Abstract

PURPOSE:To enhance durability by providing a coating layer having a ceramic thin film layer in at least a part on a magnetic recording layer. CONSTITUTION:A coating layer 7 containing at least a ceramic thin film layer 5 is formed in the magnetic recording layer 3 side of a highly durable magnetic card 1 via an adhesive 4 in a part or the whole face of a card substrate 3 so as to be overlapped on the magnetic recording layer 3. Thereby the magnetic recording layer 3 is concealed. The coating layer 7 is provided with a decorative layer and a hologram layer besides the ceramic thin film layer 5. Further thickness of the coating layer 7 is set to 10mum or below. A transfer method depending on a transfer sheet is applied to formation of the coating layer 7. The transfer sheet is constituted by laminating a release layer, the ceramic thin film layer 5 and the adhesive layer 4 on a base film such as polethylene terephthalate.

2. Description of the Related Art Conventionally, it has been difficult to say that a card having a magnetic recording layer on its surface has a bad magnetic appearance and is excellent in design because the color of the magnetic recording layer is black or brown. Therefore, a so-called concealing card in which a concealing layer is provided to hide the magnetic recording layer is generally used. This concealing layer is formed mainly by a printing method using a coloring ink or an ink containing metal powder such as aluminum.

However, the concealing layer formed by printing with the ink is inferior in durability such as abrasion and scratch on the ink surface, and usually covers the outermost surface with an OP varnish containing no colorant, or is exposed to ultraviolet rays. The durability of the surface has been improved by forming a protective layer using a curable resin (Japanese Patent Laid-Open No. Hei 3).
-270991). However, durability is often insufficient even with such a method. It is also possible to improve the durability by thickening the printed layer, but if the thickness of the layer provided on the magnetic recording layer increases,
There is a problem that reading of magnetically recorded information is hindered.

The present invention will be described in more detail with reference to specific examples. Example 1 Using a polyethylene terephthalate film having a thickness of 25 μ as a base film 8, an acrylic resin dissolved in a solvent was coated on the film by a known coating method and then dried to obtain a release layer 6 having a thickness of 0.5 μ. Corona discharge treatment was performed on the surface on which the release layer 6 was formed, and then a ceramic thin film layer 5 of titanium dioxide (TiO 2 ) was formed into a thin film having a thickness of 400 Å by a vacuum deposition method. Next, by superposing on the ceramic thin film layer 5, a coating liquid as a heat seal agent containing 100 parts by weight of acrylic resin and 10 parts by weight of microsilica was reverse coated by three reverse coating so as to have a thickness of 3 μm when dried. Transfer foil 1 by applying and forming adhesive layer 4
Got 4. On the other hand, a card substrate 2 made of polyvinyl chloride, which has a stripe-shaped magnetic recording layer 3 having a thickness of 0.76 mm and a width of 6 mm and which conforms to the JIS standard, was prepared. The magnetic recording layer 3 side of the card base 2 and the adhesive layer 4 side of the transfer foil 14 are superposed on each other and heated and pressed, and then the polyethylene terephthalate film 8 is peeled off to form the ceramic thin film layer 5. Transfer and form on the card base 2,
The highly durable magnetic card 1 of the present invention was obtained. The thickness of the magnetic recording layer of this card 1 was 3.5 μm. The card 1 has a good magnetic read output. Furthermore, the wear resistance to the magnetic head is also good, and the reading operation is 1000 times.
Even if it was repeated, there was no problem in reading and scratches on the surface were slight.

As described above, the highly durable magnetic card of the present invention obtained by transferring and forming the ceramic thin film layer for concealing the magnetic layer is formed on the magnetic recording layer of the magnetic card. The total thickness of each layer, including the ceramic thin film layer,
Since the magnetic layer printed by the conventional printing method can be made extremely thin as compared with the concealed printed layer, the magnetic recording can be read without any trouble. Moreover, since the magnetic recording layer is protected by the ceramic thin film layer, the contact with the magnetic head when reading the magnetic recording and the durability against temperature, humidity, acid, alkali and the like are improved. Further, since a ceramic thin film layer is formed on the surface of the magnetic recording layer instead of a printing layer mainly composed of a synthetic resin-based binder as in ink printing, it does not dissolve in a solvent and is resistant to solvent. Are better. Therefore, it is possible to prevent forgery and unauthorized use of the magnetic card. Also,
The decorative layer and the hologram layer, which are provided on the ceramic thin film layer, have effects such that the design of the magnetic card of the present invention having a thin ceramic thin film layer can be improved.
