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.

摘要： A method of compensating for the distortion in a recording layer of a reversible thermosensitive recording medium, for which transparency of the recording layer is changeable, depending upon the temperature thereof, and the recording layer is capable of forming images and erasing the images reversibly. The distortion in the recording layer is caused by the repeated image formation by image formation means and/or image erasure by image erasing means. In this method, stress is applied to the recording layer before and/or after image formation by the movement of the recording medium relative to the image formation means, in a direction different from the direction of the application of stress in the course of a previous image formation or image erasure. Instead of the stress, thermal energy can be employed for compensating for the distortion in the recording layer.
