INFORMATION RECORDING/DISPLAYING CARD, IMAGE PROCESSING METHOD USING SAME, AND IMAGE PROCESSOR

摘要

To provide an information recording-displaying card that is easy to emboss and is so excellent in card's machinability (by bonding to a thick base material of a reversible thermosensitive recording medium) and in eraseability: 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 relatively 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 erasing - 30 DEG C) > (the over sheet's temperature of a storage elasticity E' (1.0 E + 08) Pa), condition (B) 10 mu m or less of a surface waviness WCM, and condition (C) 1.0 E + 02 Pa≤(the storage elasticity E' of the reversible thermosensitive over sheet at 180 DEG C)≤5.0 E + 07 Pa.
