<P>PROBLEM TO BE SOLVED: To provide a technique which enables a reversible thermosensitive recording material to be obtained from carbon dioxide as the raw material and to be an environmental-responsive product useful also from a viewpoint of protecting the global environment while the reversible thermosensitive recording material is excellent in slippage, non-stickiness and heat resistance, and has a slipping protective layer without surface scratches and head dregs adhesion even when image formation and erasure is repeated many times by a heating element. <P>SOLUTION: The thermosensitive recording material includes a thermosensitive recording layer, an optional intermediate layer and the slipping protective layer in this order on at least one surface of a base material. The thermosensitive recording layer is a reversible thermosensitive recording layer principally composed of a polymer resin and an organic low molecular substance dispersed in the polymer resin and having a transparency reversibly changeable by temperatures. Moreover, the slipping protective layer is formed of a resin composition which includes, as a principal component, a self-crosslinkable polysiloxane-modified polyhydroxy polyurethane resin which is derived from the reaction between a 5-membered cyclic carbonate polysiloxane compound and an amine compound and has a masked isocyanate group in its structure. <P>COPYRIGHT: (C)2013,JPO&INPIT |
