Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic card in which a magnetic tape (magnetic recording layer) provided on a credit card, a cash card, an ID card, etc. is concealed, and the uppermost surface protective layer is a magnetic tape upper layer portion. The present invention relates to a concealment card provided by being divided into upper layers of non-magnetic tape.

2. Description of the Related Art Conventionally, a plastic sheet is used as a core base material, and thin plastic films (31, 31) are laminated on both sides of the core base material (30), and one plastic film (3
1) In a magnetic card in which a magnetic tape (32) is attached onto the magnetic tape and heat pressed to make it flush, for example, a first colored concealing layer (33) and a second pattern layer (on the magnetic tape and / or around the magnetic tape). 34), and a thermoplastic resin layer (35) is provided on both layers to form a surface flush by hot pressing from above to conceal the magnetic tape and at the time of writing and reading data on the magnetic tape. ,
A card having increased durability against a magnetic head (see FIG. 2) is known from Japanese Utility Model Publication No. 1-39577. In addition, as shown in FIG. 3, a magnetic card (50) in which a concealing layer (33), a pattern layer (34), and a surface protective layer (35) are provided on the entire surface of the magnetic card to conceal the magnetic tape (32) is often seen recently. Be done.

As described above, the card in which these magnetic tapes are concealed is provided in order to hide the color of the magnetic material of the magnetic tape and to utilize the entire surface of the card as a pattern layer. In addition, the surface protection layer is to prevent abrasion and damage due to writing and reading of the magnetic head when using a magnetic tape or a pattern layer for the card, and also to prevent cracks on the surface of the magnetic card due to embossing during manufacturing. It is intended to enhance durability.

[0004]

As described above, as a quality function of the surface protective layer, abrasion resistance with respect to the magnetic head is required, and with respect to the external environment, heat resistance, moisture resistance, and
Durability such as chemical resistance is required. In addition, the top layer of the non-magnetic tape surface, especially the area of the embossing (E), has flexibility that does not cause cracking of the card surface due to embossing, and also has excellent inking property (thermal transfer of colored transfer foil) to the embossed surface. Required to be present. However, as shown in FIG. 3, the conventional surface protection layer (35) is hard and flexible in order to satisfy the required quality of both the top layer of the magnetic tape area and the top layer of the non-magnetic tape area. The intermediate surface protective layer (35) having the property of being provided is provided. For example, a thermoplastic resin such as vinyl chloride acetate resin, an acrylic resin, a urethane resin and a thermosetting resin to some extent were used, but all of them are intermediate surface protective layers for the required quality. The wear resistance of the uppermost layer in the magnetic tape area has been a problem. Therefore, the present invention provides a concealing card that satisfies the required quality by separately providing a surface protective layer having surface abrasion resistance and a surface protective layer having flexibility.

[0005]

In order to solve the problems, the present invention uses a plastic sheet as a core substrate as shown in FIG.
(10) As a plastic film on both sides of the core substrate
(11,11) are laminated and the plastic film (1
1) A magnetic tape (12) is attached on top and a magnetic card (K) with both sides flush is formed by heat pressing, and a colored hiding layer (13), a pattern layer (14), and a surface protection layer are formed on top of it. A card in which a magnetic tape (12) is concealed by providing (15), the surface protection layer (15)
Is provided by being divided into the uppermost layer portion of the magnetic tape area and the uppermost layer portion of the non-magnetic tape area, and the uppermost layer portion of the magnetic tape area is a surface protective layer (15A) made of a thermosetting resin.
The top layer of the non-magnetic tape area is a concealment card (20) having a surface protection layer (15B, 15B) made of a thermoplastic resin.

A detailed description will be given with reference to the drawings. FIG. 1 is a partial cross-sectional view of a concealing card in which a surface protection layer is separately provided according to an embodiment of the present invention. As shown in FIG. 1, the top layer of the magnetic tape area on the pattern layer (14) of the magnetic card (K) is a surface protective layer made of a thermosetting resin wider than the width of the magnetic tape (12).
A concealment card (20) is provided with (15A) and a surface protection layer (15B, 15B) made of a thermoplastic resin on the uppermost layer of the non-magnetic tape area, and both surfaces are made flush by hot pressing. That is,
The uppermost surface protection layer (15A) in the magnetic tape area is coated with a thermosetting resin.The resin with high wear resistance is appropriately selected for the magnetic head to perform flushing. It is a thing. In addition, a thermoplastic resin is appropriately selected for the uppermost layer of the non-magnetic tape area, and a highly flexible surface protective layer (15) is provided to prevent cracking of the card surface during embossing.
B, 15B) is provided, which is a concealment card (20) that can satisfy the quality requirements of both parties.

[0007]

As shown in FIG. 1, the concealing card (20) of the present invention has a surface protective layer (15A) provided on the uppermost layer of the magnetic tape area.
Thermosetting resin for the non-magnetic tape area, the thermoplastic resin is provided separately for the surface protection layer (15B, 15B) provided on the top layer of the non-magnetic tape area, and by performing the flushing of both sides by hot pressing, Each area serves as a surface protection layer (15) having high wear resistance and flexibility. As a result, the uppermost layer of the magnetic tape area can minimize the generation of foreign matter due to scratches and surface abrasion due to writing and reading by the magnetic head, and can increase the durability of the concealed card and extend the service life. .. In addition, the uppermost layer of the non-magnetic tape area is made of a flexible thermoplastic resin during embossing,
This prevents cracking of the embossing area (E) on the surface of the concealed card and improves the inking property of the colored transfer foil by thermal transfer to the surface of the embossed character.
