FORMING METHOD OF COLORED-STATE COMPOSITION, FORMING METHOD OF COLORED IMAGE AND ERASING METHOD OF COLORED IMAGE

摘要

PURPOSE: To provide a recording method wherein in a reversible thermal recording medium for which reaction between a coloring agent and developer is used, a plurality of colored images whose achromatization initiation temperatures are different from each other are made to form on a thermal recording medium for which one kind of thermal coloring compound is used, through which a function of the recording medium is made high. ;CONSTITUTION: After a composition of a recording layer is melted and made into a colored state by applying heat to a recording body into an imagelike state by making use of a reversible thermal recording medium possessing a reversible thermal coloring composition within the recording layer, a colored image is cooled at various cooling speed and a plurality of kinds of the colored images whose achromatization initiation temperatures are different from each other are obtained, a temperature rise of the recording medium to a temperature which can eliminate the colored image having the achromatization initiation temperature on a low temperature side out of recorded images is made to perform temporarily and the recorded image whose colored image is erased is formed.;COPYRIGHT: (C)1994,JPO
