Among these, FIGS. 1 to 2 are diagrams mainly for explaining the personal information display body, and FIGS. 3A to 3C are mainly diagrams for explaining a method for manufacturing the personal information display body. is there.

  As shown in FIG. 1, the personal information display 10 is a medium on which personal information is recorded. Specific applications of the personal information display 10 can include passports, driver's licenses, health insurance cards, cash cards, credit cards, employee cards, membership cards, and the like. Here, the personal information recorded on the personal information display 10 is information related to an individual, and is typically information related to a specific person who is given the personal information display 10. This personal information is not limited to information widely used by society in general, such as name, date of birth, gender, etc., but with specific organizations such as employee numbers and membership numbers (including credit card membership numbers) Information related to an individual used in relation to the personal information, information assigned to an individual for a certain period, and the like are also included. Therefore, from the issuer of the personal information display 10, the personal information recorded on the personal information display 10 is information that must be individually handled for each personal information display 10 given to each individual. Become.

  Such a personal information display body 10 is given to the specific person, for example, in order to prove the identity or qualification of the specific person. The issuer of the personal information display body 10 can manage the owner of the personal information display body 10 based on the information displayed on the personal information display body 10. As a specific example, a certain organization, for example, a company gives a personal information display body 10, for example, an employee ID card, as a medium for proving that the organization belongs to the organization, for example, an employee of the company. . Based on the owner's personal information displayed by the personal information display 10, the organization manages entry / exit in the premises and indoors, specifically entry / exit restrictions, entry / exit records, and attendance management Etc. can be performed. Therefore, for the personal information display 10, it is easy to authenticate the owner, in other words, it is easy to determine the authenticity of the personal information display 10, and imitation and falsification are difficult. Requested.

  As shown in FIG. 1, the personal information display body 10 has a display element for displaying the personal information of a specific person to which the personal information display body 10 should be given. In the example shown in FIG. 1, first to fifth display elements 41, 42, 43, 44, 45 are provided on the personal information display body 10. As shown in FIGS. 1 and 2, the personal information display 10 is formed in a card shape. The personal information display 10 includes a card-like display body 20 and a cover layer 34 stacked on one side of the display body 20. Further, in the illustrated example, an image receiving layer 28 is disposed between the display body 20 and the cover layer 34. The display elements 41 to 45 are located between the display body main body 20 and the cover layer 34 or inside the display body main body 20.

  In the example described here, the display body 20 before the display element is formed has a common configuration among all the personal information display bodies 10 to be issued. As shown in FIG. 2, the display body 20 includes a base material layer 22, a background print layer 24 laminated on one side of the base material layer 22, and a recording layer 26 laminated on one side of the background print layer 24. And have.

  The base material layer 22 can be produced by a known method using a known material used for a base material of an ID card, such as PET (polyethylene terephthalate), PVC (polyvinyl chloride), and PC (polycarbonate).

  The background print layer 24 is a layer on which a pattern common to the issued personal information display bodies 10, for example, a background pattern is printed. The background print layer 24 can also be produced by a known method using a known material.

  The recording layer 26 is a layer in which the second display element 42 is formed. In the illustrated example, the recording layer 26 is also a layer in which the third to fifth display elements 43 to 45 are formed. In the illustrated example, since the second to fifth display elements 42 to 45 are formed by laser engraving as will be described later, the recording layer 26 is a laser coloring layer.

  The laser coloring layer 26 is a layer that develops color when irradiated with laser light, and contains a laser coloring agent. Examples of the laser color former include leuco dyes such as fluorane, phenothiazine, spiropyran, triphenylmethphthalide, and rhodamine lactam. Specific examples of the leuco dye include 3,3-bis (p-dimethylaminophenyl) phthalide, 3,3-bis (p-dimethylaminophenyl) -6-dimethylaminophthalide, and 3,3-bis (p- Dimethylaminophenyl) -6-aminophthalide, 3,3-bis (p-dimethylaminophenyl) -6-nitrophthalide, 3,3-bis (p-dimethylaminophenyl) phthalide, 3,3-bis (3-dimethylamino) ) -7-methylfluorane, 3-diethylamino-7-chlorofuran, 3-diethylamino-6-chloro-7-methylfluorane, 3-diethylamino-7-anilinofluorane, 3-diethylamino-6-methyl- Examples include 7-anilinofluorane and 3-piperidino-6-methyl-7-anilinofluorane.

  The laser coloring layer 26 contains at least titanium oxide, a urethane resin, and silica in addition to the laser coloring agent. These contents are contained for the purpose of accelerating the color development of the laser color former and improving the film formability and adhesion of the laser color development layer 26.

  Further, the laser coloring layer 26 contains additives such as pigment dispersants, leveling agents, waxes, silane coupling agents, preservatives, rust inhibitors, plasticizers, flame retardants, and color developers as required. You may let them.

  In the example shown in FIG. 2, the laser coloring layer (recording layer) 26 is arranged on the display surface 10 s side of the personal information display body 10 with respect to the background print layer 24. Therefore, the laser coloring layer (recording layer) 26 may be colorless or colored in order to make the pattern printed on the background printing layer 24 visible, but is preferably transparent or translucent.

  In the present specification, “transparent or translucent” means that the transmittance of light in the visible light region is not 0%.

  The image receiving layer 28 is a layer in which the first display element 41 is formed. Specifically, the first display element 41 is formed on the image receiving layer 28 by the sublimation thermal transfer of the color material by the sublimation thermal transfer printing method. The image receiving layer 28 can be produced by a known method using a known material that easily receives a heat transferable coloring material of a sublimation dye. Examples of the material for producing the image receiving layer 28 include polyolefin resins such as polypropylene, halogenated resins such as polyvinyl chloride or polyvinylidene chloride, polyvinyl acetate, vinyl chloride-vinyl acetate polymers, ethylene-acetic acid. Vinyl resins such as vinyl copolymers or polyacrylates, polyester resins such as PET or PBT, polystyrene resins, polyamide resins, copolymers of olefins such as ethylene or propylene and other vinyl polymers, Examples thereof include cellulose resins such as ionomers and cellulose diastases, and polycarbonates.

  The image receiving layer 28 may be colorless or colored to make it possible to visually recognize the personal information displayed by the display elements 43 to 45 and the pattern printed on the background print layer 24, but is transparent or translucent.

  The first display element 41 may be formed by sublimation thermal transfer of a color material to the recording layer 26 by a sublimation type thermal transfer printing method. In this case, the personal information display body 10 may not have the image receiving layer 28.

  The cover layer 34 covers at least the display element 41 among the display elements 41 to 45 provided in the personal information display body 10 and protects the display element 41. The cover layer 34 can be produced by a known method using a known material used for a card body of an ID card, for example. The cover layer 34 may be colorless or colored in order to make it possible to visually recognize the personal information displayed by the display elements 41 to 45 and the pattern printed on the background print layer 24, but is transparent or translucent. The cover layer 34 is a layer that forms the outermost surface of the personal information display body 10 and preferably has scratch resistance and the like.

  Next, the display elements 41, 42, 43, 44, and 45 will be described in detail. As described above, the personal information display 10 includes display elements 41, 42, 43, 44, and 45 for displaying personal information of a specific person who should be the owner of the personal information display 10. 20 or inside the display body 20.

  In the example shown in FIG. 1, the first display element 41 and the fifth display element 45 display the upper body including the face as an image of a specific person. The second display element 42 and the third display element 43 display the identification number as symbol information such as letters and numbers. The fourth display element 44 displays the name, sex, date of birth as symbol information such as letters and numbers. When the personal information display 10 displays an image of the owner, particularly an image including a face as in the illustrated example, the authentication of the owner and the authenticity determination of the personal information display based on the authentication result are performed. It can be done easily and accurately.

  The image displayed by the fifth display element 45 is an image called a ghost image. The fifth display element 45 displays the same image as the image displayed by the first display element 41 with the same size or a different size. However, the first display element 41 and the fifth display element 45 are formed on the display body 20 by different methods. By providing the fifth display element 45 in the personal information display body 10 in addition to the first display element 41, the forgery prevention property of the personal information display body 10 can be effectively improved.

  First, the first display element 41 will be described. The first display element 41 is provided on one side of the recording layer 26 by printing. In particular, in the illustrated example, the first display element 41 is formed by sublimation thermal transfer of a color material to the image receiving layer 28 disposed between the recording layer 26 and the cover layer 34 by a sublimation type thermal transfer printing method. ing.

  The color material thermally transferred to the display body 20 can include various colors corresponding to the first display element 41 to be manufactured. In the personal information display 10 that displays personal information by a full-color image, four color materials of yellow, magenta, cyan, and black, or four color materials of red, green, blue, and black are applied to the image receiving layer 28. Thermal transfer will occur. As a result, between the display body 20 and the cover layer 34, one or more of four color materials of yellow, magenta, cyan, and black, or four color materials of red, green, blue, and black are used. One or more first display elements 41 are formed.

  Next, the second display element 42 will be described. As described above, in the personal information display 10 shown in FIG. 1, the second display element 42 displays the identification number as symbol information such as letters and numbers.

  As described above, in the example shown in FIG. 2, the recording layer 26 is a laser coloring layer, and the second display element 42 is formed at least inside the laser coloring layer 26 by a laser engraving method. . In other words, the second display element 42 is formed as a black layer along the scanning path of the laser light by irradiating the laser coloring layer with laser light in a wavelength range in which the laser coloring layer 26 exhibits sensitivity. The formation of the black layer is due to the fact that when the laser color forming layer 26 is irradiated with laser light, decomposition, vaporization, carbonization, etc. of the laser color former are induced.

  It should be noted that the personal information display body 10 includes a plurality of display elements that differ in at least one of the material and the forming method in this way, so that the forgery prevention property of the personal information display body 10 can be effectively enhanced.

  Further, the second display element 42 is formed in an area at least partially overlapping the first display element 41 along the normal direction of the personal information display surface 10 s of the personal information display body 10. As a result, even if the first display element 41 is removed from the personal information display body 10 by shaving or the like, the second display element 42 remains on the personal information display body 10. Therefore, by confirming the second display element 42 formed inside the laser coloring layer (recording layer) 26, the authenticity of the personal information display 10 can be determined. Note that the second display element 42 is not limited to the first display element 41 of the recording layer 26 when the first display element 41 is formed on one side of the recording layer 26 as described above. It is formed inside the area where the display element 41 is provided. Therefore, in this case as well, even if a part of the recording layer 26 (for example, a half on one side) is removed to remove the first display element 41, another part of the recording layer 26 (for example, a half on the other side) is removed. 2), the second display element 42 remains. Therefore, the authenticity of the personal information display 10 can be determined by checking the remaining second display element 42.

  In the illustrated example, the second display element 42 is formed so that the second display element 42 extends to a layer adjacent to the laser coloring layer (recording layer) 26. Such a second display element 42 includes the number of times of printing on the laser coloring layer 26 (the number of scanning times of the laser beam irradiated on the laser coloring layer 26) and / or the laser of the laser beam irradiated on the laser coloring layer 26. It can be formed by controlling the power [%], the Q switch frequency [Hz], and / or the scanning speed [mm / sec].

  In the illustrated example, the second display element 42 extends to the background print layer 24. Therefore, if not only the first display element 41 but also the second display element 42 is removed, the background print layer 24 is also removed. Thereby, falsification of the personal information display body 10 can be easily detected. Alternatively, since it is difficult to reproduce the destroyed background print layer 24, it is possible to effectively make the personal information display body 10 tampering.

  Further, in the illustrated example, the second display element 42 extends to the base material layer 22. In such a personal information display 10, a part of the second display element 42 remains on the base material layer 22 even if all the layers stacked on the base material layer 22 are removed. For this reason, in order to remove all the 2nd display elements 42, it is necessary to cut the base material layer 22. Thus, since the 2nd display element 42 is extended to the base material layer 22, the alteration of the personal information display body 10 can be made difficult effectively.

  In the illustrated example, the second display element 42 extends to the cover layer 34. Then, due to the second display element 42, irregularities corresponding to the personal information displayed by the second display element 42 are formed on the personal information display surface 10 s of the personal information display body 10. Such unevenness is removed together with the first display element 41 when the first display element 41 is removed and the personal information displayed by the first display element 41 is falsified. Therefore, it is possible to determine the authenticity of the personal information display body 10 only by confirming whether or not the personal information display body 10 is uneven, that is, by touching the personal information display body 10. Note that the unevenness formed on the display surface 10s cannot be easily reproduced by printing or the like. Thus, since the above-mentioned unevenness is provided on the outermost surface (display surface 10s) of the personal information display body 10, it is possible to easily determine the authenticity of the personal information display body 10 and to display the personal information. The tampering of the body 10 can be effectively made difficult.

  As described above, in the illustrated example, the second display element 42 is positioned on one side of the recording layer (laser coloring layer) 26 and from the display surface 10s that forms the outermost surface of the personal information display body 10, from the recording layer (laser). The color developing layer 26 extends continuously to the other side (more specifically, to the background printing layer 24 and the base material layer 22).

  Next, the third to fifth display elements 43 to 45 will be described. The third to fifth display elements 43 to 45 can be manufactured by various known methods. In the illustrated example, the third to fifth display elements 43 to 45 are formed inside the laser coloring layer 26 by a laser engraving method.

  When the third to fifth display elements 43 to 45 are formed in the laser coloring layer (recording layer) 26, the third to fifth display elements 43 to 45 are layers adjacent to the laser coloring layer (recording layer) 26. It does not have to extend to.

  As described above, since the second display element 42 is the same as any one of the third to fifth display elements 43 to 45 in the material and the forming method used for forming, the second display element 42 is added. Without using this material, it can be formed in the same step as the forming step of any of the third to fifth display elements 43 to 45. Of course, the 2nd display element 42 may be the same as any of the 3rd-5th display elements 43-45 in any one of the material used for formation, and a formation method. In this case, the second display element 42 can be formed without using an additional material or without an additional forming step.

  Of course, the 3rd-5th display elements 43-45 may differ from the 2nd display element 42 in all of the material used for formation, and a formation method. For example, the third to fifth display elements 43 to 45 may be formed in the same process as the formation of the first display element 42 by the same printing method as the first display element 42.

  In addition, in the personal information display 10 shown in FIG. 1, at least one of the third to fifth display elements 43 to 45 may be formed using a fluorescent material. Here, the fluorescent light emitting material is a material that exhibits sensitivity to light in a certain wavelength range and emits light when receiving light in the wavelength range. According to such a personal information display 10, personal information displayed by a display element formed using a fluorescent material is observed under special conditions. Under normal conditions, Personal information displayed by a display element formed using a fluorescent material can be prevented from being visually recognized.

  As an example, at least one of the third to fifth display elements 43 to 45 may be manufactured using a fluorescent material that emits visible light when irradiated with invisible light such as infrared rays or ultraviolet rays. Good. According to such a personal information display 10, since it contains personal information that cannot be displayed under normal conditions or is difficult to view, the forgery prevention property of the personal information display 10 can be greatly improved. . On the other hand, only the personal information displayed by the display element formed using the fluorescent light-emitting material is observed in a special environment where only the invisible light having the sensitivity of the fluorescent light-emitting material is irradiated. Thereby, the authentication of the owner and the authenticity determination of the personal information display body 10 can be easily and accurately performed also by the personal information image displayed by the display element formed using the fluorescent material. The display element using the fluorescent light emitting material can be formed by thermally transferring the fluorescent light emitting material to the recording layer 26 by a thermal transfer printing method or an ink jet printing method.

  Next, an example of a method for manufacturing the personal information display 10 described so far will be described.

  First, the display body 20 on which the image receiving layer 28 is laminated can be manufactured by a known method. Specifically, a laminate is prepared by laminating a plurality of sheet-like materials, each of which forms the base material layer 22, the background printing layer 24, the recording layer 26, and the image receiving layer 28 described above. . Thereafter, the obtained laminate is cut into a desired size to obtain the display body 20 in which the image receiving layer 28 is laminated (see FIG. 3A). It should be noted that the laminate, which is an intermediate when the display body 20 having the image receiving layer 28 laminated thereon, is formed in a size that allows a plurality of display bodies 20 having a desired size to be taken out. From the viewpoint of

  Next, as shown in FIG. 3B, the first display element 41 is provided on the recording layer 26 by printing. The first display element 41 is printed by, for example, the following method. That is, first, a thermal transfer sheet in which a color material is coated on a base sheet is prepared, and the thermal transfer sheet is disposed on the image receiving layer 28. Then, the thermal transfer sheet is heated and pressed toward the image receiving layer 28, and the color material of the thermal transfer sheet is sublimated and thermally transferred to the image receiving layer 28. In this way, the first display element 41 is formed in the image receiving layer 28.

  Next, as shown in FIG. 3C, the cover layer 34 is formed on the image receiving layer 28 on which the first display element 41 is formed. The cover layer 34 is formed by the following method, for example. That is, first, a thermal transfer sheet in which a material that forms the cover layer 34 is coated on a base sheet is prepared, and the thermal transfer sheet is placed on the image receiving layer 28 to which the color material has been transferred. Then, the thermal transfer sheet is heated and pressed toward the image receiving layer 28 to thermally transfer the material of the thermal transfer sheet to the image receiving layer 28. In this way, the cover layer 34 that covers the first display element 41 is formed.

  Next, as shown in FIG. 2, second to fifth display elements 42 to 45 are formed on the recording layer 26. Specifically, the second to fifth display elements 42 to 45 are recorded on the recording layer 26 by irradiating the laminated body in which the cover layer 34 is laminated with laser light from the cover layer 34 side. Can do.

  The laser beam used for the recording of the second to fifth display elements 42 to 45 may be appropriately selected according to the laser color former contained in the laser color development layer 26 and is not particularly limited. For example, laser light oscillated from an Nd: YAG laser (1064 nm), an Nd: YVO4 laser (1064 nm), or the like can be used.

  When the laser color layer 26 is irradiated with the laser light transmitted through the cover layer 34, decomposition, vaporization, carbonization and the like of the laser color former are induced, and the second to fifth display elements 42 along the laser light scanning path are induced. ˜45 are recorded in the recording layer 26 and are visually recognized.

  In the example shown in the figure, the second display element 42 is formed so that at least the second display element 42 extends to the background print layer 24 and the cover layer 34. The number of scans of the irradiated laser beam) and / or the laser power [%], Q switch frequency [Hz], and / or scan speed [mm / second] of the laser beam irradiated to the laser coloring layer 26 Controlled and implemented. For example, by increasing the number of scans of the laser beam when recording the second display element 42 rather than the number of scans of the laser beam when recording the third to fifth display elements 43 to 45, Of the five display elements 43 to 45, only the second display element 42 is formed so as to cover the background print layer 24, the base material layer 22, and the cover layer 34. Alternatively, by making the laser power of the laser light when recording the second display element 42 higher than the laser power of the laser light when recording the third to fifth display elements 43 to 45, Of the five display elements 43 to 45, only the second display element 42 is formed so as to cover the background print layer 24, the base material layer 22, and the cover layer 34.

  As described above, the personal information display 10 shown in FIG. 1 can be manufactured. However, the above manufacturing method is merely an example, and various modifications can be made. For example, in the manufacturing method described above, the first display element 41 is formed by sublimation thermal transfer, but may be formed by other printing methods such as a melt type thermal transfer method and an ink jet method. In this case, the image receiving layer 28 may not be laminated on the display body 20. Further, the third to fifth display elements 43 to 45 may be formed on the recording layer 26 by a material and a forming method similar to those used for forming the first display element 41.

  In the above, one embodiment of the personal information display 10 has been described with reference to FIGS. 1 to 3C, but the personal information display 10 described above is merely an example. For example, the first to fifth display elements 41 to 45 may display personal information different from the example described above.

The diffractive optical variable element cannot be easily duplicated by simple color copying or the like, and an advanced manufacturing technique is required for its manufacture. Therefore, the forgery prevention property of the personal information display body 10 can be effectively enhanced. As a typical example of the diffractive optical variable element, a hologram and a diffraction grating can be exemplified. The diffractive optical variable element composed of a hologram or a diffraction grating may be formed as a relief type or may be formed as a volume type. In the case of a relief-type diffractive optical variable element, since it is realized by forming irregularities on the optical element, it can be manufactured relatively easily. On the other hand, in the case of a volume type diffractive optical variable element, an extremely advanced manufacturing technique is required, so that the forgery prevention property can be improved. The diffractive optical variable element may be opaque, or may be transparent or translucent regardless of color or colorless. As a method of providing the diffractive optical variable element on the cover layer 34, the sheet-like diffractive optical variable element is transferred to the cover layer 34, or the sheet-like base material and the sheet-like diffraction transferred to the base material are used. It is conceivable to attach a hologram patch comprising an optical variable element to the cover layer 34.
