    摘要: A reversible thermosensitive coloring composition contains an electron-donating coloring compound and an electron-accepting compound, and is capable of reversibly assuming a color-developed state or a decolorized state depending upon the the temperature of the reversible thermosensitive coloring composition when heated, and/or the cooling rate of the reversible thermosensitive coloring composition when cooled after the heating thereof, with the electron-accepting compound being a compound of formula (I):A--R--X (I)wherein A represents a color-developing moiety; R represents an aliphatic hydrocarbon group comprising as the main chain thereof a straight chain hydrocarbon group having 8 or more carbon atoms, and may comprise a bivalent hetero-atom containing group and/or a bivalent aromatic group; and X represents a hetero-atom containing associative group. There is also provided a reversible thermosensitive recording medium comprising a support, and a thermosensitive recording layer formed thereon comprising the aforementioned reversible thermosensitive coloring composition.

    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 material which includes a recording layer including an electron donating coloring agent and an electron accepting coloring developer and in which an image is reversibly formed and erased by appropriately heating and cooling the recording layer, wherein the recording material has an image density retention not less than about 60% when the recording material having an image is allowed to settle in a dry place at 50.degree. C. for 24 hours, a residual image density not greater than about 0.03 when the recording material having an image is heated at 110.degree. C. for 0.5 seconds to erase the image, and a residual image density after light irradiation not greater than about 0.04 when the recording material having an image is heated at 110.degree. C. for 0.5 seconds to erase the image after light of 5,000 lux is irradiated to the recording material for 100 hours.
