Abstract

(57) [Summary] [Purpose] Colored printing that makes the anti-counterfeiting function more reliable enables identification by ticket type, and also prevents corrosion of the metal vapor deposition layer. [Structure] A substrate, a magnetic recording layer laminated on the substrate, a coloring layer provided on the magnetic recording layer, and a heat-sensitive destruction type or discharge breakdown type metallic printing layer provided on the coloring layer, And a protective layer that covers the metal printing layer.

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a magnetic recording type prepaid card. Particularly, it relates to a prepaid card having an excellent anti-counterfeit function.

[0002]

[Prior art]

 Heretofore, Sn vapor deposition cards have been known as prepaid cards provided with a heat-sensitive destruction type or discharge destruction type metallic printing layer, and A1 vapor deposition cards etc. have been known as discharge destruction type recording media. The heat-sensitive destructive metal printing layer is a part of a metallic print layer that melts when heat energy of a predetermined level or higher is applied to a predetermined shape, and is attracted to the surrounding low-temperature part by surface tension so that the predetermined shape becomes permanent. It is a metal layer that produces through holes. The electric discharge destruction type metal printing layer is a metal layer which gives similar results when electric discharge is used instead of heat.

Further, as a conventional magnetic card having both a magnetic recording / reproducing function and a printing function, a magnetic layer is formed on a base material such as a polyester film, and a heat-sensitive destruction type or discharge breakdown type metal is formed on the magnetic layer. A product provided with the above metal vapor deposition layer is used as a printing layer. The present invention relates to a prepaid card having a heat-sensitive destruction type or discharge destruction type metal printing layer of this type. The prepaid card having such a double recording layer requires a double recording and reproducing means, and thus can improve the forgery prevention function.

[0004]

[Problems to be solved by the device]

 However, these conventional printable prepaid cards have problems that they are not sufficient for forgery prevention, that the metal-metal vapor deposition layer is less likely to corrode, and that it is difficult to identify the ticket type.

Therefore, an object of the present invention is to provide a prepaid card which can be identified by the type of ticket by colored printing that further ensures the forgery prevention function and, at the same time, prevent corrosion of the metal vapor deposition layer. Is.

[0006]

[Means for Solving the Problems]

 The above problems can be solved by the technical means of the present invention. That is, in the present invention, a base material, a magnetic recording layer laminated on the base material, a coloring layer provided on the magnetic recording layer, and a heat-sensitive destruction type or discharge breakdown type provided on the coloring layer. It is characterized by having a metal printing layer and a protective layer covering the metal printing layer.

[0007]

[Action]

 According to the present invention, a colored layer is provided between the heat-sensitive or electric discharge destruction type metal printing layer and the magnetic recording layer, so that the magnetic metal in the magnetic recording layer, the magnetic oxide and the metal of the metal printing layer are separated from each other. Corrosion can be prevented by suppressing the electrochemical reaction of.

[0008]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 is a base material for a prepaid card. As the base material 1, a polyester film such as polyethylene terephthalate is used.

A magnetic layer 2 for magnetic recording in which magnetic powder is uniformly dispersed in a binder is laminated on a substrate 1, and a continuous colored layer 3 of a single color, a heat-sensitive destruction type metal printing layer 4, are formed on the magnetic layer 2. And the transparent protective layer 5 is laminated. When the heat-sensitive destructible metal printing layer 4 is destroyed by heat into a predetermined printing die, the colored layer 3 in that portion can be seen through. Further, since the magnetic layer 2 and the metal print layer 4 are separated from each other, there is no problem of corrosion. The metal printing layer is of a thermal destruction type or a discharge destruction type and is laminated by vapor deposition.

[0010]

[Effect of device]

 By providing the colored layer, the printed part formed by the destruction looks colored. Therefore, it is more effective in preventing forgery. By providing different colored zones on the same ticket and selectively destroying it depending on the ticket type, it becomes possible to distinguish the ticket types by color.
