Color acceptor reacting in a color-forming manner to a pigment precursor and heat-sensitive recording material having such a color acceptor

摘要

A color acceptor for chemical reaction with a dye precursor to form a visually recognizable color. The color acceptor is constructed of lactic acid monomers. Also disclosed is a heat-sensitive recording material with a substrate and a heat-sensitive recording layer, wherein the heat-sensitive recording layer contains at least one dye precursor and at least one color acceptor which react with one another in a color-forming manner when heat is applied, and wherein the color acceptor is constructed of lactic acid monomers.
