  Hereinafter, various materials, manufacturing methods, and the like constituting the magnetic card (100) or the IC card (200) to which the forgery prevention measure of the present invention is applied will be specifically described.

First, as the transparent center core (10), a plastic sheet having a thickness of about 0.6 mm is used. For example, a vinyl chloride resin that has been conventionally used, an environment-friendly alternative to this vinyl chloride resin, and embossing suitability, etc. Excellent ethylene-1,4-cyclohexylene dimethylene terephthalate (amorphous thermoplastic polyester) resin (commonly known as PETG)
In addition, polyethylene terephthalate resin (PET), acrylonitrile-butadiene-styrene copolymer (ABS) and the like can also be used.

  As the oversheet (11) to be laminated on both the front and back sides of the transparent center core (10), for example, a vinyl chloride resin film of about 0.1 mm is generally used, but environmentally friendly vinyl chloride-vinyl acetate is used. A polymer or the like can also be used.

  Further, the silver concealment layer (15) applied to the portion excluding the transparent region (L) and the IC chip / antenna portion (13) is, for example, the presence or absence of a card or magnetic information by a machine such as ATM (Automated Teller's Machne). It is necessary to provide at least both sides of the card, and further serves to elevate the design layer (17) provided by printing or the like on the card, For example, the transparent region (L) and the IC chip / antenna portion (13) were removed by screen printing or flexographic printing using anilox roll using an ink in which white pigment (titanium oxide or the like) was dispersed in aluminum paste. The part can be provided with a part coat.

  The overcoat layer (17) serves to protect the card from mechanical friction or the like, and is composed of a film mainly composed of a resin having excellent heat resistance and fastness such as acrylic and polyester resins. A resin in which 1 to 5% by weight of a silicon-based or ethylene-based wax is mixed with these resins is used.

  A fluorescent pigment used as the fluorescent pattern (14) according to claim 1 or the convex fluorescent character / number (18) according to claim 2 constituting an ID card to which the forgery prevention measure of the present invention is applied. There are organic fluorescent pigments and inorganic fluorescent pigments. The former organic fluorescent pigments consist of a fluorescent dye and a synthetic resin solid solution. For example, the fluorescent dye is yellow in daylight and green to yellow in blacklight. Examples include green brilliant sulfoflavin FF, thioflavine, basic yellow, or fluorescein. Synthetic resins that serve as carriers for these fluorescent dyes include polymethacrylate, urea, formalin resin, melamine / formalin resin, vinyl chloride, Examples thereof include a vinyl chloride-vinyl acetate copolymer, an alkyd resin, and a modified product thereof. Examples of the latter inorganic fluorescent pigment include heat-resistant pigments such as Zn2SiO4 / Mn and CaWO4 that emit light only in the wavelength range of 200 to 300 nm, and are used for forming the fluorescent pattern (14). Printing inks are obtained by dispersing the above organic fluorescent pigments or inorganic fluorescent pigments in a printing ink vehicle (for gravure, for screens, for offsets). (14) can be formed.

  Furthermore, the fluorescent ink used for forming the convex fluorescent letters / numbers (18) is obtained by dispersing the organic fluorescent pigment or the inorganic fluorescent pigment in a photocurable resin system. Specifically, , Urethane-based acrylate monomers, ester-based acrylate monomers, epoxy-based acrylate monomers, and other known photocurable monomers, or urethane-based acrylate prepolymers, ester-based acrylate prepolymers, epoxy-based acrylate prepolymers, and other known photocurable prepolymers. A polymer precursor made of a polymer, in which a known photopolymerization initiator such as acetophenone, 2,2-diethoxyacetophenone, p-dimethylaminoacetophenone, benzophenone, p-chlorobenzophenone, and the like and a fluorescent pigment are dispersed, For 100 parts by mass of the polymer precursor, Be provided with 8 parts by mass be contained is desirable viscosities, etc. of the fluorescent ink.

For example, as shown in the schematic cross-sectional view of FIG. 3, a printer (300) used for Braille printing or the like can be used to form convex fluorescent characters / numbers (18) using the fluorescent ink having the above composition. . The printer (300) includes a printing unit (51) for applying photocurable fluorescent ink to the surface of the IC card (200), which is a substrate, and curing for curing the fluorescent ink applied to the surface of the IC card (200). The printing part (51) is provided with an ink cylinder (21) filled with fluorescent ink and a card holding means (31) for holding an IC card (200) to be printed. The part (52) is provided with a card holding means (32) for holding the light irradiation means (40) and the printed IC card (200).

  Using the printer (300), the fluorescent ink (70) in the ink cylinder (21) is ejected from the nozzle (22) to a predetermined position on the surface of the IC card (200) to obtain a desired convex fluorescent letter / number. Next, the IC card (200) on which the convex fluorescent letters / numbers are formed is conveyed to the curing unit (52), and is irradiated with ultraviolet rays of 365 nm having a relatively low intensity as a photocuring means (40). Irradiation with a lamp cures the convex fluorescent letters / numbers, and the convex fluorescent letters / numbers (18) having a thickness of 0.20 to 0.48 mm can be formed as embossed letters.

  The magnetic card (100) and the IC card (200) on which the anti-counterfeit measures obtained as described above are applied do not notice that the anti-counterfeit measures are applied at first glance. The determination is based on whether or not the fluorescent pattern on the inner surface of the transparent region or convex fluorescent letters / numbers (commonly called embossed letters) emits fluorescence by irradiation with special light, for example, a black lamp (fluorescent lamp) having a peak wavelength of 352 nm. Can be determined.
