[Prior Art] The technique disclosed in Patent Document 1 is known as an adhesive sheet for making forgery prevention which is difficult for others to distinguish, or a forgery preventing adhesive sheet which is difficult to tamper with. The adhesive sheet for preventing forgery disclosed in Patent Document 1 is formed of a transparent film substrate, a partially transparent transparent release agent layer formed on one side of the transparent film substrate, and a layer covering the fluorescent release agent layer. The transparent film substrate is composed of all the adhesive layers on one side. When the above-mentioned forgery prevention adhesive sheet attached to the adherend is peeled off by someone, peeling of the interface between the transparent film substrate and the transparent fluorescent release agent layer, and a transparent fluorescent release agent are caused. The adhesive layer on the peripheral portion of the layer is cut, and the transparent fluorescent release agent layer remains on the adherend. Therefore, since the fluorescent release agent layer remaining in the adherend can be fluorescently colored by irradiation with ultraviolet rays on the adherend, it is possible to determine whether or not the forgery prevention adhesive sheet has been falsified. CITATION LIST Patent Literature Patent Literature 1: JP-A-H11-38880 (Summary of the Invention) (Problem to be Solved by the Invention) 3 322900 201139603 The anti-make film has been made to prevent the use of forgery. Ingenious tampering = Forgery prevention with a higher degree of protection than in the past, it is necessary to develop a film for the prevention of forgery in view of the above-mentioned circumstances. ''', means for solving the problem) The adhesive sheet for preventing forgery of the present invention has a transparent film portion formed on a transparent film, and is suitable for the surface of the film. The invisible light absorbing layer formed entirely or partially on the inner surface, and the adhesive layer formed to cover the invisible light absorbing layer and corresponding to the entire transparent film substrate. (Effect of the Invention) The present invention can provide a forgery prevention of a miscellaneous film, and it is difficult for anyone else to distinguish this (forty) film for forgery prevention, which is more finely copied than in the past, and is tampered after being peeled off (four), forged, etc. At the time, this misconduct can be discerned. [Embodiment] Hereinafter, an adhesive sheet for preventing forgery according to an embodiment of the present invention will be described with reference to the drawings. [First Embodiment] As shown in Fig. 1, the forgery prevention adhesive sheet i of the first embodiment is composed of a transparent film substrate 11, an easily peelable layer 12, an invisible light absorbing layer 13, and an adhesive layer 14. . In other words, the forgery preventing adhesive sheet 1 is formed by sequentially forming the easily peelable layer 12, the invisible light absorbing layer 13, and the adhesive layer 14 on the inner surface of the transparent film substrate 11, and the adhesive layer 14 is attached to the adhesive layer 14 The attached body A is sealed. The easily peelable layer 12 is formed on a portion of the transparent film substrate 11, and the invisible light absorbing layer 13 and the adhesive layer 14 cover the easily peelable layer 12 and are formed on the transparent film substrate 11. Further, it is preferable that the surface of the adhesive layer of the outermost layer is provided with a release paper (not shown). Hereinafter, each layer constituting the forgery preventing adhesive sheet 1 of the first embodiment will be more specifically described. [Transparent film substrate] The transparent film substrate 11 is made of, for example, a polyester resin such as polyethylene terephthalate or polybutylene terephthalate, or a polyolefin resin such as polyethylene or polypropylene. The film is preferred. Further, as the transparent film substrate 11, a film of a thermoplastic resin such as an acrylic resin, a polystyrene resin, a polyvinyl chloride resin or a polyvinylidene chloride resin can be used. The transparent film substrate 11 may be unstretched, or may be uniaxially stretched or biaxially stretched, or may be a transparent transparent resin film or a ductile transparent synthetic resin film. Further, the transparent film substrate 11 may be a single film or a plurality of films of different kinds or the same type. The thickness of the transparent film substrate 11 is usually in the range of 10 to 200 # m. [Easily peelable layer] The easily peelable layer 12 is partially formed on the inner surface of the transparent film substrate 11 and can be peeled off from the transparent film substrate 11 or the invisible light absorbing layer 13. If the transparent film substrate 11 is peeled off, the peelable layer is easily peeled off. 12 has the adhesion from the transparent film substrate 5 322900 201139603 11 or the extent that the invisible light absorbing layer 13 is easily peeled off. The easy-to-separate layer 12 is formed by forming a specific character pattern such as a character/number/symbol/picture by a material containing a release agent and an ink. The easily peelable layer 12 can be formed by various means such as coating, blowing, printing, and the like. The release agent is selected from the group consisting of a silicone resin, an alkyd resin, a long-chain alkyl resin, a fluororesin, a cellulose resin, a melamine resin, an acrylic resin, a polyurethane resin, a polyester resin, and the like, and a transparent film substrate 11 The resin having an adhesion to the easily peelable layer is 300 g/25 mm or less. The ink can be colorless or colored. When the ink is colored, the easily peelable layer 12 is formed as a visually recognized message pattern, so that it is preferable to use a pigment ink having weather resistance. There is no particular limitation on the ratio of ink to release agent. The thickness of the easily peelable layer 12 is usually in the range of 〇·3 to 1 〇//{11. [Invisible Light Absorbing Layer] The invisible light absorbing layer 13 covers the easily peelable layer 12 and is laminated on the transparent film substrate 11. In this embodiment, the invisible light absorbing layer 13 is formed on the entire surface of the transparent film substrate 11. In other words, the invisible light absorbing layer 13 is formed by covering the entire surface of the easily peelable layer 12 and covering the entire inner surface of the transparent film substrate u. The invisible light absorbing layer 13 is formed by an infrared absorbing ink layer containing an anti-climate tin oxide (ant imonym-dope). Since the invisible light absorbing layer 13 is a nearly transparent pale white color, it is combined with a wide variety of pigments to exhibit a richly varied color, and is suitable for forming a background color without a pattern. In the present embodiment, the background color of the easily peelable layer 12 is formed by covering the entire inner surface of the transparent film substrate u. 322900 6 201139603 The invisible light absorbing layer 13 is preferably formed by an infrared ray-emitting fluorescer which emits ray light by absorbing infrared rays. Infrared luminescent phosphors have infrared-visible light-converting phosphors that emit infrared light (about 800 to about 12 〇〇 nm) and emit visible light (about 400 to about 800 nm), and infrared light (about 800 to about Any one of the embodiments may be applied if it is excited to emit a longer wavelength (about 980 to about 1020 nm). Infrared-visible conversion of the former Fluorescent agent, YF3: Yb+Er, YF3: Yb+Tm, BaFCl: Yb+Er, etc. Further, the latter infrared luminescent phosphor, such as LiNduYbo.^OK, LiBi〇_2Nd〇.7Yb〇.iP4〇i2. [Adhesive Layer] The adhesive layer 14 is formed corresponding to the entirety of the transparent thin base material 11. The adhesive layer is preferably transparent. The adhesive layer 14 is formed of, for example, a natural rubber type, a synthetic rubber type, an acrylic resin type, a polyvinyl ether resin type, an urethane resin type, a silicone resin type, or the like by any adhesive. Yes. The adhesive layer 14 may also be formulated with an adhesive-imparting agent, a filler, a softener, an ant, an antioxidant, a crosslinking agent, and the like. As the adhesion imparting agent, a rosin-based resin, a terpene phenol resin, an anthraquinone resin, an antholeamine (anilide#, a phenol (phen〇1) system, a phosphite system, a thioester system, etc.) can be used. The parent-linked agent system may be a ring gas system, an isocyanate (is〇cyanat〇) system, a metal s system, a bismuth aziridine, an aziridine system, etc. When the adhesive layer 14 is provided By various methods, for example, further prepared with an adhesive and a solvent as desired, or dispersed or emulsified in a suitable medium, this is applied by a roll coater, a knife coater, or a roll knife. 7 322900 201139603 After coating with a coater such as a cloth machine, an air knife coater, a die coater, a bar coater, a gravure coater, or a curtain coater, it is preferable to cover with a release paper. Properties and Peeling] As described above, the easily peelable layer 12 is provided so as to be peelable from the transparent film substrate Π or the invisible light absorbing layer 13. Therefore, since the easily peelable layer 12 is easily made from the transparent film substrate u or not Since the visible light absorbing layer 13 is peeled off, the forgery preventing adhesive sheet 1 is pulled up from the attached body A. In addition, the forgery preventing adhesive sheet 1 is easily broken. In other words, the adhesion between the layers of the easily peelable layer 12 and the transparent film substrate 11 or between the layers of the easily peelable layer 12 and the invisible light absorbing layer 13 is set. It is weaker than the adhesion between the transparent film substrate 11 and the layer of the invisible light absorbing layer 13 or between the layers of the invisible light absorbing layer 13 and the adhesive layer 14. Moreover, the easily peelable layer 12 and the transparent film substrate The relationship between the interlayers of U and the adhesion between the layers of the easily peelable layer 12 and the invisible light absorbing layer 13 may be equal or weak. When the surface of the adhesive layer 14 is provided with release paper (not shown) In the case where the release paper is removed, in order to prevent the easy-peelable layer 12 from being peeled off, the adhesion between the layers of the easily peelable layer 12 and the transparent film substrate 11 must be greater than the adhesion between the layers of the release paper and the adhesive layer. It is to be noted that the adhesion between the layers of the transparent film substrate u and the easily peelable layer 12 is smaller than the adhesion between the layers of the easily peelable layer 12 and the invisible light absorbing layer 13, and is smaller than the invisible light absorbing layer 13 by the spot adhesive layer 14. Interface of layers When the adhesive sheet 1 for the forgery prevention is peeled off from the adherend A, the substrate 11 is peeled off from the easily peelable layer 12, so the invisible light absorbing layer 13 is peeled off. And the adhesive layer 14 is broken and separated from the transparent film substrate η. As shown in Fig. 2, there is a (4) separation layer 与 2 and an irregularly broken message pattern on the attached body. The laminate of the invisible light absorbing layer 13 and the adhesive crucible 14 has an invisible light absorbing layer 13 and an adhesive layer 14 having a residual message pattern on the inner surface of the transparent film substrate η. Therefore, even if the forgery preventing adhesive sheet 1 is attached as it is, it is difficult to restore the irregularly detached information pattern of the invisible light absorbing layer to the original state, and it is possible to prevent falsification or misconduct such as falsification or reattachment. . The forgery preventing adhesive sheet 1 having the above-described configuration can be used as a forgery prevention for banknotes, valuable securities, various certificates, printed matter, edges, and drawings. Example: The falsification preventing adhesive sheet 剥离 is peeled off from the adherend A, and the _ and the improper simplification exchanged in the cartridge as the attached body A are attached, and the falsification preventing adhesive sheet i is attached again as it is. It can also be checked by the following inspection methods. If you make a fake and reattach, you can actually check this. First, the first inspection method is to observe whether the surface of the forgery preventing adhesive sheet is smooth or not, and it is possible to judge whether or not the forgery preventing adhesive sheet 1 is peeled off. As described above, the adhesive sheet for the forgery prevention is attached to the layered body of the invisible light absorbing layer 13 and the adhesive layer 14 which has been irregularly broken from the easily peelable layer 12 even after being peeled off from the adhered body A. It is difficult to return to the state before the withdrawal.

When the transparent film substrate u is peeled off, as described above, the invisible light absorbing layer 13 is irregularly cut. 'Even if the transparent film substrate u is pasted back as it is, the cutting line is also generated. Tiny gaps. Therefore, when the infrared ray-irradiation-preventing adhesive sheet is leaked from the gap of the cutting line in the direction of the adherend A by the infrared-sensing camera, the outline of the easily peelable layer 12 becomes a white line in the infrared-sensing camera. The image + therefore 'by the infrared-sensing camera, the infrared ray is forged to prevent the use of the adhesive sheet, and the image of the visible light absorbing layer 骑 can be ridden only by looking at the camera image, and the forgery preventing adhesive sheet i can be reliably determined to be attached. Peeling of body A. As described above, the invisible light absorbing layer 13 of the forgery preventing adhesive sheet of this embodiment is composed of an infrared ray-absorbing ink containing white ytterbium-doped tin oxide, so that the infrared absorbing layer is not conspicuous. Therefore, it is difficult to see through the above-mentioned second inspection method, and it is assumed that even if it is counterfeited, the falsification of the forgery prevention adhesive sheet 1 of 322900 10 201139603 can be surely confirmed by the above-described second inspection method. Therefore, it is possible to peel off the forgery preventing adhesive sheet i from the attached body. After the separation, the surface of the forged attachment preventing adhesive sheet is attached to the attached body A. In the adhesive sheet for preventing forgery of the present embodiment, the invisible light absorbing layer 13 is formed by the infrared absorbing ink, so that it is difficult to recognize it from the appearance, and it is not justified that the printing of the invisible light absorbing layer is not performed by using the infrared absorbing ink. Admiration. The counterfeit preventing adhesive sheet which is counterfeit or falsified is not visible to the image of the infrared sensor camera, and the information pattern of the invisible light absorbing layer becomes white. Therefore, it was found that the forgery prevention adhesive sheet 1 was peeled off and subjected to fraudulent behavior. Further, when the invisible light absorbing layer contains an infrared ray-emitting ray, as a third method, when the fluorescent light is emitted and the image is received by the infrared ray-sensing camera, the image is obtained by discriminating whether or not there is light. It is prevented whether or not the adhesive sheet 1 is peeled off. It is almost impossible to prevent the counterfeiting of the adhesive sheet 1 from being counterfeited in accordance with both the invisible light absorption and the glory illumination. Even if the falsification is performed by the visual inspection, the second inspection method and the third inspection method can be performed using one infrared sensor camera, so that the forgery can be accurately determined. In addition, in the other inspection method, the forgery prevention adhesive sheet 1 is peeled off, and the invisible body A is irradiated with invisible light, and the reflected light is received by the invisible light sensing camera to obtain an image, and the forgery prevention adhesion after peeling is performed. The inner surface of the sheet 1 is also illuminated with invisible light, and the reflected light is reflected by the invisible light. 11 322900 201139603 The image is taken by the camera. Then, by observing whether the two images obtained as described above are mutually shaded and (4) inverted or not, it is possible to determine whether or not to forge. [Second Embodiment] The forgerification preventing adhesive sheet u of the second embodiment is formed as follows in the third embodiment, and the easy-peelable layer 12 and the invisible light absorbing layer 13 are sequentially formed on the inner surface of the transparent film substrate u. See Syria (4) 15, (4) riding a donkey. In other words, the invisible light reflecting layer 15 is interposed between the invisible light absorbing layer 13 and the adhesive layer 14 of the forged anti-adhesive adhesive sheet 1 of the first embodiment. ★ Embodiment 2 is the same as Embodiment ,, and the easy-peeling layer 12 is formed on the transparent film base #11❾. The invisible light absorbing layer 13 completely covers the easily peelable layer 12, and unlike the information pattern of the easily peelable layer, a dichroic pattern is formed on the transparent film except for the edge portion 8 of the transparent film substrate U. The invisible light reflecting layer 15 is entirely covered with the invisible light absorbing layer 13 and covers part or all of the edge portion B of the transparent film substrate 11 so that the invisible light reflecting layer 15 becomes the background color of the invisible light absorbing layer η. The adhesive layer 14 is formed by covering the invisible light reflecting layer 15. Further, it is preferable to provide a release paper on the surface of the adhesive layer. The invisible light reflecting layer 15 may contain titanium oxide or vulcanize in the case of reflecting infrared rays.钡, or a white ink of a pigment such as oxidized stone eve. The same as in the first embodiment, the interlayer of the easily peelable layer 12 and the transparent film substrate u or the layer between the easily peelable layer 12 and the invisible light absorbing layer 13 322900 12 201139603 The nature is set to be weaker than the adhesion between the other layers. The forgery prevention adhesive sheet 1A, the pattern of the easy peeling layer 12, and the background pattern of the invisible light reflecting layer 15 can be visually recognized, The visible light > the pattern of the absorbing layer 13 is not visually identifiable. The falsification preventing adhesive sheet 1A can be applied to the first inspection method of the first embodiment. In other words, by observation When the surface of the pressure-sensitive adhesive sheet 1 is smoothed along the contour of the easily peelable layer 12, it is possible to determine whether or not the forgery prevention adhesive sheet 1 is peeled off from the adherend A. The second inspection method is applied to the forgery prevention adhesive sheet 1A. The invisible light reflecting layer 15 functions to reflect the infrared rays to make the outline of the invisible light absorbing layer 13 clear. The forgery preventing adhesive sheet 1A of this embodiment is configured such that the invisible light absorbing layer 13 is formed smaller than the transparent film substrate 11 The size of the easy-peelable layer 12 is covered and covers the entire exposed portion of the inner surface of the transparent film substrate 11. Therefore, the forgery preventing adhesive sheet 1A without the invisible light reflecting layer 15 of the first embodiment is attached. When attached to the adherend A having the surface property of reflecting infrared rays, when the forgery preventing adhesive sheet 1A is irradiated with infrared rays and photographed by an infrared-sensing camera, the infrared rays irradiated to the outside of the invisible light absorbing layer 13 are attached to the attached body A. Since the surface is reflected, the outside of the invisible light absorbing layer 13 is white, so that the pattern of the invisible light absorbing layer 13 is displayed as a silhouette. When the adherend A does not have the surface property of reflecting infrared rays, even if the forgery preventing the invisible light reflecting layer 15 is irradiated with infrared rays, there is no reflection from the outer side of the invisible light absorbing layer 13 by the forgery preventing sheet 13 322900 201139603 Further, since there is no reflected light from the invisible light absorbing layer 13, the pattern of the clear invisible light absorbing layer 13 cannot be captured by the infrared sensor, and the outline of the forgery preventing adhesive sheet 1 cannot be imaged. When the forgery preventing adhesive sheet 1 having the invisible light reflecting layer 15 is attached to the adherend, the object A of the attachment target of the forgery preventing adhesive sheet 1 has the surface property of reflecting infrared rays, and the counterfeit prevention is prevented. When the infrared ray is irradiated with the adhesive sheet 1A and photographed by an infrared sensor, the pattern of the invisible light absorbing layer 13 is clearly displayed by the reflected light from the outside of the invisible light absorbing layer 13. Therefore, the forgery prevention adhesive sheet 1A can be confirmed more reliably, and further, it is possible to surely determine whether or not the forgery is made. In the same manner as in the first embodiment, the invisible light absorbing layer 13 is similar to the first embodiment, and is composed of an infrared ray-absorbing ink containing white ytterbium-doped tin oxide and an infrared ray-emitting luminescent agent. 3 check the method. In addition, when the forgery preventing adhesive sheet 1A is copied by a color photocopier, the invisible light reflecting layer 15 is also blackened and copied, so that it can be recognized as a counterfeit at a glance. [Other Embodiments] The present invention is not limited to the above-described embodiments, and various modifications and modifications are possible within the technical scope of the present invention without departing from the scope of the invention. (1) In the first embodiment, the invisible light absorbing layer 13, 14 322900 201139603 is limited to an ink that absorbs infrared rays (especially an ink that absorbs ink by infrared containing white doped tin oxide). The layer is described. However, it can also be used for ΙΤ0 or organic pigments having absorption in the infrared region. The organic coloring matter may, for example, be a polymethene system, a phthalocyanine system, a dithiol metallic complex salt, a naphthoquinone system, an anthraquinone system, an anthraquinone system, or an even group. A compound such as a nitrogen system or a triarylmethane system. (2) In the first embodiment, the invisible light absorbing layer 13 is particularly limited to an ink layer composed of an ink that absorbs infrared rays, and may be an ink layer that absorbs ultraviolet rays. In this case, as the second inspection method, the adhesive sheet 1 for preventing forgery is irradiated with ultraviolet rays, and the reflected light is received by the ultraviolet-sensing camera, and the image is observed to determine whether or not there is forgery. Examples of the ink layer that absorbs ultraviolet rays include, for example, diaminostilbene, quinazolone, anthraquinone, coumalin, oxazolyl, triazole, Carb carbazole, 0 唆, naphthalene dicarboxylic acid, imidazolone derivatives, or fluorescein, mineral oil, thioflavin (thiof lavin), blush (eosine), rhodamine, anthracene, terphenyl, and the like. When the non-visible light absorbing layer 13 is formed by ultraviolet absorbing ink, it may be further made to contain an ultraviolet luminescent phosphor. At this time, as the third inspection method, the fluorescent light is emitted, and the image is received by the ultraviolet-sensing camera to obtain an image, thereby confirming whether or not the forgery preventing adhesive sheet is peeled off. As in the first embodiment, the forgery of the forgery preventing adhesive sheet 1 is almost impossible, and it is almost impossible to prevent the forgery of both the ultraviolet absorbing and the ultraviolet ray illuminating. Even if the forgery cannot be discriminated by visual inspection, the second inspection method and the third inspection method can be performed using one ultraviolet-sensing camera, so that the forgery can be surely and accurately determined. (3) In the first embodiment, the "adhesive prevention adhesive sheet 1 is designed to be identifiable. However, when it is difficult to hide the design such as a passport or the like, the easy-peeling layer 12 and the invisible light absorption are absorbed. Layer 13 is formed to be transparent. (4) In the second embodiment, the configuration in which the invisible light absorbing layer 13 is formed so as to cover the entire easily peelable layer 12 is described. However, the invisible light absorbing layer 13 may be formed so as to cover the partially peelable layer 12. > (5) In the second embodiment, the case of forming the invisible light reflecting layer 15 that reflects infrared rays will be described. However, the invisible light reflecting layer 15' for reflecting ultraviolet rays may be made of gold, silver, copper, tin, or chromium. It is formed by vacuum evaporation of nickel or the like, money, and the like.
