Abstract
A reversible thermosensitive recording medium includes a reversible thermosensitive recording layer including a matrix resin and an organic low-molecular-weight material dispersed in the matrix resin, of which transparency is reversibly changeable depending upon the temperature thereof, and having (1) a transparentizing upper-limit temperature of 125° C. or more, (2) a temperature difference of 20° C. or less between said transparentizing upper-limit temperature and an opaqueness initiation lower-limit temperature, and (3) a transparentizing initiation temperature of less than 95° C., and a method of recording and erasing images, using the recording medium, a method of producing the recording medium, and the application thereof a card, a label, writable or rewritable disk cartridge, disk and tape cassette are proposed.
