<P>PROBLEM TO BE SOLVED: To provide a reversible thermal recording medium which exerts good color development properties and erasability even in repetition, and which has excellent durability. <P>SOLUTION: In this reversible thermal recording medium, a reversible thermal recording layer, which contains a reversible thermal composition capable of forming the state of relative color development by virtue of a heating temperature and/or a difference between cooling speeds after heating by using an electron-donating coloring compound and an electron-accepting compound, is provided on a substrate; and an underlayer including hollow particles and a hardening resin in a crosslinked state is provided between the substrate and the recording layer. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
