PURPOSE:To make visual information abundant by a method wherein an information display component of which transparency varies according to heat history, and a background component which has color corresponding to display information in a color vision information area according to display information recorded in a display information area are laminated. CONSTITUTION:A thermally reversible recording sheet 10 is made by laminating an information display component 11 and a background component 12. A display information area 13 and a color vision information area 14 are provided onto a recording sheet 10. The information display component 11 is composed of a recording material formed in a sheet form which has a known temperature-dependent shading property, and a protective layer. Further, the background component 12 is composed of a base material wherein resin materials of polyester or the like are used and a background layer. When the information display component 11 of the obtained thermally reversible recording sheet 10 is heated to a specific temperature and thereafter, cooled, since an area corresponding to display information is made transparent, a background component 12 having color corresponding to the display information is actualized. If the thermally reversible recording sheet 10 is taken as, for example, a prepaid card, color division of a prepaid sum of money will be able to be displayed. |
