PURPOSE:To obtain a reversible image having excellent contrast and resolution and capable of being repeatedly used without any deterioration of image quality, by printing under pressure on a reversible recording material having a recording layer comprising an organic low molecular weight substance dispersed in a resin matrix. CONSTITUTION:A solution of a resin matrix and an organic low molecular weight substance is applied to a base such as a paper, a plastic film, a glass plate and a metallic plate, followed by drying to provide a recording layer, thereby obtaining a reversible recording material. A solvent used for preparing the solution is carbon tetrachloride, ethanol, toluene, benzene or the like. Resin used as the resin matrix is polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, silicone resin or the like. The organic low molecular weight substance may be any one which is changed from a polycrystal to a single crystal under pressure in the recording layer, and one which has a melting point of generally 30-200 deg.C, preferably, about 50-150 deg.C is used. The organic low molecular weight substance may be, for example, carboxylic acid ester of Alkanol or thioalcohol. |
