Description of the Related Art Conventionally, as a magnetic card, a coil-shaped support such as paper or plastic film is continuously coated with a coating material in which a magnetic material is dispersed by a coater and dried to obtain a magnetic recording layer. Further, in order to protect and conceal the magnetic recording layer, a non-magnetic material such as aluminum paste or carbon is dispersed in a solvent in which a polyester-based, polyurethane-based, acrylic-based resin or the like is dissolved, and a paint is applied and dried. To obtain a protective layer. This is cut into a card shape to obtain a magnetic card.

ン印刷方式等により印刷される。However, in recent years, various methods have been adopted to obtain information peculiar to a card as a countermeasure against forgery and falsification. For example, in addition to conventional magnetic recording, there is a method of identifying a card by a magnetic bar code, an optical bar code or the like. In this case, the magnetic recording layer is applied to the entire surface of the support, whereas in pattern printing of a magnetic bar code or the like, the magnetic recording layer is partially printed on a specific place of the card. Is cut into sheets and printed by a screen printing method or the like.

が有効である。Since the above-mentioned aluminum paste or carbon paint cannot be applied to the single-piece support by a coater, it is protected by offset printing or screen printing after pattern printing of a magnetic bar code or the like. A hiding layer is formed. However, offset printing with UV ink (ultraviolet radiation curable ink) is generally effective in order to prevent an increase in spacing loss due to the thickness of the protective hiding layer.

るが、十分な強度は得られていない。In this type of offset printing, silver, black, etc. are generally used as the UV ink for the protective and concealing layer mainly for the magnetic recording layer. Adhesiveness, transfer of ink, etc. are uneven and there are many irregularities.
Overprinting is required. Further, the silver or black UV ink itself has a problem that the curing reaction is delayed due to the reflection and absorption of light, and an OP layer is further provided to maintain the strength of the coating film, but the sufficient strength is not obtained.

厚さ１μｍになるように印刷した。1 is a sectional view showing the construction of an embodiment of the present invention. A polyethylene terephthalate (PET) film having a thickness of 188 μm was used as the support 1, and a reverse coater was used to form a magnetic recording layer 2 in which a dry coating of 10 μm of Ba ferrite was dispersed. Next, using a 5% solution (solvent: MEK / toluene = 1/1) of a resin (Denka Vinyl # 1000CK, manufactured by Denki Kagaku Kogyo Co., Ltd.) on the magnetic recording layer 2 and drying with a gravure coater. An adhesive layer 3 having a film thickness of 1 μm was obtained. After overprinting on the adhesive layer with a UV ink (T & K TOKA No. 3 silver) to protect the silver-colored concealing layer 4 with an offset printing machine to a thickness of 3 μm, an OP layer (UVS CAR M OP varnish) was printed to a thickness of 1 μm.
