ABSTRACT:
An information recording-displaying card, includes: a core sheet; and an over sheet bonded to the core sheet, including: a support including an amorphous polyester resin, and a reversible thermosensitive recording layer disposed on the support, including: an electron-donating coloring compound, and an electron-accepting compound. The reversible thermosensitive recording layer is capable of relatively forming a coloring state and a decolorizing state, with a difference in at least one of heating temperature, and cooling rate after heating. The over sheet is embossable in an upper portion thereof, functions as an image displaying section, and meets the following condition (A) and condition (B): (A) (the over sheet's upper limit temperature for erasing −30° C.)≦(temperature of a storage elasticity E′ (1.0 E+08) Pa)≦200° C., and (B) 1.0 E+04 Pa≦(the storage elasticity E′ of the over sheet at 180° C.)≦5.0 E+07 Pa.
