The embodiment of the card provided with the easily peelable concealing layer of the present invention is as shown in FIGS. As shown in FIG. 1, the planar shape of one surface is printed with a predetermined number of card numbers 7 at a predetermined position in the center of the card by data output and easily peeled so as to cover the entire card number 7 This is a configuration in which the concealment concealment layer 4 is formed and the card number 7 is concealed. As shown in FIG. 2, the laminated structure is such that a printed layer 2 composed of fixed information and a pattern is formed on one surface of the base material layer 1, and a card having a predetermined number of digits in a predetermined area of the printed layer 2 surface. The number 7 is printed by data output, and the transparent resin layer 3 is formed so as to cover the entire surface of the printed card number 7 and the printed layer 2, and the card number 7 on the upper surface of the transparent resin layer 3 corresponds to the printed region. An easily peelable hiding layer 4 is formed at a position, and a tint block printing layer 5 and a protective layer 6 are sequentially formed on the easily peelable hiding layer 4, and the other surface of the base material layer 1 has a hiding layer 8 and The print layer 9 is provided in order.
[0013]
In the embodiment of the present invention, the card number 7 is printed by data output at 10 to 50% halftone dots. FIG. 3 shows a state in which the card number 7 is printed with a halftone dot of 40%. When the card number 7 is printed by solid printing, even if the easily peelable hiding layer 4 is formed on the surface of the card number 7, the card number 7 is raised, and the card number 7 is placed on the easily peelable hiding layer 4. However, when the card number 7 is printed with 10% to 50% halftone dots, the rise of the printed card number 7 portion is reduced, so the card number printed from the outside. 7 cannot be recognized. Furthermore, by forming the tint block printing layer 5 on the surface of the easily peelable concealing layer 4, the card number 7 due to the rise of the card number 7 portion is more reliably prevented from being recognized from the outside. The protective layer 6 is provided to prevent the easily peelable hiding layer 4 and the tint block printing layer 5 from being rubbed or damaged during handling during transportation and storage.

The easily peelable concealing layer 4 is formed by printing using an opaque ink, but it is necessary that the formed ink film be easily peelable with a nail, a coin, etc. The resins used for the above are natural rubber, polybutadiene, styrene-butadiene copolymer, acrylonitrile-butadiene copolymer, synthetic rubber such as polyisoprene, polychloroprene, chlorinated polyethylene, chlorinated polypropylene, chlorinated rubber, ethylene-acetic acid. Resin such as vinyl copolymer, ABS resin, iron oxide, titanium oxide, cobalt oxide, pearlescent pigment, inorganic pigment such as carbon black, organic pigment such as phthalocyanine blue, metal powder such as copper powder and aluminum powder , A plasticizer, a release agent, and a solvent are used. In order to be able to completely conceal the card number 7 printed by the easily peelable hiding layer 4, it is necessary to print the easily peelable hiding layer 4 as a thick layer, so that a thick ink layer is formed. It is preferable to carry out by silk screen printing.
[0017]
The base material layer 1 is required to be strong and excellent in strength and opaque. Therefore, as the base material layer, a biaxially stretched polyethylene terephthalate film having voids, a biaxially stretched polypropylene film, or the like is suitable. These are white opaque films having voids produced by adding an inorganic fine powder to polyester or polypropylene and extruding into a film shape and stretching in biaxial directions. As the biaxially stretched polyethylene terephthalate film having voids, Crisper (Toyobo) or the like can be used, and as the biaxially stretched polypropylene film having voids, YUPO (Oji Oil) or the like can be used. The thickness of the base material layer 1 is suitably 150 to 250 μm. As the base material layer 1, a laminate of a plastic film, a paperboard, and a plastic film can be used in addition to the above structure. As the plastic film, polyvinyl chloride, polyethylene, polypropylene, polystyrene, polyester and the like are arbitrary, but a film having excellent rigidity and surface strength such as biaxially stretched polyethylene terephthalate film is preferable.
[0018]
The manufacturing method uses, for example, a roll-shaped crisper as the base material layer 1 to provide feed holes on both ends, print the printing layer 2 on one surface, and opaque concealment on the other surface. The masking layer 8 is provided using ink, and the printing layer 9 is formed thereon. Printing is preferably performed by an offset printing method using ultraviolet curable ink or the like. Using a non-impact printer or the like on the surface of the printing layer 2 of the base material layer 1 provided with the printing layer 2 on one side and the concealing layer 8 and the printing layer 9 on the other side, the card number 7 is placed at a predetermined position. Print with 10 to 50% halftone dot by data output. A transparent resin layer 3 made of, for example, a biaxially stretched polyethylene terephthalate film having a thickness of 50 μm is laminated on the entire surface of the base material layer 1 printed with the card number 7 with a urethane-based adhesive or the like, and then cut at a predetermined position. And let it be in a single wafer state. Next, the easily peelable hiding layer 4 is formed by solid printing using a hiding ink by a silk screen method so as to cover the entire printed card number 7. Further, a tint block printing layer and a protective layer are formed in this order on the easily peelable hiding layer 4 surface. The tint block printing layer and the protective layer are formed by offset printing or silk screen printing. Finally, a card having an easily peelable concealing layer is completed by cutting at a predetermined position.
