    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.

    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 layer further includes an erasure promoter including one or more secondary amide group having the following formulas (1), (2) or (3): wherein each of R1, R2, R3, R4 and R5 independently represents a hydrocarbon group which is optionally substituted and which may be saturated or unsaturated, and wherein R1 and R2 are optionally combined to form a ring which may include one or more of a nitrogen atom, an oxygen atom and a sulfur atom. Alternatively, the erasure promoter may include two or more secondary amide groups having formula (1), (2) or (3).
