PURPOSE:To obtain a reversible thermal recording material applied with an antistatic treatment by incorporating a high-molecular cationic conducting agent in a thermal recording layer. CONSTITUTION:In a reversible thermal recording material provided with a substrate and thereon a thermal recording layer, which mainly consists of a resin base material and an organic low-molecular substance dispersed in said resin base material and changes in transparency reversibly according to a temperature, the thermal recording layer contains a high-molecular cationic conduction agent, or on the thermal recording layer an overcoat layer containing the high-molecular cationic conducting agent is provided. Namely, to impart an antistatic function, the high-molecular cationic conducting agent may be added in the thermal recording layer, or alternatively the overcoat layer containing the high-molecular cationic conducting agent may be provided on the thermal recording layer. Particularly, with the overcoat layer, an anti-stick function and correction properties are also obtained in addition to the antistatic function. When an image is formed by a heating means, the overcoat layer is brought into good contact with the heating means to improve a thermal sensitivity so as to form a sharp image. |
