    摘要: A reversible thermal recording method using a color/non-color type reversible thermosensitive recording material which has a recording layer formed overlying at least one side of a substrate and including an electron donating coloring agent and an electron accepting color developer and which reversibly forms a colored state and a non-colored state by being appropriately heated and cooled. The recording layer having images of the colored state which have been formed in the recording layer is heated to erase the image, and imagewise heated either at substantially the same time as, or after, the image erasing operation to record new images therein, and then relatively rapidly cooled to maintain the new images. A reversible thermal recording apparatus therefor is also provided.

    摘要: A reversible thermosensitive recording medium is disclosed which includes an opaque support and a transparent recording film having a thermosensitive layer capable of reversibly assuming a maximum transparent state and a maximum opaque state depending upon the thermal hysteresis thereof. The recording film has an image display section in which a void space is provided between the recording film and the opaque support and a color discriminative from the color of the support. The display section in the maximum transparent state shows a reflectance greater by 5% than that in the maximum opaque state and a transmittance of 20-80% in the maximum transparent state, so that the visibility of the recorded image is improved.

    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.
