A reversible thermosensitive recording medium has a support, a reversible thermosensitive recording layer of which color tone is reversibly changeable with the application of heat thereto, and a printing layer bearing a printed image A. When an image B is formed in the reversible thermosensitive recording layer by heating the recording layer, the image B completes a single composite image in combination with the printed image A. The method of using the above-mentioned recording medium includes the step of forming an image B in the reversible thermosensitive recording layer by heating the recording layer to an image formation temperature to complete a single composite image in combination with the printed image A.

Method of using reversible thermosensitive recording medium and the reversible thermosensitive recording medium

A reversible thermosensitive recording medium is provided, comprising a supporting substrate, a reversible thermosensitive recording layer and an overcoat layer, formed in the order recited, in which the recording layer changes transparency or color tone reversibly with temperature. The overcoat layer is formed to have a peak temperature of at most 155&deg; C. in a tan &dgr; vs. temperature curve, wherein tan &dgr; is defined by G&prime;/G&Prime;, with dynamic modulus of elasticity represented by G&prime; and dynamic elastic loss represented by G&Prime;. This thermosensitive recording medium is capable of satisfactorily carrying out the formation and erasure of images with a heating device, such as a thermal printhead, and overcoming difficulties such as the occurrence of cracks and portions of the overcoat layer being removed therefrom and then sticking to heating elements of the thermal printhead, which are caused especially by the application of heating pulses for shorter periods of time and/or at increased pressures during repeated image formation and erasure processing.
