    摘要: 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° C. in a tan &dgr; vs. temperature curve, wherein tan &dgr; is defined by G′/G″, with dynamic modulus of elasticity represented by G′ and dynamic elastic loss represented by G″. 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.
