[0006]

[Preferred Embodiment]

 Next, the present invention will be described in more detail with reference to preferred embodiments. The configuration of the present invention will be described in detail with reference to the accompanying drawings illustrating an embodiment of the present invention. FIG. 1 is a plan view of an example of a cash card of the present invention, FIG. 2 is a schematic sectional view taken along line AA 'of FIG. 2, and FIG. 3 is an example of the manufacture of the card of the present invention. It shows. 1 to 3, 10 is a cash card, 1 is a magnetic recording layer, 2 is a temporary recording area which is the main feature of the present invention, and 3 to 4 are patterns of other characters or figures. . In FIGS. 2 and 3, 5 is the top coat layer of the card, 6 is the center layer, and 7 is the protective layer on the back surface.

In FIGS. 1 to 3, any one of various conventionally known cards is known except that a temporary recording area 2 and the recording area 2 which characterize the present invention are formed on the magnetic recording layer 1. Also, a method of manufacturing the card itself is known. Therefore, the structure of the temporary recording area 2 which characterizes the present invention will be described in detail below. The temporary recording area 2 is colored, erased or discolored by the thermal application of the pattern of a thermal head provided in an automatic teller machine of a financial institution or the like, and in the recording layer 2, according to the pattern of the thermal head, Arbitrary numbers, symbols, characters, etc. are displayed.After the displayed characters, etc. are confirmed by the user, they disappear promptly, and these symbols, etc. appear and disappear repeatedly. This is a possible configuration.

Such action and effect can be realized by forming the temporary recording area 2 from a material that reversibly develops, erases, or changes color by heat. A material generally called a thermochromic pigment is suitable as a material suitable for such a recording material. Suitable thermochromic pigments include, for example, silver, copper, mercury, iodine compound-based complex salts or double salts, and these thermochromic pigments generally have a crystal structure in the range of −10 ° C. to 200 ° C. according to the change of temperature. As a result, the hue changes, and when the temperature returns to its original value, the hue also returns to its original value. As these thermochromic pigments, in addition to the above, organic compounds such as those containing an electron donor and an electron acceptor as the main components, and those containing a substance having a lactone ring as the main components can be similarly used. . All such thermochromic pigments are publicly known and can be easily obtained from the market. Further, instead of such a thermochromic pigment, a liquid crystal material that changes color or develops color at an appropriate temperature, a material that changes phase transparently and opaque repeatedly by temperature, and the like can be used as well. Further, by selecting the kind of the heat-sensitive material as described above, it is possible to adjust the information display time in the range of several seconds to several to several tens of hours.

In the present invention, such a thermochromic pigment is dispersed or dissolved in an arbitrary resin vehicle to prepare an ink or a paint, and the magnetic recording layer 1 of the card 10 or a protective layer formed on the surface thereof is used. The temporary recording area 2 may be formed by coating all or part of the surface of the metal thin film layer (not shown). As a preferable method, when various kinds of cards are formed, for example, as shown in FIG. 3, other necessary various kinds of printing 3 to 4 are applied to the central sheet 6 of the card, and the surface of the top coat layer 5 is subjected. On the surface of the magnetic layer 1 thus formed, a thermoplastic resin film or sheet 2 containing a thermosensitive material such as a thermochromic pigment dispersed or dissolved therein is placed, and three layers are formed together with the coating layer 7 on the back surface. At the same time, press molding is performed to make the surface of the card smooth as shown in FIG. Further, in such a temporary recording area 2, an arbitrary pattern is formed on the release paper with a printing ink or paint containing a thermochromic pigment, and this is transferred onto the magnetic recording layer of the card by various methods. But the effect is the same. Further, the configuration of the card 10 is not limited to the mode shown in FIG. 2, and for example, the temporary recording area 2 is formed on the magnetic recording layer 1 of the surface sheet 5, and another pattern is formed if necessary. May be formed, and a thin top coat layer that does not hinder the conduction of heat from the thermal head may be formed thereon. In the present invention, the temporary display area can be arbitrarily formed on the back surface of the card as long as it has the above configuration.

[0010]

【Example】

Next, the present invention will be described more specifically with reference to examples. The required patterns 3 to 4 were printed on both sides of a white hard polyvinyl chloride sheet 6 of 85.6 mm × 54 mm × 0.56 mm. A thermochromic pigment that changes its color from red to black at 50 to 55 ° C by the transfer method on the surface of the magnetic recording layer of the transparent hard polyvinyl chloride film 5 having the same size and the thickness of 0.1 mm and the magnetic recording layer is formed. A temporary recording area 2 formed of a paint containing These sheets 5 and 6 and a hard polyvinyl chloride film 7 having the same size and a thickness of 0.1 mm are stacked as shown in FIG. 3 and heat-pressed at a temperature of 140 to 160 ° C. to obtain the cache shown in FIG. I got a card 10 . When heat was applied literally to the temporary recording area 2 of the card 10 by the thermal head, clear black characters appeared, and after about 5 minutes, these characters disappeared completely. This coloring and decoloring can be repeated. Although PVC is used as the material for the card in the above, instead of PVC, for example, polyester, polyurethane, polyolefin, polycarbonate, or other materials can be used, and the temperature-indicating pigment can be used at various temperatures. A thermochromic pigment that develops, discolors or disappears can be used. The characteristic configuration of the present invention has been described above by taking the cash card as shown as an example, but the present invention is not limited to such an example, and various types of times such as telephone cards, medical care cards, highway cards, etc. can be used. The present invention is naturally applicable to a ticket and other magnetic recording cards for similar uses, and a temporary recording card for these uses is naturally included in the scope of the present invention.

[0011]

【effect】

 As shown in the above examples, the present invention displays numbers, characters, symbols, etc. on at least a part of the surface of the magnetic recording layer of a card by reversibly discoloring, coloring or erasing by heat as described above. It is possible to do so, and the displayed symbols etc. are quickly erased as the temperature returns after use. For example, by incorporating a recording device with a thermal head into an automatic teller machine of a financial institution, the information required by the user is displayed during use, and after the user confirms the information, the information can be displayed for several seconds. It is automatically erased within hours, ensuring complete confidentiality of information. Therefore, the conventional content confirmation method using a piece of paper becomes unnecessary. Further, in addition to the above effects, the present invention makes it possible to efficiently use the surface of a card having a small surface area by forming a temporary recording area on the magnetic recording layer so as to protect the magnetic recording layer. In the case of a transparent temporary recording area that can double as a layer and can hide the dark color of the magnetic recording layer, it is possible to display with the magnetic recording layer as the background. When the metal thin film layer is present between the recording area and the recording area, various effects such as display with excellent metal gloss can be obtained.
