Patent ID: 6969695

Claim:
An information recording-displaying card, comprising: a core sheet; and an over sheet bonded to the core sheet, wherein the over sheet comprises: a support which comprises an amorphous polyester resin, and a reversible thermosensitive recording layer disposed on the support, wherein the reversible thermosensitive recording layer comprises: an electron-donating coloring compound, and an electron-accepting compound, wherein the reversible thermosensitive recording layer is capable of forming a coloring state and a decolorizing state, with a difference in at least one of the following: a heating temperature, and a cooling rate after a heating, and wherein the over sheet is embossable in an upper portion thereof, functions as an image displaying section, and meets the following condition (A), condition (B) and condition (C): condition (A) (the over sheet's upper limit temperature for erasingâˆ’30Â° C.)>(the over sheet's temperature of a storage elasticity Eâ€² (1.0 E+08) Pa), condition (B) 10 Î¼m or less of a surface waviness, and condition (C) 1.0 E+02 Paâ‰¦(the storage elasticity Eâ€² of the reversible thermosensitive over sheet at 180Â° C.)â‰¦5.0 E+07 Pa.
