Among these, FIGS. 1-10 is a figure for mainly explaining a personal information display body, and FIGS. 11-18 is mainly for demonstrating the manufacturing method and manufacturing apparatus of a personal information display body. FIG.

  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 in general society such as name, date of birth, gender, etc., but related to individuals used in connection with specific organizations such as employee numbers and membership numbers. Information, information assigned to individuals only 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 it is difficult to forge and tamper. 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, the first to third display elements 41, 42, 43 are provided on the personal information display body 10, and in the other examples shown in FIGS. 2 and 3, the first to fourth display elements are provided. Display elements 41, 45, 43, 44 are provided on the personal information display 10. As shown in FIGS. 1 and 4, 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 the display body 20. The display elements 41, 42, 43, 44, 45 are provided in the display body main body 20 and are positioned 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. 4, the display body 20 includes a first core layer 22 and a second core layer 23 that are stacked on each other and a first background stacked on both sides of the core layers 22 and 23. The print layer 25 and the second background print layer 26, and the first oversheet layer 28 and the second oversheet layer 29 laminated on both sides of the background print layers 25 and 26, respectively.

  The background print layers 25 and 26 have patterns common to the issued personal information display 10 such as a background pattern except for a special case such as a mode in which personal information is recorded by laser engraving described later. Is the printed layer. The oversheet layers 28 and 29 function as a protective layer. In particular, in the example shown in FIG. 4, the second oversheet layer 29 forms the outermost surface of the card-like personal information display body 10. The oversheet layers 28 and 29 protect the patterns printed on the background print layers 25 and 26. The oversheet layers 28 and 29 may be colorless or colored in order to make the patterns printed on the background print layers 25 and 26 visible, but are preferably transparent or translucent. Further, the cover layer 34 provided on the first oversheet layer 28 may be colorless or colored so that the personal information displayed by the display element and the pattern printed on the background print layer 25 can be visually recognized. It is translucent.

  Each layer and the cover layer 34 constituting the display body 20 can be produced by a known method using a known material used for a card body of an ID card, for example. However, the first oversheet layer 28 of the display body 20 that forms the surface on which the display elements 41, 42, 43, 44, 45 are formed has the display elements 41, 42 as shown in FIGS. 5 to 7. , 43, 44, 45 can take various forms. This point will be described later in correspondence with the description of the display elements 41, 42, 43, 44, 45.

  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. The cover layer 34 laminated on the first oversheet layer 28 of the display body 20 covers the display elements 41, 42, 43, 44, 45 and protects the display elements 41, 42, 43, 44, 45.

  In the example shown in FIG. 1, the first display element 41 and the second display element 42 display the upper body including the face as an image of a specific person. On the other hand, the third display element 43 displays the name, gender, date of birth, and identification number as character information. 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 personal authentication of the personal information display based on the authentication result are performed. It can be done easily and accurately.

  The first display element 41 is formed using the diffractive optical variable element 50. Here, the diffractive optically variable image device (DOVID) 50 is an element whose observation method, for example, brightness, color, or the like changes depending on the observation direction by using a diffraction phenomenon. As a typical example of the diffractive optical variable element 50, a hologram and a diffraction grating can be exemplified. The diffractive optical variable element 50 formed 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 the relief type diffractive optical variable element 50, 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 the volume type diffractive optical variable element 50, since a very advanced manufacturing technique is required, the forgery prevention property can be improved. The diffractive optical variable element 50 made of a hologram or a diffraction grating may be a transmission type or a reflection type. In the case of the reflective diffractive optical variable element 50, the core layers 22 and 23 and the background print layers 25 and 26 may not be formed transparently. The diffractive optical variable element 50 may be opaque, or may be transparent or translucent regardless of color or colorless.

  As a specific example, in the personal information display 10 shown in FIG. 10, the diffractive optical variable element 50 is provided on the first oversheet layer 28 (on the display body 20 through the bonding layer 56. The diffractive optical variable element 50 is configured as a relief-type computer-generated hologram, as shown in Fig. 10, the diffractive optical variable element 50 includes an uneven forming layer 52 having an uneven surface, and an uneven forming layer 52. The concavo-convex forming layer 52 is formed using, for example, a transparent resin, and the reflective layer 54 is formed on the concavo-convex surface of the concavo-convex forming layer 52. The reflective layer 54 can be formed using a metal-containing material having a refractive index different from that of the concavo-convex forming layer 52, such as titanium oxide, zinc sulfide, or tin oxide. 54 is opaque The point is not, it may be a transparent or semi-transparent.

  The first display element 41 displays personal information according to the arrangement pattern of the diffractive optical variable element 50. For example, by transferring the sheet-like diffractive optical variable element 50 in a desired arrangement pattern, the first display element 41 can display personal information grasped depending on the arrangement pattern of the diffractive optical variable element 50. it can. In other words, according to the personal information display 10 described here, the first display element 41 has the specific information of the specific person, typically, depending on the arrangement pattern of the diffractive optical variable element 50 that requires advanced manufacturing technology. The personal information of the owner of the personal information display body 10 is displayed. Thus, since the 1st display element 41 is formed using the diffractive optical variable element 50, forgery of the personal information display body 10 can be made difficult. On the other hand, since it is only necessary to display the personal information in the arrangement pattern of the diffractive optical variable element 50, it is not necessary to record the personal information on the diffractive optical variable element 50 itself, for example, as an uneven structure or interference fringes. Therefore, the personal information display 10 can be manufactured relatively easily and can exhibit excellent anti-counterfeiting properties.

  In addition, in the example shown in FIG. 1, the first display element 41 displays an image of a specific person who should become the owner of the personal information display body 10 by the arrangement pattern of the diffractive optical variable element 50. In general, in order to authenticate the owner of the personal information display body 10 based on the personal information display body 10, it is preferable that an image of the owner, particularly a face, is displayed on the personal information display body 10. When the image of the owner, in particular, the face is recorded on the personal information display body, the authentication of the owner and the authenticity determination of the personal information display body 10 based on the authentication result can be easily and accurately performed. . In particular, according to the example described here, the first display element 41 displays the image of the owner, particularly the face, by the arrangement pattern of the diffractive optical variable element 50 that requires advanced manufacturing techniques. Therefore, the personal information display body 10 that can be manufactured relatively easily can be provided with extremely excellent anti-counterfeiting properties, and the authentication of the owner using the personal information display body 10 and the personal information The authenticity determination of the display body 10 can be performed very easily and accurately.

  The diffractive optical variable element 50 itself has a pattern that does not display personal information. The pattern possessed by the diffractive optical variable element 50 itself is not limited to the one showing specific information or meaning the specific information, and is not particularly limited to the arrangement of figures, characters, symbols, marks and the like, the pattern, the pattern and the like. That is, the diffractive optical variable element 50 can display the personal information of a specific person according to the arrangement pattern, but the diffractive optical variable element 50 itself may display a pattern unrelated to the personal information. . Therefore, the pattern possessed by the diffractive optical variable element 50 itself is common to all the issued personal information display bodies 10 irrespective of the personal information to be displayed using the diffractive optical variable element 50. Can do. Thereby, the personal information display body 10 can be produced more easily.

  In addition, a minute concealment image can be included in a pattern irrelevant to the personal information displayed by the diffractive optical variable element 50 itself. In this case, it is possible to give a better anti-counterfeiting property to the personal information display 10 that can be manufactured relatively easily, and it is very easy and more accurate to determine the authenticity of the personal information display. It can be carried out.

  As shown in FIGS. 8 and 9, the diffractive optical variable element 50 has a gradation of binary or higher for each of the plurality of unit regions 48 defined on the surface on which the first display element 41 is to be provided. Can be arranged in In this case, the first display element 41 is formed as an aggregate of diffractive optical variable elements 50 arranged in the predetermined unit region 48. In the binary gradation, as shown in FIG. 8, the plurality of unit regions 48 are divided into two types: a region where the diffractive optical variable element 50 is disposed and a region where the diffractive optical variable element 50 is not disposed. Is done. In the example shown in FIG. 8, the surface on which the first display element 41 is to be provided, for example, the surface of the display body 20 in FIGS. 5 to 7 is divided into a matrix and arranged in a grid adjacent to each other. A plurality of unit regions 48 are defined. According to this embodiment, personal information can be displayed with excellent design by the first display element 41 using the diffractive optical variable element 50.

  Furthermore, as shown in FIG. 9, if the arrangement of the diffractive optical variable elements 50 in each unit region 48 is determined with three or more gradations greater than binary, an excellent design is achieved by the first display element 41. Personal information can be displayed by gender. For example, as shown in the figure, the first display element 41 can clearly display an image of the owner of the personal information display body, particularly a face image, with high resolution. As a result, the personal information display body 10 that can be manufactured relatively easily can be provided with a better anti-counterfeit property, and the personal information display body 10 can be authenticated and the personal information display can be performed. The authenticity determination of the body 10 can be performed very easily and more accurately. It should be noted that various known methods such as dithering can be employed as a method for realizing gradations having more than binary values.

  As an example, in the example shown in FIG. 9, the unit area 48 is divided into four sub-unit areas 49. Whether or not the diffractive optical variable element 50 is arranged is determined for each sub-unit region 49. As a result, as shown in FIG. 9, the plurality of unit regions 48 include a zero-stage region 48 a in which none of the four sub-unit regions 49 is provided with the diffractive optical variable element 50 and four sub-unit regions 49. The diffractive optical variable element 50 is provided in the one-stage region 48b in which the diffractive optical variable element 50 is provided only in one of the sub unit regions 49, and the two sub unit regions 49 of the four sub unit regions 49. The two-stage region 48c, the three-stage region 48d in which the diffractive optical variable element 50 is provided in three of the four subunit regions 49, and the four subunit regions 49 are diffracted. And a four-step region 48e where the optical variable element 50 is provided. In other words, in the example shown in FIG. 9, the first display element 41 is formed as a collection of diffractive optical variable elements 50 arranged in each of the plurality of unit regions 48 with a five-value area gradation. The personal information is displayed by the arrangement pattern of the aggregate of the diffractive optical variable elements 50 arranged in the area gradation.

  Note that the first display element 41 as an aggregate of the diffractive optical variable elements 50 arranged in the unit region 48 is obtained by attaching the diffractive optical variable element 50 formed in a sheet shape to the unit region 48 using an adhesive or the like. It can be produced by transferring. Typically, as will be described in detail later, the first display element 41 can be manufactured by thermal transfer using the thermal heads 62 and 67. In the example shown in FIG. 1, the arrangement of the diffractive optical variable elements 50 in each unit region 48 is controlled, and the human face is displayed by the controlled arrangement pattern of the diffractive optical variable elements 50. When the face is displayed as a so-called ghost image separately from the face displayed by the second display element 42 as in the example shown in FIG. 1, the size of the general ghost image in the ID card and In consideration of the number of pixels necessary for discriminating a human face with this size, the length of one side of the unit region 48 is preferably 20 μm or more and 300 μm or less. Transfer of the diffractive optical variable element 50 to the unit region 48 having such a size can be sufficiently realized by thermal transfer using a thermal head incorporated in a conventionally known thermal transfer printer.

  Next, the second display element 42 and the third display element 43 will be described. Similarly to the first display element 41, the second display element 42 and the third display element 43 also display personal information of a specific person who should own the personal information display body 10. As already described, in the personal information display 10 shown in FIG. 1, the third display element 43 displays the name, gender, date of birth, and identification number as character information. On the other hand, similarly to the first display element 41, the second display element 42 displays the upper body including the face of a specific person who should own the personal information display body 10. However, the second display element 42 and the third display element 43 are formed without using a diffractive optical variable element. In other words, the second display element 42 and the third display element 43 are different from the first display element 41 in at least one of the material used and the forming method.

  As described above, since the personal information display body 10 includes a plurality of display elements that are different in at least one of the material and the formation method, the forgery prevention property of the personal information display body 10 can be effectively enhanced. In addition, in the example shown in FIG. 1, the first display element 41 and the second display element 42 which are different in at least one of the material and the forming method both display the same personal information. In particular, the displayed personal information is an image of a person that facilitates authentication, and the first display element 41 as one display element exhibits excellent anti-counterfeiting properties as described above. In such a personal information display 10, first, based on a clear image displayed by the second display element 42, authentication of the owner of the personal information display 10 and authentication of the personal information display 10 are performed. The determination can be made more easily and accurately. In addition, by comparing the personal information displayed by the first display element 41 with the personal information displayed by the second display element 42, the authenticity determination of the personal information display body 10 can be performed more accurately. As a result, the personal information display body 10 has better anti-counterfeiting properties.

  In addition, the 2nd display element 42 and the 3rd display element 43 can be produced by various known methods. As an example, the second display element 42 and the third display element 43 are formed on the display body 20 by transferring the color material to the first oversheet layer 28 of the display body 20 by sublimation heat transfer printing. Can do. The color material thermally transferred to the display body 20 can include various colors corresponding to the second display element 42 and the third display element 43 to be manufactured. In the personal information display 10 for displaying 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 used. Will be thermally transferred. As a result, the diffractive optical variable element 50 and one or more of yellow, magenta, and cyan color materials, or one or more of red, green, and blue materials are formed between the display body 20 and the cover layer 34. A color layer 36 and a black layer 37 made of black are formed.

  In the personal information display 10 shown in FIGS. 5 and 6, the second display element 42 and the third display element 43 are formed from a color layer 36 and a black layer 37 provided on the display body 20 by thermal transfer printing. ing. In the personal information display body 10 shown in FIG. 5, the first oversheet layer 28 of the display body 20 to which the color material is transferred includes a body layer 28a made of, for example, polyethylene terephthalate (PET) or polycarbonate (PC). A receiving layer 28b laminated on the main body layer 28a. In the example shown in FIG. 5, the color layer 36 is formed in the receiving layer 28b, and the black layer 37 and the diffractive optical variable element 50 are formed on the surface of the receiving layer 28b. On the other hand, in the personal information display body 10 shown in FIG. 6, the first oversheet layer 28 to which the color material is transferred is a single material that can receive a dye that forms a color color material such as polyvinyl chloride (PVC). It is formed as a layer. Therefore, in the personal information display body 10 shown in FIG. 6, the color layer 36 is formed in the surface layer of the first oversheet layer 28, and the black layer 37 and the diffractive optical variable element are formed on the surface of the first oversheet layer 28. 50 is formed.

  As another example, at least one of the second display element 42 and the third display element 43 can be formed by a laser engraving method. Further, the second display element 42 and the third display element 43 may be formed by different methods. In the example shown in FIG. 7, the first oversheet layer 28 includes a main body layer 28 a that functions as a support material, and a laser coloring layer 28 c and a receiving layer 28 b that are sequentially stacked on the main body layer 28 a. Yes. A color material can be transferred to the receiving layer 28b by thermal transfer printing. Then, a black layer 37 along the scanning path of the laser light can be formed on the laser coloring layer 28c by irradiating the laser coloring layer 28c with a laser beam in a wavelength range in which the laser coloring layer 28c exhibits sensitivity. As yet another example, the first background print layer 25 of the display body 20 is formed as a laser coloring layer, and personal information is recorded on the first background print layer 25 of the display body 20 by a laser engraving method. You may make it do.

  By the way, although the personal information display body 10 has been described based on the example shown in FIG. 1, the personal information display body 10 shown in FIG. 1 is merely an example. For example, the second display element 42 and the third display element 43 may display personal information different from the example described above. Further, instead of the first to third display elements 41, 42, 43 or in addition to the first to third display elements 41, 42, 43, other display elements are provided in the personal information display body 10. May be.

  Here, another example of the personal information display 10 will be described with reference to FIGS. The personal information display 10 shown in FIGS. 2 and 3 has first to fourth display elements 41, 45, 43, 44. Among these, the first display element 41 and the third display element 43 of the personal information display body 10 shown in FIGS. 2 and 3 are respectively the first display element 41 of the personal information display body 10 shown in FIG. The third display element 43 is the same as the third display element 43. The fourth display element 44 of the personal information display body 10 shown in FIGS. 2 and 3 is the same as the second display element 42 of the personal information display body 10 shown in FIG. Each part of the personal information display 10 shown in FIGS. 2 and 3 is the same as the corresponding part of the personal information display 10 shown in FIG. 1 except for the second display element 45 described in detail below. It can be configured identically.

  In the personal information display 10 shown in FIGS. 2 and 3, the second display element 45 displays the personal information of a specific person who should own the personal information display 10, as with the first display element 41. More specifically, like the first display element 41, the second display element 45 displays the upper body including the face of a specific person who should own the personal information display body 10. In particular, in the example shown in FIGS. 2 and 3, the image displayed by the second display element 45 displays the same image as the image displayed by the first display element 41 with the same size. Further, the image displayed by the first display element 41 and the image displayed by the second display element 45 are overlapped at the same position along the surface direction of the personal information display surface of the personal information display body 10. Is arranged.

  Since the first display element 41 and the second display element 45 manufactured by different methods are arranged at least partially overlapping, it is possible to effectively make forgery of the personal information display body 10 difficult. In particular, in the personal information display 10 shown in FIGS. 2 and 3, the first display element 41 exhibits excellent anti-counterfeiting properties alone as described above, and the first display element 41 has The image and the image of the second display element 45 are overlapped and observed. For this reason, forgery of the personal information display body 10 can be made extremely difficult. Further, since the first display element 41 and the second display element 45 can display the same personal information at the same position, the personal information displayed by the first display element 41 and the second display element 45 are displayed. Therefore, it is possible to more accurately determine the authenticity of the personal information display body by comparing with the personal information.

  In order to expect such an effect, it is preferable that at least one of the first display element 41 and the second display element 45 is formed to be transparent or translucent. For example, the first display element 41 is arranged on the surface side of the personal information display body 10, that is, the observer side, and is formed to be transparent or translucent as already described, and the second display element 45 is the first display element. You may make it arrange | position to the back side of 41, ie, the inner side of the personal information display body 10. FIG. In this case, it is possible to observe the image displayed by the second display element 45 through the transparent or translucent first display element 41, and the effects described here can be obtained.

  In addition, in the personal information display 10 shown in FIGS. 2 and 3, the second display element 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 the second display element 45 can be observed under special conditions. Under normal conditions, the second display element 45 allows the personal information to be displayed. It is possible to prevent the displayed personal information from being visually recognized.

  As an example, the second display element 42 may be manufactured using a fluorescent light emitting material that emits visible light when irradiated with invisible light such as infrared rays or ultraviolet rays. 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. . Further, since the image displayed by the first display element 41 can be more accurately observed under normal conditions, the owner can be authenticated and the personal information display body can be more accurately determined. On the other hand, in a special environment where the fluorescent light emitting material is irradiated only with invisible light having sensitivity, only the personal information displayed by the second display element 45 is observed as shown in FIG. . Thereby, it is possible to easily and accurately carry out the authentication of the owner and the authenticity determination of the personal information display body 10 based on the personal information image displayed by the second display element 45.

  The second display element 45 can be manufactured by various known methods. As an example, the second display element 45 can be provided on the surface layer of the display body 20 or on the display body 20 by thermally transferring the fluorescent light emitting material to the first oversheet layer 28 by a thermal transfer printing method. Further, at least one or more of the display elements 41 to 43 of the personal information display body 10 shown in FIG. 1 and the display elements 41, 43, and 44 of the personal information display body 10 shown in FIGS. The fluorescent light emitting material described here may be used to form the fluorescent color forming layer 38 shown in FIGS.

  Next, an example of a method for manufacturing the personal information display 10 described so far will be described. In the manufacturing method described here, the first display element 41 is transferred to the display body 20 by transferring the diffractive optical variable element 50 to the display body 20 in a desired arrangement pattern by the step of preparing the display body 20 and thermal transfer printing. A step of providing the main body 20, and a step of providing the second display element 42 and the third display element 43 on the display body 20.

  First, the display body 20 can be manufactured by a known method. Specifically, a laminate is produced by laminating a plurality of sheet-like materials, each of which forms the core layers 22 and 23, the background printing layers 25 and 26, and the oversheet layers 28 and 29 described above. To do. Then, the display body 20 is obtained by cutting the obtained laminated body into a desired size. In addition, it is preferable from a viewpoint of production efficiency that the laminated body, which is an intermediate when the display body 20 is manufactured, is formed in such a size that a plurality of display bodies 20 having a desired size can be taken out.

  Next, the process of providing the first to third display elements 41, 42, 43 on the display body 20 will be described mainly with reference to FIGS.

  In the manufacturing method shown in FIGS. 11 to 13, the second display element 42 and the third display element 43 are provided on the display body 20 by transferring the color material to the display body 20 by thermal transfer printing. Similarly, the first display element 41 is provided in the display body 20 by transferring the diffractive optical variable element 50 to the display body 20 in a desired arrangement pattern by thermal transfer printing. For this reason, as shown in FIG. 11, the personal information display manufacturing apparatus 60 includes a thermal transfer apparatus 61 having a thermal head 62.

  As the thermal transfer device 61, a conventionally known thermal transfer printer can be used. In the illustrated example, the thermal transfer device 61 includes a support unit 63 that supports the display body 20 as a transfer target, and a thermal head 62 that heats and presses the thermal transfer sheet 80 toward the display body 20 on the support 63. And a thermal transfer sheet supply means 64 for supplying the thermal transfer sheet 80. The thermal transfer sheet supply means 64 has a feed roll 64a for feeding out the thermal transfer sheet 80 and a recovery roll 64b for collecting the thermal transfer sheet 80 after the thermal transfer. The thermal transfer sheet 80 fed from the feed roll 64a passes between the thermal head 62 and the support means 63 and is collected by the collection roll 64b. In the illustrated example, the display body 20 is supplied one by one from a display body supply means (not shown). The support means 63 is formed as a support table that supports a single card-like display body 20.

  FIG. 12 shows an example of the thermal transfer sheet 80 supplied from the thermal transfer sheet supply means 64. The illustrated thermal transfer sheet 80 includes a long base sheet 89 and a color material region including a color material for forming the second display element 42 and the third display element 43 provided on the base sheet 89. 81, 82, 83, 84, a DOVID region 85 for forming the first display element 41, and a cover layer region 86 for forming the cover layer 34. In the illustrated example, as a color material region including a color material, a yellow region 81 including a yellow dye as a color material, a magenta region 82 including a magenta dye as a color material, and a cyan dye are used. A cyan region 83 including a color material and a black region 84 including a black color material are provided. As shown in FIGS. 12 and 13, a yellow region 81, a magenta region 82, a cyan region 83, a black region 84, a DOVID region 85, and a cover layer region 86 are repeatedly arranged on the base sheet 89. . However, the color material region included in the thermal transfer sheet 80 can be changed as appropriate in accordance with the display elements of the personal information display body 10 to be manufactured.

  By the way, as shown in FIG. 13, in the DOVID region 85 of the illustrated thermal transfer sheet 80, the release layer 85a, the concavo-convex formation layer 85b, the reflection layer 85c, and the heat seal layer 85d are sequentially formed from the base sheet 89 side. It is overlaid on the material sheet 89. In this thermal transfer sheet 80, the thermal head 62 contacts the base sheet 89 and presses the heat seal layer 85 d against the display body 20. Then, the heat seal layer 85d forms the bonding layer 56 of the personal information display body 10 shown in FIG. The reflective layer 85c of the thermal transfer sheet 80 forms the reflective layer 54 of the personal information display body 10 shown in FIG. 10, and the concave / convex forming layer 85b of the thermal transfer sheet 80 becomes the personal information display shown in FIG. The unevenness forming layer 52 of the body 10 is formed. That is, in the illustrated thermal transfer sheet 80, the reflective layer 85 c and the unevenness forming layer 85 b form the diffractive optical variable element 50 that forms the first display element 41. Moreover, the peeling layer 85a is a layer which has peelability with respect to the adjacent uneven | corrugated formation layer 85b.

  As described above, the diffractive optical variable element 50 can be formed from various elements whose manner of observation, for example, brightness, color, etc., changes depending on the observation direction by using the diffraction phenomenon. For this reason, the configuration of the DOVID region 85 of the thermal transfer sheet 80, in particular, the concave / convex forming layer 85b and the reflective layer 85c of the DOVID region 85 are appropriately changed according to the configuration of the diffractive optical variable element 50 to be transferred onto the display body 20 can do. For example, the DOVID region 85 of the thermal transfer sheet 80 may include a transmission type hologram or diffraction grating, or may include a volume type hologram or diffraction grating.

  As shown in FIG. 13, in the illustrated cover layer region 86 of the thermal transfer sheet 80, a release layer 86a, a protective layer 86b, an ultraviolet absorbing layer 86c, and a heat seal layer 86d are sequentially formed from the base sheet 89 side. It is overlaid on the base material sheet 89. The cover layer region 86 comes into contact with the display body 20 from the heat seal layer 86 d side when the thermal head 62 contacts the base sheet 89. When the cover layer 34 of the personal information display body 10 shown in FIG. 10 is formed using the thermal transfer sheet 80, the cover layer 34 includes a heat seal layer 86d, an ultraviolet absorbing layer 86c, and a protective layer 86b. The protective layer 86b is a layer that forms the outermost surface of the personal information display body 10, and preferably has transparency, scratch resistance, and the like. The ultraviolet absorbing layer 86c is a layer located inside the protective layer 86b, that is, on the diffractive optical variable element 50 side in the personal information display body 10, and absorbs ultraviolet rays. Thereby, it can prevent effectively that the display elements 41, 42, and 43 of the personal information display body 10 located inside the ultraviolet absorption layer 86c are deteriorated by ultraviolet rays.

  Using the thermal transfer device 61 and the thermal transfer sheet 80 of the manufacturing apparatus 60 as described above, the display elements 41, 42, 43 and the cover layer 34 are formed on the display body 20 as follows.

  First, the display body 20 to be processed next is supplied onto the support means 63. The thermal transfer sheet 80 is supplied between the thermal head 62 and the support means 63 by the thermal transfer sheet supply means 64 in accordance with the supply of the display body 20. The thermal transfer sheet 80 is positioned so that the yellow area 81 faces the display body 20 on the support means 63. In this state, the thermal head 62 sublimates and transfers the yellow dye in the yellow region 81 onto the display body 20 in a predetermined arrangement pattern. Next, in a state where the display body 20 is held on the support means 63, the thermal transfer sheet 80 is conveyed, and the magenta area 82 located next to the yellow area 81 where the thermal transfer process is completed faces the display body 20. become. In this state, the thermal head 62 sublimates and transfers the magenta dye in the magenta region 82 onto the display body 20 in a predetermined arrangement pattern. By the same processing, the cyan dye and the black color material in the cyan region 83 are sublimated and thermally transferred onto the display body 20 in a desired pattern. As described above, the color layer 36 and the black layer 37 are formed on the display body 20.

  Thereafter, the thermal transfer sheet 80 is conveyed so that the DOVID area 85 of the thermal transfer sheet 80 faces the display body 20 on the support means 63. In this state, the thermal head 62 is arranged so that the DOVID region 85 of the thermal transfer sheet 80 contacts the predetermined unit region 48 among the plurality of unit regions 48 virtually defined on the display body 20. Is pushed in while heating the corresponding position of the thermal transfer sheet 80. Due to the heating from the thermal head 62, the heat seal layer 85d in the DOVID region 85 has adhesiveness at a position where the heat seal layer 85d contacts the display body 20. For this reason, the unevenness forming layer 85b is peeled off from the release layer 85a having releasability, and the reflective layer 85c and the unevenness forming layer 85b are removed from the base sheet 89 of the thermal transfer sheet 80 via the heat seal layer 85d. Transcribed above. In this way, the diffractive optical variable element 50 including the reflective layer 85c and the unevenness forming layer 85b is thermally transferred onto the display body 20. Finally, the diffractive optical variable element 50 is provided on the display body 20 in an arrangement pattern capable of displaying the personal information of the specific person to whom the personal information display body 10 is to be provided. As described above, the first display element 41 including the diffractive optical variable element 50 is formed on the display body 20.

  Next, the thermal transfer sheet 80 is conveyed, and the cover layer region 86 of the thermal transfer sheet 80 faces the display body 20 on the support means 63. The cover layer region 86 is transferred to the entire area on the display body 20 by heat and pressure from the thermal head 62. Therefore, the first display element 41, the second display element 42, and the third display element 43 provided in the display body 20 are a cover that includes the ultraviolet absorbing layer 86c and the protective layer 86b joined via the heat seal layer 86d. It becomes covered by the layer 34. The ultraviolet absorbing layer 86c can be omitted as necessary.

  As described above, the personal information display 10 shown in FIG. 1 can be manufactured. According to the above manufacturing method, the personal information display body 10 having extremely excellent anti-counterfeiting properties and capable of performing owner authentication and authenticity determination extremely easily and accurately is manufactured relatively easily without difficulty. can do. Further, according to this method, one thermal transfer sheet 80 is a region for forming the first display element 41, the second display element 42, the third display element 43, and the cover layer 34 of one personal information display body 10. Contains all. Therefore, the first display element 41, the second display element 42, and the third display element 43 can be accurately positioned with respect to each other.

  However, the above manufacturing method is merely an example, and various modifications can be made. For example, in the manufacturing method described above, an example in which the first display element 41, the second display element 42, the third display element 43, and the cover layer 34 are formed on the display body 20 by thermal transfer has been described. It is not limited to this. The first display element 41, the second display element 42, and the third display element 43 are formed on the cover layer 34 by thermal transfer, and then the first display element 41, the second display element 42, and the third display element 43 are formed. The personal information display body 10 may be manufactured by laminating the cover layer 34 formed with the above structure on the display body main body 20.

  Although not particularly mentioned in the above manufacturing method, the receiving layer 28b that can receive the dye may be thermally transferred onto the display body 20 prior to the sublimation thermal transfer of the coloring material containing the dye. In this case, the thermal transfer sheet 80 may have an area including the receiving layer between the cover layer area 86 and the yellow area 81.

  Furthermore, each region included in the thermal transfer sheet 80 can be appropriately changed according to the configuration of the display element to be formed on the display body 20. As an example, in the personal information display body 10 shown in FIGS. 2 and 3, the second display element 45 using a fluorescent material is provided on the display body 20. Therefore, as shown in FIG. 14, if the thermal transfer sheet 80 further includes a fluorescent light emitting material region 88 containing a fluorescent light emitting material, the second information of the personal information display body 10 shown in FIG. 2 and FIG. The display element 45 can be formed on the display body 20 by thermal transfer. In the thermal transfer sheet 80 shown in FIG. 14, the DOVID region 85 for forming the first display element 41 and the fluorescent light emitting material region 88 for forming the second display element 45 are the same base sheet 89. Since they are arranged side by side, the first display element 41 and the second display element 45 can be aligned with respect to each other with high accuracy. Thereby, the personal information display body 10 including the first display element 41 and the second display element 45 that display the same image at the same position can be manufactured relatively easily without difficulty.

  Further, a thermal transfer sheet for forming the color layer 36 on the display body 20 and a thermal transfer sheet for forming the diffractive optical variable element 50 and the cover layer 34 on the display body 20 are prepared separately. Anyway. FIG. 16 shows a first thermal transfer sheet 80a in which a yellow region 81, a magenta region 82, a cyan region 83, and a black region 84 are repeatedly formed in order on a base sheet 89. Such a first thermal transfer sheet 80a is widely used in normal sublimation thermal transfer printing without being limited to application to the personal information display 10, and is available at low cost. On the other hand, FIG. 17 shows a second thermal transfer sheet 80 b in which a DOVID area 85 and a cover layer area 86 are repeatedly formed in order on the base sheet 89.

  FIG. 15 shows a method of manufacturing the personal information display 10 using the first thermal transfer sheet 80a shown in FIG. 16 and the second thermal transfer sheet 80b shown in FIG. In the manufacturing method shown in FIG. 15, the personal information display manufacturing apparatus 60 is arranged downstream of the thermal transfer apparatus 61 along the transport direction of the display body 20 in addition to the thermal transfer apparatus 61 described above. A second thermal transfer device 66 is further provided. Similar to the thermal transfer device 61, the second thermal transfer device 66 can be configured by a known thermal transfer printer. The thermal transfer sheet supply means 64 of the thermal transfer device 61 supplies the first thermal transfer sheet 80a. Therefore, the thermal transfer device 61 forms the color layer 36 and the black layer 37 on the display body 20.

  On the other hand, the second thermal transfer device 66 includes a second thermal transfer sheet supply unit 69 that supplies the second thermal transfer sheet 80b, and a second support unit 68 that supports the display body 20 on which the color layer 36 and the black layer 37 are formed. And a second thermal head 67 that heats and presses the second thermal transfer sheet 80b toward the display body 20 on the second support means 68. The second thermal transfer sheet supply means 69 has a feed roll 69a for feeding out the second thermal transfer sheet 80b and a recovery roll 69b for collecting the second thermal transfer sheet 80b after the thermal transfer. The second thermal transfer sheet 80b fed from the feed roll 69a passes between the second thermal head 67 and the second support means 68 and is collected by the collection roll 69b.

  In the illustrated example, the display body 20 is supplied to the first thermal transfer device 61 one by one from a display body supply means (not shown). Then, in the first thermal transfer device 61, the color layer 36 and the black layer 37 are thermally transferred to the display body 20. The display body 20 on which the color layer 36 and the black layer 37 are formed is then transported to the second thermal transfer device 66, where the diffractive optical variable element 50 and the cover layer 34 are placed on the display body 20. Thermally transferred.

  Further, in the personal information display 10 shown in FIGS. 1 to 3, the area where the diffractive optical variable element 50 is transferred on the display body 20 is small. Therefore, as shown in FIG. 18 as an example, even if the size of the DOVID region 85 in the thermal transfer sheet 80 and the second thermal transfer sheet 80b is reduced in consideration of the size of the diffractive optical variable element 50 to be transferred. Good. In this case, the cost of the thermal transfer sheet 80 and the second thermal transfer sheet 80b can be effectively reduced. In connection with this, the manufacturing cost of the personal information display body 10 can be reduced effectively.

Display personal information. Thus, since the 1st display element 41 is formed using the diffractive optical variable element 50, forgery of the personal information display body 10 can be made difficult. On the other hand, personal information only needs to be displayed in the arrangement pattern of the diffractive optical variable element 50, so that there is no need to record the personal information on the diffractive optical variable element 50 itself, for example, as an uneven structure or interference fringes. Therefore, according to the personal information display 10 of the present embodiment, it can be manufactured relatively easily and can exhibit excellent anti-counterfeiting properties.

  In particular, according to the present embodiment, the first display element 41 displays an image of a specific person by the arrangement pattern of the diffractive optical variable element 50. In general, in order to authenticate the owner of the personal information display body 10 based on the personal information display body 10, it is preferable that an image of the owner, particularly a face, is displayed on the personal information display body 10. When the image of the owner, in particular, the face is recorded on the personal information display body 10, the authentication of the owner and the authentication of the personal information display body 10 based on the authentication result can be easily and accurately performed. it can. And according to this Embodiment, the 1st display element 41 displays an owner's image, especially a face, with the arrangement pattern of the diffractive optical variable element 50 which requires advanced manufacturing technology.
