Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a magnetic card having a magnetic recording layer such as a credit card, a bank cash card, an identification card and the like.

[0002]

2. Description of the Related Art Magnetic cards having a magnetic recording layer provided on a substrate made of a thermoplastic resin are widely used as credit cards, bank cash cards, identification cards, refueling cards and the like. These conventional magnetic cards use a thermoplastic resin such as vinyl chloride as a base material, and the magnetic recording layer is called a magnetic stripe. A magnetic layer on a PET (polyethylene terephthalate) tape or the like is stripe-shaped on a desired portion on the base material. It is formed by heat-transferring or laminating. In this layer structure, the magnetic stripe limits the printed surface of a character pattern or the like, and also limits the degree of freedom in design, which impedes high designability. Recently, in order to increase the degree of freedom of this design, there are many magnetic cards in which a concealing layer is provided on the entire surface of the base material on which the magnetic stripe is transferred, and characters or patterns are printed on the concealing layer to protect the printing. Has become. However, in order to form the masking layer that masks the magnetic stripe, a special masking technique for masking a step or a color difference between the magnetic stripe and the substrate surface is required, which hinders improvement in productivity. Further, there is a demand for improvement in terms of production cost, such as difficulty in alignment when transferring or pasting the magnetic stripe and alignment when cutting the card, resulting in poor yield. Therefore, a method of manufacturing a magnetic card has been proposed which solves the above problems by sequentially forming a magnetic recording layer and a concealing layer on the entire surface of a magnetic card substrate (Japanese Patent Laid-Open Publication No. 54-73608, Japanese Patent Laid-Open No. 2hei 73-608). -2496
96, JP-A-6-28660). According to these methods, a special concealment technique is not particularly required, and the accuracy of alignment is further improved, but there are many types of sheets that make up the card, and there is a heat pressing step in the manufacturing process, which takes time. This is an obstacle to productivity improvement and there are points to be improved.

[0003]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to simplify the manufacturing method of the conventional magnetic card by using a single type of sheet constituting the magnetic card and omitting the hot pressing step, and to improve the productivity. It is to provide an inexpensive and stable magnetic card of stable quality.

Then, the protective layer is transferred to produce a magnetic sheet, and then a printing layer and a protective layer are sequentially formed on the other surface and punched into a predetermined size of a magnetic card to provide a magnetic recording layer of the magnetic sheet. The method for producing a magnetic card is characterized in that the print layer and the protective layer on the non-exposed side are formed by transfer.

The manufacturing process of the magnetic card according to the present invention will be described below with reference to the drawings. First, a method of manufacturing a transfer film for transferring the magnetic recording layer and the hiding layer to the thermoplastic resin sheet base material will be described. The protective layer 3 is formed on at least one surface of the release film 1 made of a thermoplastic resin having a release effect on the entire surface 2 having a release effect by a conventionally known coating method such as a gravure method, a roll method or a knife edge method. It is formed so that the thickness after drying is 0.1 μm to 2 μm, preferably 0.5 to 1.5 μm. Next, on the protective layer 3, a printing layer 4 for characters and patterns necessary for a magnetic card is formed.

The thermoplastic resin sheet 8 used as the base material is preferably a hard vinyl chloride sheet, has a thickness of 0.6 mm or more, and has a total thickness of 0.7 to 7 after transferring the magnetic recording layer, the hiding layer, the printing layer and the protective layer. A plate-shaped member selected to have a length of 0.8 mm is used. The size in the vertical and horizontal directions is appropriately selected in consideration of the printing process and the number of cards to be punched. To bond the transfer film 10 and the thermoplastic resin sheet base material 8 together, the transfer film 1
The adhesive layer 7 is provided on the entire surface of the magnetic recording layer 6 of No. 0 by a conventionally known method, and the entire surface of the base material 8 is pressure-bonded by a roll and laminated (FIG. 2). If a magnetic recording layer is required on both sides of the magnetic card, the transfer film 1 is applied on both sides of the base material 8.
It is sufficient to stick 0. At this time, it is desirable to bond the both surfaces at the same time from the viewpoint of man-hours and costs, but if it is impossible to bond the both surfaces at the same time due to the structure of the machine, they may be bonded one surface at a time. At this time, since the transfer film 10 has a roll shape and the thermoplastic sheet base material 8 has a plate shape, for example, the thermoplastic resin sheet base material 8 as shown in FIG.
It is advisable to carry out the laminating process while continuously transporting with a belt or a roll.

(Fig. 3b). Finally, the magnetic sheet was punched into a predetermined card size to produce a magnetic card.

<Example 3> In the same manner as in Example 2, a transfer film for a surface pattern of a magnetic card provided with an adhesive layer was produced. In addition, a protective transfer layer and a printing layer for a back handle were sequentially laminated on the entire release-treated surface of the release-treated 38 μm PET film to prepare a transfer film for printing. An adhesive layer was also provided on the print layer of this transfer film for printing. The printing transfer film provided with this adhesive layer was used in place of the backing transfer film of Example 2, and the magnetic sheet 14 (FIG. 3c) was manufactured in the same manner as in Example 2. Finally, the magnetic sheet was punched into a predetermined card size to produce a magnetic card.
