Description

  The present invention relates to a card in which unique information and / or unique picture of a card is printed on an inner surface of an oversheet layer constituting the card by an ink jet recording method.

Conventionally, a card that can be recorded by an ink jet recording system using water-based ink is a magnetic card having a magnetic layer on a nonmagnetic support, and at least one surface of the magnetic card is hydrophilic to which water-based ink can be fixed. There is known a magnetic card (for example, see Patent Document 1) that has a surface and can be printed by an ink jet recording method using water-based ink.
Japanese Patent Laid-Open No. 9-48189

  However, in the above magnetic card, after the main body of the magnetic card is manufactured, the hydrophilic layer surface made of polyvinyl alcohol, colloidal silica, etc. formed on the surface of the nonmagnetic support of each magnetic card main body is inkjet-typed. A magnetic card is manufactured by printing, and there is a problem that a process of performing a predetermined print on an individual magnetic card body by an ink jet method becomes complicated, and a print layer printed by an ink jet method has a problem. Because it is on the surface of the magnetic card, there is a risk that the unique information and unique pattern of the magnetic card printed by the ink jet method during use of the card may be rubbed off or the unique information of the magnetic card may be falsified. have.

  An object of the present invention is to provide a card in which unique information and / or a unique pattern of a card is printed on an inner surface of an oversheet layer constituting the card by an ink jet recording method through an aqueous ink receiving layer during the card manufacturing process. It is to provide a card that can be manufactured at a low price even with a small number of cards because the manufacturing process is simple because the individual who owns the card can apply his / her favorite designs and designs. .

Over sheet layer is laminated on both surfaces of the core layer, the over-magnetic layer on one outer surface of the sheet layer is formed, photographs in regions which do not overlap with the magnetic layer of the inner surface of the magnetic layer one over sheet layer that is formed image, bar code, in card-specific information is printed on the card, such as numbers, aqueous ink-receiving layer is formed on the inner surface of at least said one of the over sheet layer, the unique information of the card of the inner surface of the over sheet layer in the water-based ink-receiving layer in the region excluding the area being printed, unique design of the card is a card which is characterized in that it is descriptor lint by the ink jet recording system.

Forming a magnetic layer on the surface of one of the oversheet layers where the aqueous ink-receiving layer is not formed, forming a water-based ink-receiving layer by coating on one of the two oversheet layers, The process of printing the card unique information and / or the card unique pattern on the surface of the water-based ink receiving layer formed on the oversheet layer by the ink jet recording system, and the ink jet recording system of one oversheet layer on one side of the core layer Superimposing the printed surface and superimposing the other oversheet layer on the other surface of the core layer, and heat-pressing and bonding the superposed oversheet layer and the core layer to produce a card laminate And a card having a step of punching the card laminated body into a predetermined shape at a predetermined position. This is a manufacturing method of the door.

  A method for producing a card as described above, comprising the steps of: forming a water-based ink receiving layer on the other oversheet layer by coating; and printing a unique pattern on the surface of the formed water-based ink receiving layer by an ink jet recording method.

  In the invention according to claim 1, during the card manufacturing process, the unique information of the card such as symbols, characters, and patterns and / or the unique pattern is printed on the inner surface of the oversheet layer constituting the card by the ink jet recording method. Yes, it is not necessary to produce and print offset-type or silk-screen-type printing plates at the time of card production, so that the production process can be simplified and even a small number of cards can be produced at low cost. .

  In the invention according to claim 2, the card can be a magnetic card having a magnetic layer.

  In the inventions according to claims 3 and 4, since the card unique information such as photographic images, bar codes, numbers, and / or unique patterns are printed on the inner surface of the oversheet layer, the printed layer is rubbed during use of the card. It is possible to prevent the card from being dropped due to the like, to prevent the unique information of the card from being altered and used, and to provide a card with a favorite pattern of the individual who owns the card.

  By using the manufacturing method of the present invention, during the card manufacturing process, the card's unique information such as photographic images, barcodes, numbers, and / or unique pictures are printed on the inner surface of the oversheet layer constituting the card. Since there is no need to create and print an offset or silkscreen printing plate at the time of card manufacture, the manufacturing process can be simplified and even a small number of cards can be manufactured at a low price. It can be produced.
