PROBLEM TO BE SOLVED: To provide a reversible heat sensitive recording material, the printing on which can be erased with a thermal head. SOLUTION: This recording material is mainly made of a polymer resin matrix and an organic low molecular compound scattered in the polymer resin matrix so as to realize the development of a reversible change due to temperature between a transparent state and anopaque state. In addition, the organic low molecular compound at least includes a thioether and an aliphatic dibasic acid. In this case, the thioether has a 10-30C alkyl group. At the same time, the aliphatic dibasic acid has a 4-26C alkyl group. |
