Document Type and Number:
Japanese Patent JP3071130
Kind Code:
B2
Abstract:
A reversible heat-sensitive recording medium which includes at least a support and formed thereon a heat-sensitive recording layer including at least the following components: an electron-donating color-forming compound having a lactone ring, (b) an electron-accepting compound having a phenolic hydroxyl group, (c) at least one organic compound selected from compounds represented by formulae (I) to (V), and (d) a thermoplastic resin having an erasing action. The content of the thermoplastic resin having an erasing action is being from 15 to 70% by weight based on the total amount of components (a) to (d) Formulae (I) to (V) are as follows: R1-CO-N(R2)R3(I) R1-CO-NH-R4-NH-CO-R2(II) R1-CO-O-R2(III) R1-NH-CO-NH-R2(IV) R1-CO-R2(V) wherein R1 represents an alkyl group, an aryl group, an alkenyl group, or a hydroxyalkyl group; R2 and R3 each represents a hydrogen atom, an alkyl group, an aryl group, a hydroxyalkyl group, or an alkenyl group; and R4 represents an alkylene group. This reversible heat-sensitive recording medium can be easily colored and erased by means of heat energy control.
