Abstract

A proposed heat-sensitive recording material comprises a substrate, a heat-sensitive recording layer containing color formers and color acceptors, and a protective layer covering this heat-sensitive recording layer. The heat-sensitive recording layer has, as color acceptor, at least 66⅔ percent by weight of 4,4′-dihydroxydiphenyl sulfone based on the total percentage of color acceptors in the heat-sensitive recording layer, and the protective layer has, as binder, at least 60 percent by weight of diacetone-modified polyvinyl alcohol based on the total percentage of binder in the protective layer.
