Description

  The present invention relates to an image display body that prints, prints, and draws a face image and a fingerprint, which are essential to individual identification, on a booklet such as a passport or a visa or a personal authentication medium such as a card. For personal identification by combining a structure with a diffraction structure and on-demand printing technology for personal identification information such as the face of a unique owner, and also having confidential information with an emission angle different from that of personal identification information It relates to a technology that makes it easy for an officer to identify and counterfeiting and tampering, or makes it easier for an examiner to detect.

  Many personal authentication media such as passports and ID (identification) cards use facial images to enable visual personal authentication. For example, in a passport, conventionally, photographic paper on which a face image is printed is pasted on a booklet. However, such passports may be tampered with by reprinting photographic prints.

  For these reasons, in recent years, face image information has been digitized and reproduced on a booklet. For this image reproduction method, for example, sublimation (heat transferable) dyes, thermal transfer recording methods using transfer ribbons using resin-type melting type or wax-melting type in which pigments are dispersed, or electrophotographic methods are examined. Has been.

  However, recently, thermal transfer recording printers using sublimation dyes or colored thermoplastic resins have become widespread. Considering this situation, it is not always difficult to remove a face image from the passport and record another face image in that portion.

  By the way, a phosphor printed matter having a configuration in which a face image is recorded using the image display technique as described above and the face image is recorded thereon using fluorescent ink has been proposed (see, for example, Patent Document 1). Further, a forgery-preventing image forming body (for example, see Patent Document 2) in which a face image is recorded using an ink containing a colorless or light fluorescent dye and a colored pigment, and further using a normal face image and a pearl pigment. There has been proposed a personal authentication medium in which the formed face images are arranged side by side (for example, see Patent Document 3).

  Therefore, if the image display technique as described above is applied to a passport, the falsification becomes more difficult. However, a face image recorded using a fluorescent material cannot be observed unless a special light source such as an ultraviolet lamp is used. Further, although a face image formed using a pearl pigment is visible with the naked eye, since the particle size of the pearl pigment is large, it is difficult to form a high-definition image using the pearl pigment.

  Further, when the appearance of the face image recorded on the personal authentication medium is simple and has no visual effect, the falsification is compared with the case where the face image has a complicated and characteristic visual effect. Is easy. Further, when the face image is displayed in a simple manner, it is difficult to easily visually determine the falsified and forged face image.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a schematic view showing an example of an image display body manufacturing apparatus 1 according to the present invention. In FIG. 1, 2 is a hologram transfer foil, 3 is a substrate to be transferred, 11 is an image input means, 12 is a control means such as a PC (Personal Computer), 13 is a secret information transfer roll, 14 is a transfer print control means, Reference numeral 15 denotes a thermal head serving as a thermal transfer recording / printing section. The hologram transfer foil 2 has a mechanism for performing thermal pressure printing on the transfer target substrate 3 by the thermal head 15 and the secret information transfer roll 13. The transfer printing control unit 14 controls the thermal head 15 in accordance with an instruction from the control unit 12.

  Further, on the secret information transfer roll 13, a secret information owner 131 and a secret information non-owner 132 are provided. The secret pattern of the secret information possessing unit 131 is formed by irregularities arranged in a geometric pattern or / or irregularities of binary character / graphic patterns arranged periodically. The difference in height between the concaves and convexes is typically 0.2 μm or less, and it is designed so that only the convex part is printed because there is a difference in how heat is transferred between the concave part and the convex part at the time of hot-pressure printing. . Therefore, in the secret information possessing part 131, the secret pattern formed by the convex part is printed on the transfer base material 3 as the secret information recording layer 22 as shown in FIGS. In this case, since there is no unevenness, the individual information recording layer 21 that does not include the secret pattern can be printed on the transferred substrate 3. That is, it is possible to print an information recording layer partially containing confidential information on the substrate 3 to be transferred.

  It is also possible to provide the secret information possessing portion 131 of the secret information transfer roll 13 by the same area as that of one type of relief structure forming portion of the hologram transfer foil 2 to be described later, and to perform printing in conjunction therewith. Specifically, for example, the secret information possessing portion 131 is provided in the same area as the relief structure forming portion H1 of FIG. 3, and the secret information recording layer 22 is formed on the transferred substrate 3 by performing recording printing of a predetermined area. Thereafter, it is possible to perform recording printing through the relief structure forming portion H2 using the secret information non-owning portion 132, and to form the individual information recording layer 21 on the secret information recording layer 22.

  FIG. 2 is a schematic diagram illustrating another example of the image display body manufacturing apparatus according to the present invention. Here, the secret information transfer roll 13a having a secret pattern on the entire roll and the transfer roll 13b having no secret pattern are illustrated. Two hot-pressure printing mechanisms are provided.

  The secret information recording layer 22 and the individual information recording layer 21 (see FIG. 4 to FIG. 6) are subjected to hot-pressure printing partially or entirely on the entire print designation area in the secret information recording unit 13A and the individual information recording unit 13B, respectively. . In FIG. 2, the secret information recording layer 22 is formed by the secret information recording unit 13A, and then the individual information recording layer 21 is formed by the individual information recording unit 13B. The order of the individual information recording unit 13B may be reversed. That is, after the individual information recording layer 21 is formed by the individual information recording unit 13B, the secret information recording layer 22 may be formed by the secret information recording unit 13A.

  FIG. 3 is a cross-sectional view schematically showing an example of the hologram transfer foil 2 used in the image display body manufacturing apparatus 1 in FIGS. 1 and 2. The hologram transfer foil 2 is formed by sequentially laminating a release layer, a diffraction structure forming layer, and an adhesive layer on one surface of a substrate.

  The base material of the hologram transfer foil 2 is, for example, a resin film or sheet, for example, a plastic such as polyethylene terephthalate (PET), polypropylene (PP), polycarbonate (PC), polymethyl methacrylate (PMMA), polyethylene (PE), etc. Made of material.

  The release layer of the hologram transfer foil 2 serves to stabilize the release of the hologram transfer foil 2 from the base material and promote adhesion to the transfer base material 3. The release layer has optical transparency and is typically transparent. Examples of the release layer material include polycarbonate resin, acrylic resin, fluorine acrylic resin, silicone acrylic resin, epoxy acrylate resin, polystyrene resin, cycloolefin polymer, methylstyrene resin, fluorene resin, PET, polypropylene, and polyethylene. Examples include thermoplastic resins such as terephthalate resin and polyacetal resin to which silicone or fluorine-based additives are added, fluorine-based acrylic resins, silicone-based acrylic resins, and the like.

  Examples of the material for the diffraction structure forming layer formed on the release layer of the hologram transfer foil 2 include polycarbonate resin, acrylic resin, fluorine-based acrylic resin, silicone-based acrylic resin, epoxy acrylate resin, polystyrene resin, and cycloolefin. Polymer, methyl styrene resin, fluorene resin, PET, polypropylene or other photo-curable resin, or acrylonitrile styrene copolymer resin, phenol resin, melamine resin, urea resin, alkyd resin, or other thermosetting resin, or polypropylene resin, Examples thereof include thermoplastic resins such as polyethylene terephthalate resin and polyacetal resin, and a diffractive structure forming layer can be formed on the surface of the release layer by molding and curing the above resin into a desired structure. .

  In addition, all the hardened | cured materials of resin which form the diffraction structure formation layer of the hologram transfer foil 2 are light transmittances, and a refractive index is generally about 1.5. The total thickness of the release layer, the diffractive structure forming layer, and the adhesive layer is preferably thin in order to improve heat resistance, foil breakability, and thermal transfer property, and is preferably 1.5 μm or less.

The diffractive structure forming layer includes hologram and / or diffraction grating relief structure forming portions H1 and H2. The parameters of the relief structure forming portions H1 and H2 are as follows:
(1) Spatial frequency of relief structure (pitch of grid lines: number of grid lines per unit length)
(2) Relief structure direction (lattice line direction)
According to (1) above, the color in which the image cell appears to shine changes, and in accordance with (2) above, the direction in which the image cell appears to shine changes.

  The relief structure forming portions H1 and H2 may or may not have the same parameters (1) and (2), but preferably at least one of the parameters (1) and (2). The above is different.

  The relief structure forming layer may include a reflective layer. When the reflective layer is provided, the visibility of the image displayed by the diffraction structure forming layer is improved. As the reflective layer, for example, a transparent reflective layer can be used. The transparent reflective layer can be formed by, for example, a vacuum film forming method such as vacuum deposition or sputtering.

  As the transparent reflection layer, for example, a layer made of a transparent material having a refractive index different from that of the diffraction structure forming layer can be used. The transparent reflective layer made of a transparent material may have either a single layer structure or a multilayer structure. In the latter case, the transparent reflective layer may be designed so as to repeatedly cause reflection interference. As this transparent material, for example, a transparent dielectric such as zinc sulfide and titanium dioxide can be used.

Further, a metal layer having a thickness of less than 20 nm may be used as the transparent reflective layer. As a material for the metal layer, for example, a single metal such as chromium, nickel, aluminum, iron, titanium, silver, gold, and copper, or an alloy thereof can be used.
The thickness of the transparent reflective layer is typically preferably about 50 nm to 100 nm.

  Examples of the material of the adhesive layer formed on the diffractive structure forming layer include thermoplastic resins such as polypropylene resin, polyethylene terephthalate resin, polyacetal resin, and polyester resin. These resins include inorganic materials such as silica. Fine particles may be added.

Next, the formation method of the image display body 4 containing confidential information and individual information is demonstrated using FIG. 4, FIG.
4 and 5, the hologram transfer foil 2 is placed on the surface of the substrate 3 to be transferred so that the base of the hologram transfer foil 2 is on the upper side, and the hologram transfer foil 2 is heated on the upper surface of the hologram transfer foil 2. Obtained by applying pressure. Specifically, since only the hologram transfer foil 2 to which the heat pressure is applied is transferred onto the surface of the substrate 3 to be transferred, the hologram transfer foil 2 is transferred to a required position on the surface of the substrate 3 to be transferred. An image display body 4 can be obtained.

  The substrate 3 to which the hologram transfer foil 2 is transferred includes a substrate and an image receiving layer. As said base material, what was illustrated about the base material of the hologram transfer foil 2, for example can be used. Further, the image receiving layer is made of a material that has good adhesion to the adhesive layer of the hologram transfer foil 2.

  In forming the secret information recording layer 22 of the image display body 4, for example, the relief structure forming portion H <b> 1 is applied to the transfer substrate 3 using the thermal head 15 and the secret information transfer rolls 13 and 13 a of FIGS. 1 and 2. Print with hot pressure. At this time, the secret information transfer rolls 13 and 13a have a concavity and convexity of the concealment pattern, and the manner of heat transfer differs between the concave portion and the convex portion. Therefore, the hologram transfer foil 2 is transferred onto the substrate 3 to be transferred along the secret pattern formed by the convex portion of the secret information possessing part 131, thereby the secret information recording layer 22 containing the secret information. Is formed.

  The thermal transfer area of the secret information recording layer 22 is at least 10% of the transfer designated area. The transfer shape is preferably a continuous shape so that confidential information can be confirmed.

  Next, the formation of the individual information recording layer 21 for authenticating the individual of the image display body 4 will be described. As information for authenticating an individual, for example, image information is obtained as electronic information by photographing a person's face or reading a face image from a print using an imaging device. Then, the thermal head 15 shown in FIG. 1 and the secret information non-owning portion 132 of the secret information transfer roll 13 shown in FIG. 1 or the transfer roll 13b shown in FIG. The information recording layer 21 is formed. At this time, since there is no unevenness on the transfer roll, this thermal transfer uses the thermal head 15 and the portion that is thermally transferred from the hologram transfer foil 2 to the transfer substrate 3 corresponds to the previous face image. It can be done to have a pattern.

  Since the pattern corresponding to the face image obtained in this way is formed by thermal transfer using the thermal head 15, it typically comprises a plurality of dot shapes or line shapes.

  The diameter of the dot-shaped portion or the line width of the linear portion is, for example, in the range of 0.085 to 0.508 mm (about 300 to about 50 dots per inch), and typically 0.085 to 0.169 mm. (About 300 to about 150 dots per inch). When this dimension is increased, it is difficult to display a high-definition image when displaying a face image. Further, when this dimension is reduced, the reproducibility of the diameter of the dot-shaped part or the line width of the linear part is lowered.

  The individual information recording layer 21 formed here is not limited to a single color. For example, relief structure forming portions having different spatial frequencies are provided on the hologram transfer foil 2 so that the color appearance at a fixed point becomes three colors of R, G, and B, and the full color is obtained by sequentially superimposing / transferring them side by side. An individual information image can be obtained. This facilitates identification of the person.

  Moreover, the information of the individual information recording layer 21 formed here is not necessarily binary. By dividing the original image into two or more levels of gradation and performing gradation printing corresponding to the previous face image, it becomes possible to identify the person more easily and surely, and prevent forgery and tampering It becomes the provided image display.

In the image display body 4, the confidential information recording layer 22 and the individual information recording layer 21 may be on the same plane as shown in FIG. 4, or may overlap as shown in FIG.
When the secret information recording layer 22 and the individual information recording layer 21 are on the same plane as shown in FIG. 4, the secret information recording layer 22 and the individual information recording layer 21 are the same relief structure forming portion H1 of the hologram transfer foil 2. It may be printed, or may be printed with different relief structure forming portions (here, H1 and H2).

  When the confidential information recording layer 22 and the individual information recording layer 21 are overlapped as shown in FIG. 5, the confidential information recording layer 22 and the individual information recording layer 21 need to be printed by different relief structure forming units. Even if the individual information recording layer 21 is formed after the information recording layer 22 is formed, the individual information recording layer 21 may be formed first, and the secret information recording layer 22 may be formed later.

  FIG. 6 is a diagram showing an observation state of the image display body 4 in which the secret information recording layer 22 and the individual information recording layer 21 are both printed on the same surface by the relief structure forming unit H1. When the image display body 4 produced as described above is observed from the observation range 40a shown in FIG. 6, the individual information 41 for authenticating the individual shown in FIG. 7 and the confidential information 42 can be observed.

  FIG. 8 is a diagram showing an observation state of the image display body 4 in which the secret information recording layer 22 and the individual information recording layer 21 are printed on the same surface by the relief structure forming portions H1 and H2, respectively. The relief structure forming portions H1 and H2 have different spatial frequencies, different lattice angles, or different both spatial frequencies and lattice angles.

  When the image display body 4 manufactured as described above is observed from the observation range 40a shown in FIG. 8, the individual information 41 for authenticating the individual shown in FIG. 9A can be observed. Further, when observing from the observation range 40b, the diffracted light of the individual information 41 cannot be observed, and instead, the confidential information 42 shown in FIG. 9B can be observed.

  FIG. 10 is a diagram showing an observation state of the image display body 4 in which the secret information recording layer 22 and the individual information recording layer 21 are printed using the relief structure forming portions H1 and H2, respectively. The relief structure forming portions H1 and H2 have different spatial frequencies, different lattice angles, or different both spatial frequencies and lattice angles.

  When the image display body 4 produced as described above is observed from the observation range 40a shown in FIG. 10, the individual information 41 for authenticating the individual shown in FIG. 11A can be observed. Further, when observing from the observation range 40b, the diffracted light of the individual information 41 cannot be observed, and instead, the confidential information 42 shown in FIG. 11B can be observed.

FIG. 12 is a plan view schematically showing an example of the personal authentication medium 5 produced by transferring the image display body 4 produced as described above.
The personal authentication medium 5 shown in FIG. 12 is obtained by thermal transfer of the image display body 4 shown in FIG. For this thermal transfer, for example, a hot stamp is used. Instead of thermal transfer using a hot stamp, thermal transfer using a hot roll or a thermal head may be performed. The personal authentication medium 5 is obtained as described above.

When the image display body 4 is thermally transferred to the personal authentication medium 5, an adhesive anchor layer may be formed on the base material of the personal authentication medium 5 in order to increase the adhesive strength.
When it is difficult to adhere to the base material of the personal authentication medium 5 with high adhesive strength, thermal transfer may be performed via an adhesive layer. For example, an adhesive ribbon may be used.

  The material of the base material to which the image display body 4 is attached may be other than paper. For example, the base material to which the image display body 4 is attached may be a plastic base material, a metal substrate, a ceramic substrate, or a glass substrate.
