Abstract
PURPOSE: To produce title recording material having excellent storage stability, which provides clear-colored pictures, by using low temperature- and high temperature-sensitive color-developing layers which develop into different colors and in which the low temperature-sensitive color-developing layer contains a specific ester compound, and a decolorization layer is placed between the layers.
CONSTITUTION: In a multicolored heat-sensitive recording material prepared by placing a high temperature-sensitive color-developing layer (as the color-developing component, for example, 3-diethylamino-6-methyl-7-chlorofluoran is used) and a low temperature-sensitive color-developing layer containing as the color-developing components, a colorless (pale colored) leuco dye and a phenolic substance (or acidic substance) on a support in this order; as a decolorizing agent, a polyhydric alcohol fatty acid ester having an HLB (hydrophilic lipophilic balance) of not greater than 5, such as sorbitan tristearate is added to the low temperature heat- sensitive color-developing layer, and a decolorization layer containing a decolorizing agent for the color-developing components used in the low temperature heat-sensitive color-developing layer, such as an alkylene oxide/bisphenol adduct is placed between the two layers.
