| description | PROBLEM TO BE SOLVED: To eliminate unevenness on the surface and make the fiber layout pattern undetectable from outside so as to prevent forgery and alteration, by causing a magnetic card to have a multilayer structure including a white polyester layer containing a magnetically sensitive fiber of a thermoplastic resin. SOLUTION: This magnetic card includes a white polyester layer 1 containing a magnetically sensitive fiber of a thermoplastic resin, and a white polyester layer 2 containing fine cavities adhered to the layer 1 via an adhesive layer 3. In this case, it is preferred that the thermoplastic resin composition is a polyester resin which is not deformed or warped at a temperature of 80 deg.C or higher, is consideration of safety in storing and handling the card. Particularly, it is preferred the thermoplastic resin composition is polyethylene terephthalate of 80wt.% or more in view of characteristics and economy. By causing the magnetic card to have a multilayer structure, unevenness on the surface of the card made of the magnetically sensitive fiber, the layout of which is not reproducible, is eliminated, and reading of proper information is ensured. At the same time, the fiber layer pattern is made undetectable from outside, thus preventing forgery and alteration. |
