HEAT-REVERSIBLE RECORDING MATERIAL AND HEAT-REVERSIBLE RECORDING MEDIUM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a heat-reversible recording material capable of easily repeatedly forming and erasing an image under the control of a thermal energy and having a proper image contrast and a heat-reversible recording medium.;SOLUTION: The heat-reversible recording material is obtained by dispersing an electron acceptive compound and an electron donative colorational compound in a binder resin. In this case, as the electron acceptive compound, 1-(4'- hyroxyphenyl)-3-alkyl-3-octadecylurea is used. The heat-reversible recording medium comprises a heat-reversible recording layer made of the heat-reversible recording material and provided on a support.;COPYRIGHT: (C)2002,JPO
