To provide an information recording-displaying card that is easy tonemboss and is so excellent in durability as not to cause deformation evennafter repeated formings and erasings of an image: n An information recording-displaying card, includes: a core sheet; andnan over sheet bonded to the core sheet, wherein the over sheet includes: ansupport which includes an amorphous polyester resin, and a reversiblenthermosensitive recording layer disposed on the support, wherein thenreversible thermosensitive recording layer includes: an electron-donatingncoloring compound, and an electron-accepting compound, wherein thenreversible thermosensitive recording layer is capable of relatively forming ancoloring state and a decolorizing state, with a difference in at least one of thenfollowing: a heating temperature, and a cooling rate after a heating, andnwherein the over sheet is embossable in an upper portion thereof, functionsnas an image displaying section, and meets the following condition (A) andncondition (B): condition (A) (the over sheet's upper limit temperature fornerasing - 30°C) ≤ (a temperature of a storage elasticity E' (1.0 E + 08) Pa) ≤n200°C, and condition (B) 1.0 E + 04 Pa ≤ (the storage elasticity E' of the overnsheet at 180°C) ≤ 5.0 E + 07 Pa. |
