層を設けるようにしている。In this type of magnetic card, the substrate itself is thick, so it is not possible to continuously form a magnetic layer by winding it into a roll like magnetic tape.
For this reason, it is usually produced by using magnetic tape for transfer, cutting it to an appropriate size, and then thermally transferring it to the desired area on the board in the form of stripes. In order to improve the magnetic stripe's appearance and to make it difficult to distinguish its position, a desired design is further printed on or around the magnetic stripe, or a concealing layer is provided.

のであることを知り、この発明を完成するに至った。[Means for Solving the Problems] As a result of intensive studies to achieve the above object, the inventors have developed a thin and flexible overcoat for producing a thick magnetic card with a total thickness of 0.4 f1 or more. By using a sheet, a magnetic layer and a pattern layer thereon are sequentially formed on the entire surface of one side of the sheet, and this is laminated on the entire surface of at least one side of the substrate with the oversheet facing inside. Also, instead of using the above-mentioned oversheet and substrate, two flexible sheets are used, and a magnetic layer and a pattern layer thereon are sequentially formed on the entire surface of one side of both sheets. It was discovered that by laminating the cards in such a manner that thick magnetic cards with stable quality and low cost could be produced very easily, and this led to the completion of this invention.

ミネート材を作製した。Example 3 Two polyvinyl chloride sheets with a thickness of 0.31 tm were used as flexible sheets, and on one side of both sheets, a 14 μm thick magnetic layer, a 3 μm thick hiding layer, and a 2 μm thick pattern with the same configuration as in Example 1 were provided. Two laminates were created by forming the layers one after the other.
