを含有するコーティング層を備えた特殊な粒子を製造する必要があるため、インキの製造コストが高くなるという問題点もあった。   By the way, there are many types of infrared absorbing pigments and ultraviolet fluorescent coloring pigments, and there is a difference in the color of each pigment that can be seen under visible light, infrared absorbing action or fluorescent coloring action. Depending on the type and amount of the absorbing pigment and the ultraviolet fluorescent coloring pigment and the amount of ink in printing, the color density of the forgery-preventing printing layer viewed under visible light, the infrared absorbing function, or the fluorescent coloring function varies. Here, in the case where an infrared absorbing particle having a coating layer containing an infrared absorbing pigment and an ultraviolet fluorescent coloring pigment on the surface of the granulated material as described above is mixed into a vehicle to form an ink, the infrared absorbing particle includes Because the coating layer contains a predetermined type of infrared absorbing pigment and ultraviolet fluorescent coloring pigment in a predetermined blending ratio, the type and content of each pigment cannot be adjusted, and machine reading is possible. There is a problem that the amount of infrared absorption as a necessary infrared absorption function and the color and intensity of fluorescence color development as a fluorescence color development function during ultraviolet irradiation cannot be changed arbitrarily. In addition, by changing the amount of ink deposited during printing, the color density of the anti-counterfeit printing layer viewed under visible light, the infrared absorption effect or the fluorescence coloring effect can be adjusted to some extent. Since there is an appropriate amount of ink, it may not be possible depending on the action level of the infrared ray absorbing action or fluorescence coloring action imparted to the forgery-preventing printing layer. In addition, in the conventional configuration, it is necessary to manufacture special particles having a coating layer containing an infrared absorbing pigment and an ultraviolet fluorescent coloring pigment on the surface of a granulated product made of a powdery substance. There was also a problem that the manufacturing cost was high.

本発明は、かかる従来の問題点を解消し得る偽造防止印刷層を備えた偽造防止帳票を提供することを目的とするものである。   An object of the present invention is to provide an anti-counterfeit form provided with an anti-counterfeit printing layer that can solve such conventional problems.

本発明は、帳票基材の外表面に、ビヒクルに赤外線吸収顔料と紫外線蛍光発色顔料とが混入されたインキを用いて印刷した偽造防止印刷層が形成されていることを特徴とする偽造防止帳票である。   The present invention relates to a forgery-preventing form characterized in that an anti-counterfeit printing layer is formed on the outer surface of a form base material by using an ink in which an infrared absorbing pigment and an ultraviolet fluorescent coloring pigment are mixed in a vehicle. It is.

本発明にかかる偽造防止帳票にあって、可視光下で目視される色と、紫外線照射時における紫外線蛍光発色顔料の蛍光発色の色とが異なる偽造防止印刷層を備えている構成が提案される。   In the anti-counterfeiting form according to the present invention, a configuration is proposed that includes a forgery-preventing printing layer in which the color visually observed under visible light is different from the fluorescent coloring color of the ultraviolet fluorescent coloring pigment during ultraviolet irradiation. .

また、上記偽造防止印刷層の着色手段として、赤外線吸収顔料及び紫外線蛍光発色顔料が可視光下で透明であり、ビヒクルに混入した可視光下で目視可能な有色顔料により偽造防止印刷層を形成するインキを着色する構成が提案される。   Further, as a coloring means for the anti-counterfeit printing layer, the anti-counterfeit printing layer is formed of a colored pigment that is transparent under visible light and visible with visible light mixed in the vehicle. A configuration for coloring the ink is proposed.

さらに、上記偽造防止印刷層の他の着色手段として、可視光下で目視可能な有色の赤外線吸収顔料又は可視光下で目視可能な有色の紫外線蛍光発色顔料により、偽造防止印刷層を形成するインキを着色する構成が提案される。   Further, as another coloring means for the anti-counterfeit printing layer, an ink for forming an anti-counterfeit print layer with a colored infrared absorbing pigment visible under visible light or a colored ultraviolet fluorescent coloring pigment visible under visible light A configuration for coloring is proposed.

本発明は、上述したように、帳票基材の外表面に、ビヒクルに赤外線吸収顔料と紫外線蛍光発色顔料とが混入されたインキを用いて印刷した偽造防止印刷層が形成されていることを特徴とする偽造防止帳票であるから、偽造防止印刷層を形成するインキに含有された赤外線吸収顔料が赤外線照射時に赤外線を吸収するため、これを検出装置で検出することができるとともに、同じく偽造防止印刷層を形成するインキに含有された紫外線蛍光発色顔料が紫外線照射時に蛍光発色するため、これを目視で確認することができる。これにより、赤外線照射と紫外線照射の二重チェックを行うことができ、赤外線吸収顔料の使用により生じる高いセキュリティと、紫外線蛍光発色顔料の使用により生じる認識の容易性を偽造防止帳票に兼備させることができる。ここで、インキ作成時に、ビヒクルに混入する赤外線吸収顔料と紫外線蛍光発色顔料の配合比率や、紫外線蛍光発色顔料の蛍光発色の色や強さは、偽造防止印刷層に付与する作用レベルに応じて任意に設定することができる。これにより、偽造防止印刷層は、赤外線吸収顔料または紫外線蛍光発色顔料自体の色や赤外線吸収作用若しくは蛍光発色作用に影響を受けることなく、適正なインキの盛り量で、優れた赤外線吸収作用及び紫外線蛍光発色作用を有するものとなり、また、紫外線照射時に所望の色及び強さで蛍光発色するものとなる。さらに、従来構成と異なり、粉状物質からなる造粒物の表面に赤外線吸収顔料と紫外線蛍光発色顔料とを含有するコーティング層を備えた特殊な粒子を製造する必要がないので、インキの製造コストが安くなり、該インキを用いた偽造防止印刷層の印刷により、偽造防止帳票の印刷コストを低減することができる。   As described above, the present invention is characterized in that an anti-counterfeit printing layer printed using an ink in which an infrared absorbing pigment and an ultraviolet fluorescent coloring pigment are mixed in a vehicle is formed on the outer surface of a form substrate. Because the infrared absorbing pigment contained in the ink that forms the anti-counterfeit printing layer absorbs infrared rays when irradiated with infrared rays, it can be detected by a detection device and is also anti-counterfeit printing. Since the ultraviolet fluorescent coloring pigment contained in the ink forming the layer develops a fluorescent color when irradiated with ultraviolet rays, this can be visually confirmed. This makes it possible to carry out a double check of infrared irradiation and ultraviolet irradiation, and to combine the high security generated by using an infrared absorbing pigment and the ease of recognition generated by using an ultraviolet fluorescent coloring pigment in an anti-counterfeiting form. it can. Here, the mixing ratio of the infrared absorbing pigment and the ultraviolet fluorescent coloring pigment mixed in the vehicle at the time of ink preparation, and the color and intensity of the fluorescent coloring of the ultraviolet fluorescent coloring pigment depend on the action level imparted to the anti-counterfeit printing layer. It can be set arbitrarily. As a result, the forgery-preventing printing layer is not affected by the color of the infrared absorbing pigment or the ultraviolet fluorescent coloring pigment itself, the infrared absorbing action, or the fluorescent coloring action. It has a fluorescence coloring action, and also emits fluorescence with a desired color and intensity when irradiated with ultraviolet rays. Furthermore, unlike the conventional configuration, it is not necessary to manufacture special particles with a coating layer containing an infrared absorbing pigment and an ultraviolet fluorescent coloring pigment on the surface of a granulated product made of a powdery substance, so that the ink manufacturing cost The printing cost of the anti-counterfeit form can be reduced by printing the anti-counterfeit printing layer using the ink.

上記偽造防止帳票にあって、可視光下で目視される色と、紫外線照射時における紫外線蛍光発色顔料の蛍光発色の色とが異なる偽造防止印刷層を備えてなる構成にあっては、可視光下の色と、蛍光発色の色とが異なることにより、その色の違いが明瞭となり、目視による識別を容易に行うことができる。   In the anti-counterfeiting form described above, if the structure is provided with a forgery-preventing printing layer in which the color visually observed under visible light and the fluorescent color of the ultraviolet fluorescent coloring pigment at the time of ultraviolet irradiation are different, the visible light When the lower color is different from the fluorescent color, the color difference becomes clear, and visual identification can be easily performed.

また、上記偽造防止印刷層の着色手段として、赤外線吸収顔料及び紫外線蛍光発色顔料が可視光下で透明であり、ビヒクルに混入した可視光下で目視可能な有色顔料により偽造防止印刷層を形成するインキを着色する構成にあっては、紫外線蛍光発色顔料の蛍光発色の色と相違する通常の有色顔料を使用してインキを容易に着色することができる。   Further, as a coloring means for the anti-counterfeit printing layer, the anti-counterfeit printing layer is formed of a colored pigment that is transparent under visible light and visible with visible light mixed in the vehicle. In the configuration for coloring the ink, the ink can be easily colored using a normal colored pigment that is different from the fluorescent coloring color of the ultraviolet fluorescent coloring pigment.

また、上記偽造防止印刷層の他の着色手段として、可視光下で目視可能な有色の赤外線吸収顔料又は可視光下で目視可能な有色の紫外線蛍光発色顔料により、偽造防止印刷層を形成するインキを着色する構成にあっては、通常の有色顔料を使用することなくインキの着色が可能であるため、インキの製造コストが安くなり、偽造防止印刷層の印刷コストをさらに低減することができる。   In addition, as another coloring means for the anti-counterfeit printing layer, an ink for forming an anti-counterfeit print layer with a colored infrared absorbing pigment visible under visible light or a colored ultraviolet fluorescent coloring pigment visible under visible light In the structure for coloring the ink, since the ink can be colored without using a normal colored pigment, the manufacturing cost of the ink is reduced, and the printing cost of the forgery-preventing printing layer can be further reduced.

本発明にかかる偽造防止帳票1は、図1,図2に示すように、帳票基材2の表面または裏面を構成する外表面3に、ビヒクルに赤外線吸収顔料と紫外線蛍光発色顔料とが混入されたインキを用いて印刷した偽造防止印刷層4が形成されている。   As shown in FIGS. 1 and 2, the forgery-preventing form 1 according to the present invention is mixed with an infrared absorbing pigment and an ultraviolet fluorescent coloring pigment in the vehicle on the outer surface 3 constituting the front or back surface of the form base 2. The anti-counterfeit printing layer 4 printed using the ink is formed.

前記帳票基材2には、紙,合成紙或は合成樹脂シート等が用いられる。偽造防止印刷層4の印刷方法としては、オフセット印刷,凸版印刷,グラビア印刷等の各種印刷方法が適用され、図示した帯状のパターンの他、図形,マーク,文字等の任意の形態で印刷することができる。   The form substrate 2 is made of paper, synthetic paper, synthetic resin sheet, or the like. Various printing methods such as offset printing, letterpress printing, and gravure printing are applied as a printing method for the forgery prevention printing layer 4, and printing is performed in an arbitrary form such as a figure, a mark, and a character in addition to the illustrated belt-like pattern. Can do.

偽造防止印刷層4の印刷に用いられるインキは、ビヒクルに赤外線吸収顔料10〜30重量%,紫外線蛍光発色顔料5〜40重量%,添加剤1〜10重量%を混入したインキであり、赤外線吸収顔料と紫外線蛍光発色顔料及び添加剤の混合比率は、使用する赤外線吸収顔料及び紫外線蛍光発色顔料の種類と、印刷時のインキの盛り量、及びインキに付与する特性に応じて任意に設定される。尚、添加剤には、酸化重合インキの場合、粘度調整剤,乾燥調整剤と、必要に応じて可視光下で目視可能な通常の有色顔料が含まれる。また、UV硬化型インキの場合、重合開始剤,重合禁止剤と、必要に応じて可視光下で目視可能な通常の有色顔料が含まれる。   The ink used for printing the anti-counterfeit printing layer 4 is an ink in which a vehicle is mixed with 10 to 30% by weight of an infrared absorbing pigment, 5 to 40% by weight of an ultraviolet fluorescent coloring pigment, and 1 to 10% by weight of an additive. The mixing ratio of the pigment, the ultraviolet fluorescent coloring pigment, and the additive is arbitrarily set according to the type of the infrared absorbing pigment and the ultraviolet fluorescent coloring pigment to be used, the amount of ink at the time of printing, and the characteristics to be imparted to the ink. . In the case of an oxidation polymerization ink, the additive includes a viscosity modifier, a drying modifier, and, if necessary, a normal colored pigment that can be visually observed under visible light. In the case of UV curable ink, a polymerization initiator, a polymerization inhibitor, and a normal colored pigment that can be visually observed under visible light are included as necessary.

赤外線吸収顔料には、可視光下で透明なものと、有色のものとがあり、公知の赤外線吸収顔料を使用することができる。例えば、可視光下で透明なものとしては、トリフェニルメタン系のレーキ顔料、錫ドープ酸化インジウム粉末等が用いられ得る。また、可視光下で有色のものとしては、黄,赤を呈するポリメチン系(シアニン系)のレーキ顔料、青を呈するフタロシアニン系の顔料、黄,赤,紫等を呈するナフトキノン系及びアントラキノン系のレーキ顔料、青,緑,紫等を呈するトリフェニルメタン系のレーキ顔料等が用いられ得る。   Infrared absorbing pigments include those that are transparent under visible light and those that are colored, and known infrared absorbing pigments can be used. For example, as a transparent material under visible light, a triphenylmethane-based lake pigment, tin-doped indium oxide powder, or the like can be used. Colors under visible light include polymethine (cyanine) lake pigments that exhibit yellow and red, phthalocyanine pigments that exhibit blue, naphthoquinone and anthraquinone lakes that exhibit yellow, red, purple, etc. Pigment, triphenylmethane-based lake pigments exhibiting blue, green, purple and the like can be used.

一方、紫外線蛍光発色顔料にも可視光下で透明なものと、有色のものとがあり、公知の紫外線蛍光発色顔料を使用することができる。例えば、可視光下で透明なものとしては、紫外線照射時に赤で蛍光発色するY2O3:Eu ,YVO4:Eu、緑で蛍光発色するZn2SiO4 ,MgAl11O19:Ce ,Tb、青で蛍光発色するSr2P2O7:Sn ,Sr4Al14O25:Eu 等の顔料が用いられ得る。また、可視光下で有色のものとしては、可視光下で黄を呈し、紫外線照射時に緑乃至黄緑で蛍光発色するブリリアントスルホフラビンFF、可視光下で黄を呈し、紫外線照射時に黄緑乃至黄で蛍光発色するベーシックイエローHG、可視光下で赤を呈し、紫外線照射時に黄乃至橙で蛍光発色するエオシン,ローダミン6G、可視光下でピンクを呈し、紫外線照射時に橙乃至赤で蛍光発色するローダミンB等の顔料が用いられ得る。 On the other hand, there are ultraviolet fluorescent coloring pigments that are transparent under visible light and colored pigments, and known ultraviolet fluorescent coloring pigments can be used. For example, transparent materials under visible light include Y 2 O 3 : Eu, YVO 4 : Eu, which emits fluorescence when irradiated with ultraviolet light, Zn 2 SiO 4 , MgAl 11 O 19 : Ce, Tb, which develops fluorescence with green. In addition, pigments such as Sr 2 P 2 O 7 : Sn and Sr 4 Al 14 O 25 : Eu that are fluorescent in blue can be used. In addition, as a colored substance under visible light, brilliant sulfoflavin FF that exhibits yellow under visible light and fluorescently develops green or yellow-green when irradiated with ultraviolet light, exhibits yellow under visible light, and exhibits yellow-green or green under ultraviolet light irradiation. Basic yellow HG that develops fluorescence under yellow, red under visible light, eosin, rhodamine 6G that develops fluorescence under yellow to orange when irradiated with ultraviolet light, pink under visible light, and orange or red when exposed to ultraviolet light Pigments such as rhodamine B can be used.

ここで、可視光下でともに透明な赤外線吸収顔料と紫外線蛍光発色顔料とを含有させた透明なインキを用いて偽造防止印刷層4を印刷した場合には、該偽造防止印刷層4は可視光下で目視不能となる。そして、この偽造防止印刷層4に赤外線を照射すると該偽造防止印刷層4が赤外線を吸収するため、これを検出装置で検出することができる。また、ブラックライトにより紫外線を照射すると偽造防止印刷層4が蛍光発色し、これを目視で確認できる。   Here, when the anti-counterfeit printing layer 4 is printed using a transparent ink containing both an infrared absorbing pigment and an ultraviolet fluorescent coloring pigment both transparent under visible light, the anti-counterfeit printing layer 4 is visible light. Underneath is invisible. And when this forgery prevention printing layer 4 is irradiated with infrared rays, the forgery prevention printing layer 4 absorbs infrared rays, and this can be detected by a detection device. Further, when the ultraviolet ray is irradiated with black light, the anti-counterfeit printing layer 4 develops a fluorescent color, which can be visually confirmed.

一方、可視光下でともに透明な赤外線吸収顔料と紫外線蛍光発色顔料とを含有させ、かつ可視光下で目視可能な有色顔料を含有させたインキを用いて偽造防止印刷層4を印刷した場合には、該偽造防止印刷層4は可視光下で目視可能となる。この有色顔料としては、ビヒクルに混入して印刷用のインキを着色する通常の顔料が使用され得る。このようにインキを着色する場合には、偽造防止印刷層4の可視光下で目視される色と、紫外線照射時における紫外線蛍光発色顔料の蛍光発色の色とを異ならせるようにする。このように偽造防止印刷層4の可視光下の色と、蛍光発色時の色とを異ならせると、その色の違いが明瞭となり、目視による識別が容易となる。また、偽造防止印刷層4の着色手段として、上述したように有色顔料を使用することにより、蛍光発色の色と相違する色にインキを容易に着色することができる。   On the other hand, when the anti-counterfeit printing layer 4 is printed using an ink that contains a transparent infrared absorbing pigment and an ultraviolet fluorescent coloring pigment that are both visible under visible light and a colored pigment that is visible under visible light. The anti-counterfeit printed layer 4 becomes visible under visible light. As the colored pigment, an ordinary pigment that is mixed in a vehicle and colors printing ink can be used. When the ink is colored in this way, the color of the anti-counterfeit printing layer 4 viewed under visible light is different from the color of the fluorescent coloring of the ultraviolet fluorescent coloring pigment during ultraviolet irradiation. Thus, if the color under visible light of the forgery-preventing printing layer 4 is different from the color at the time of fluorescent color development, the color difference becomes clear and visual identification becomes easy. Further, by using a colored pigment as the coloring means of the anti-counterfeit printing layer 4 as described above, the ink can be easily colored in a color different from the fluorescent color.

また、偽造防止印刷層4の他の着色手段として、可視光下で目視可能な有色の赤外線吸収顔料又は可視光下で目視可能な有色の紫外線蛍光発色顔料により、インキを着色することもできる。この場合には、通常の有色顔料を使用することなくインキの着色が可能であるため、インキの製造コストが安くなり、かかるインキを用いて印刷することで偽造防止印刷層4の印刷コストをさらに低減することができる。   In addition, as another coloring means of the anti-counterfeit printing layer 4, the ink can be colored with a colored infrared absorbing pigment that is visible under visible light or a colored ultraviolet fluorescent pigment that is visible under visible light. In this case, since the ink can be colored without using a normal colored pigment, the manufacturing cost of the ink is reduced, and the printing cost of the anti-counterfeit printing layer 4 can be further increased by printing using the ink. Can be reduced.

尚、偽造防止印刷層4の可視光下で目視される色と、紫外線照射時における紫外線蛍光発色顔料の蛍光発色の色とを同色にすることも可能であり、この場合には、紫外線蛍光発色顔料の蛍光発色の色と同色の有色顔料や、可視光下で同色を呈する赤外線吸収顔料又は紫外線蛍光発色顔料が用いられる。   It is also possible to make the color of the anti-counterfeit printing layer 4 visible under visible light the same as the color of the fluorescent color of the ultraviolet fluorescent coloring pigment when irradiated with ultraviolet light. A colored pigment having the same color as the fluorescent color of the pigment, an infrared absorbing pigment or an ultraviolet fluorescent color pigment exhibiting the same color under visible light is used.

このように、本発明にあっては、ビヒクルに混入する赤外線吸収顔料と紫外線蛍光発色顔料の配合比率や、紫外線蛍光発色顔料の蛍光発色の色や強さを、偽造防止印刷層に付与する作用レベルに応じて、インキ作成時に任意に設定することができるため、偽造防止印刷層4が優れた赤外線吸収作用及び紫外線蛍光発色作用を有するものとなり、また、紫外線照射時に所望の色及び強さで蛍光発色するものとなる。即ち、ビヒクルに混入する赤外線吸収顔料と紫外線蛍光発色顔料の種類や配合比率を変えることで、可視光下で目視される偽造防止印刷層4の色や濃度、赤外線吸収量、蛍光発色の色や強さを任意に調整することができる。さらに、従来構成と異なり、粉状物質からなる造粒物の表面に赤外線吸収顔料と紫外線蛍光発色顔料とを含有するコーティング層を備えた特殊な粒子を製造する必要がないので、インキの製造コストが安くなり、該インキを用いた偽造防止印刷層4の印刷により、偽造防止帳票1の印刷コストを低減することができる。   As described above, in the present invention, the blending ratio of the infrared absorbing pigment mixed with the vehicle and the ultraviolet fluorescent coloring pigment and the color and intensity of the fluorescent coloring of the ultraviolet fluorescent coloring pigment are imparted to the anti-counterfeit printing layer. Depending on the level, it can be set arbitrarily at the time of ink preparation, so the anti-counterfeiting printing layer 4 has excellent infrared absorption and ultraviolet fluorescent coloring, and has a desired color and intensity when irradiated with ultraviolet rays. Fluorescent color develops. That is, by changing the types and blending ratios of the infrared absorbing pigment and the ultraviolet fluorescent coloring pigment mixed in the vehicle, the color and density of the anti-counterfeit printing layer 4 visible under visible light, the infrared absorption amount, the fluorescent coloring color, The strength can be adjusted arbitrarily. Furthermore, unlike the conventional configuration, it is not necessary to manufacture special particles with a coating layer containing an infrared absorbing pigment and an ultraviolet fluorescent coloring pigment on the surface of a granulated product made of a powdery substance, so that the ink manufacturing cost The printing cost of the forgery prevention form 1 can be reduced by printing the forgery prevention printing layer 4 using the ink.
