PROBLEM TO BE SOLVED: To eliminate discoloring of a printed image and skin even when a light such as solar light is emitted for a long time by providing a protective layer containing curable resin and organic ultraviolet absorbent on a reversible thermal recording layer containing curable resin including resin of a crosslinked state. SOLUTION: A protective layer containing curable resin and organic ultraviolet absorbent is provided on a reversible thermal recording layer. Recording layer contains curable resin containing resin of a crosslinked state. As the curable resin containing the resin of the crosslinked state and the curable resin used for the protective layer, resin having a group reacted with crosslinking agent such as carboxyl group, monomer having hydroxy group or carboxyl group or resin copolymerized with monomer except the previous monomer. As te organic absorbent, benzotriazole ultraviolet absorbent, benzophenone ultraviolet absorbent, salicylic acid ester ultraviolet absorbent or cyanoacrylate ultraviolet absorbent is used. |
