本発明の第１実施形態の偽造防止印刷物１は、図１、図２に示すとおりである。第１実施形態の平面図は、図１に示すように、印刷基材２面の所定領域にメジウムインキにより印刷された抜き文字印刷層11とパールインキ印刷層12からなる偽造防止印刷部10が形成されている。偽造防止印刷部10の積層構成は、図２に示すように、印刷基材２面上に、メジウムインキにより印刷された抜き文字印刷層11が形成され、抜き文字印刷層11の全面にパールインキ印刷層12が形成されている構成である。   The anti-counterfeit printed matter 1 of the first embodiment of the present invention is as shown in FIGS. As shown in FIG. 1, the plan view of the first embodiment includes an anti-counterfeit printing unit 10 composed of a letter print layer 11 and a pearl ink print layer 12 printed with a medium ink on a predetermined area of the printing substrate 2 surface. Is formed. As shown in FIG. 2, the anti-counterfeit printing unit 10 has a laminated structure in which a blank printed layer 11 printed with medium ink is formed on the surface of the printing substrate 2, and pearl ink is formed on the entire blank printed layer 11. In this configuration, the printing layer 12 is formed.

第１実施形態の偽造防止印刷物１では、メジウムインキにより印刷された抜き文字印刷層11とパールインキ印刷層12が積層されている構成であり、パールインキ印刷層12により抜き文字13による透かし印刷の効果が顕著になるので優れた偽造防止効果が得られる。   The anti-counterfeit printed matter 1 according to the first embodiment has a configuration in which a blank printed layer 11 printed with a medium ink and a pearl ink printed layer 12 are laminated. Since the effect becomes remarkable, an excellent anti-counterfeit effect can be obtained.

本発明の第２実施形態の偽造防止印刷物1'は図３、図４に示すとおりである。第２実施形態の平面図は、図３に示すように、印刷基材２面の所定領域に、紫外線ないしは赤外線の照射により蛍光発光する蛍光物質を含有するメジウムインキにより印刷された抜き文字印刷層11' とパールインキ印刷層12からなる偽造防止印刷部10' が形成されている。偽造防止印刷部10' の積層構成は、図４に示すように、印刷基材２面上に、紫外線ないしは赤外線の照射により蛍光発光する蛍光物質を含有するメジウムインキにより印刷された抜き文字印刷層11' が形成され、抜き文字印刷層11' の全面にパールインキ印刷層12が形成されている構成である。   The anti-counterfeit printed matter 1 ′ of the second embodiment of the present invention is as shown in FIGS. As shown in FIG. 3, the plan view of the second embodiment is a blank printed layer printed with a medium ink containing a fluorescent material that emits fluorescence when irradiated with ultraviolet rays or infrared rays in a predetermined region of the printing substrate 2 surface. An anti-counterfeit printing portion 10 ′ composed of 11 ′ and a pearl ink printing layer 12 is formed. As shown in FIG. 4, the anti-counterfeit printing unit 10 'has a layered structure in which a printed character printed layer is printed on the surface of the printing substrate 2 with a medium ink containing a fluorescent material that emits fluorescence when irradiated with ultraviolet rays or infrared rays. 11 'is formed, and the pearl ink printing layer 12 is formed on the entire surface of the blank character printing layer 11'.

第２実施形態の偽造防止印刷物1'では、紫外線ないしは赤外線の照射により蛍光発光する蛍光物質を含有するメジウムインキにより印刷された抜き文字印刷層11' とパールインキ印刷層12が積層されている構成であるので、紫外線ないしは赤外線の照射により、パールインキ印刷層12に抜き文字13がより鮮明に浮き出る状態となるので、より一層優れた偽造防止効果が得られるものである。   The anti-counterfeit printed matter 1 ′ of the second embodiment has a configuration in which a letter print layer 11 ′ printed with a medium ink containing a fluorescent substance that emits fluorescence when irradiated with ultraviolet rays or infrared rays and a pearl ink print layer 12 are laminated. As a result, the letters 13 are more clearly exposed in the pearl ink printing layer 12 by irradiation with ultraviolet rays or infrared rays, and thus a further excellent forgery prevention effect can be obtained.

第１、第２実施形態において、パールインキ印刷層12に有色インキを２０重量％以下の割合で添加することができる。有色インキを添加することにより、視認性を向上させ、また、その有色インキの添加量を２０重量％以下とすることで、パールインキの転色性を損なわせず偽造防止効果を向上させることができる。   In the first and second embodiments, colored ink can be added to the pearl ink printing layer 12 at a ratio of 20% by weight or less. By adding colored ink, visibility is improved, and by adding the colored ink to 20% by weight or less, the anti-counterfeiting effect can be improved without impairing the color transfer property of the pearl ink. it can.

実施形態の抜き文字印刷層11における抜き文字としては、実施形態のように比較的大きい文字を使用して抜き文字を形成してもよいし、小さい抜き文字を地紋状に印刷してもよく、抜き文字の形成は任意である。また、文字以外の特定のマークを配列した抜き文字としてもよい。   As the extracted character in the extracted character print layer 11 of the embodiment, a relatively large character may be used as in the embodiment, or a small extracted character may be printed in a background pattern, The formation of the blank character is arbitrary. Moreover, it is good also as a blank character which arranged the specific mark other than a character.

実施形態におけるパールインキ印刷層12、メジウムインキからなる抜き文字印刷層については、必要に応じて紫外線ないしは赤外線の照射により蛍光発光する蛍光物質を含有させてもよい。メジウムインキに紫外線ないしは赤外線の照射により蛍光発光する蛍光物質を含有させることで、カラーコピー等で複製することができないという偽造防止効果を付与することができる。   In the embodiment, the pearl ink printing layer 12 and the letter printed layer made of medium ink may contain a fluorescent material that emits fluorescence when irradiated with ultraviolet rays or infrared rays, if necessary. By incorporating a fluorescent material that emits fluorescence when irradiated with ultraviolet rays or infrared rays into the medium ink, an anti-counterfeit effect that cannot be replicated by color copying or the like can be imparted.

パールインキ印刷層12を形成するためのパールインキとしては、低屈折率の雲母に、透明で屈折率が２．０以上である酸化ケイ素、酸化チタン、酸化鉄などの金属酸化物の層を被覆した顔料を透明なビヒクル中に分散したものが使用できる。雲母と金属酸化物が組み合わされた時に、その屈折率の差が０．４より大きいことから、入射した白色光の反射量が多く、また同時に雲母と金属酸化物の界面で複屈折を起こすことから、高虹彩反射性となり、変色効果をより効果的に助長する働きをする。具体例としては、インフィニットカラー（資生堂製）イリオジン（メルク社製）等のパールインキ等が使用できる。   The pearl ink for forming the pearl ink printing layer 12 is coated with a layer of metal oxide such as silicon oxide, titanium oxide and iron oxide which is transparent and has a refractive index of 2.0 or more on mica having a low refractive index. A pigment dispersed in a transparent vehicle can be used. When mica and metal oxide are combined, the difference in refractive index is greater than 0.4, so the amount of incident white light is reflected, and at the same time, birefringence occurs at the interface between mica and metal oxide. Therefore, it becomes highly iris reflective and works to promote the discoloration effect more effectively. Specific examples include pearl inks such as Infinite Color (manufactured by Shiseido) and Iriodin (manufactured by Merck).

紫外線ないしは赤外線の照射により蛍光発光する蛍光物質としては、紫外線発光蛍光体又は赤外線発光蛍光体がある。紫外線発光蛍光体は紫外線により励起され、それよりも低いエネルギー準位に戻るときに発光するスペクトルのピークが青、緑、赤等の波長域にあるもので、例えば、Ｃａ2 Ｂ5 Ｏ9 Ｃｌ：Ｅｕ2+、ＣａＷＯ4 ＺｎＯ：Ｚｎ2 ＳｉＯ4 ：Ｍｎ、Ｙ2 Ｏ2 Ｓ：Ｅｕ、ＺｎＳ：Ａｇ、ＹＶＯ4 ：Ｅｕ、Ｙ2 Ｏ3 ：Ｅｕ、Ｇｄ2 Ｏ2 Ｓ：Ｔｂ、Ｌａ2 Ｏ2 Ｓ：Ｔｂ、Ｙ3 ＡＬ5 Ｏ12：Ｃｅ等があり、単体又はこれらの数種を選択し混合して使用する。これらの蛍光スペクトルはピークを青、緑、赤等の波長域以外にもつものであり、所望の蛍光スペクトルに応じて適宜選択することができる。インキ中の紫外線発光蛍光体の添加量は検出器の受光素子の蛍光の検知が可能となるようにすることが望ましい。 Examples of the fluorescent substance that emits fluorescence when irradiated with ultraviolet rays or infrared rays include an ultraviolet-emitting phosphor and an infrared-emitting phosphor. The ultraviolet light-emitting phosphor is excited by ultraviolet light, and has a spectrum peak emitted when returning to a lower energy level in a wavelength range such as blue, green, and red. For example, Ca 2 B 5 O 9 Cl : Eu 2+ , CaWO 4 ZnO: Zn 2 SiO 4 : Mn, Y 2 O 2 S: Eu, ZnS: Ag, YVO 4 : Eu, Y 2 O 3 : Eu, Gd 2 O 2 S: Tb, La 2 There are O 2 S: Tb, Y 3 AL 5 O 12 : Ce, etc., and a single substance or several of these are selected and mixed for use. These fluorescence spectra have peaks other than those in wavelength regions such as blue, green, and red, and can be appropriately selected according to a desired fluorescence spectrum. It is desirable that the amount of the ultraviolet light emitting phosphor added in the ink is such that the fluorescence of the light receiving element of the detector can be detected.

赤外線発光蛍光体は波長λ1 の励起光を受けて、波長λ2 の可視光を発光する特性を示し、λ1 ≠λ2 かつλ1 ＞λ2 なる性質を有するものとして、その組成は、例えば、ＹＦ3 ：Ｅｒ＋Ｙｂ、Ｙ3 ＯＣｌ7 ：Ｅｒ＋Ｙｂ、ＬａＬｎＦ4 ：Ｅｒ＋Ｙｂ（Ｌｎ＝Ｙ，Ｇｄ，Ｌａ）、ＢａＹ2 Ｆ8 ：Ｅｒ＋Ｙｂ、（ＰｂＦ2 −ＧｅＯ2 ）：Ｅｒ＋Ｙｂ、（ＰｂＦ2 −ＧｅＯ2 ）：Ｔｍ＋Ｙｂ等があり、いずれも励起光（λ1 ）８００〜１０００ｎｍの赤外線を受けて４５０ｎｍ〜６５０ｎｍに発光スペクトルの顕のピークを有する可視光線（λ2 ）を発光するものである。インキ中の赤外線発光蛍光体の添加量は検出器の受光素子の蛍光の検知が可能となるようにすることが望ましい。 Infrared emitting phosphor receives the excitation light having a wavelength lambda 1, shows a characteristic that emits visible light having a wavelength lambda 2, as having a λ 1 ≠ λ 2 cutlet λ 1> λ 2 becomes nature, its composition, For example, YF 3: Er + Yb, Y 3 OCl 7: Er + Yb, LaLnF 4: Er + Yb (Ln = Y, Gd, La), BaY 2 F 8: Er + Yb, (PbF 2 -GeO 2): Er + Yb, (PbF 2 -GeO 2 ): Tm + Yb, etc., all of which emits visible light (λ 2 ) having a visible peak of the emission spectrum at 450 nm to 650 nm upon receiving infrared light of excitation light (λ 1 ) of 800 to 1000 nm. It is desirable that the amount of the infrared light emitting phosphor added in the ink is such that the fluorescence of the light receiving element of the detector can be detected.
