A heat-sensitive recording material including a web-shaped substrate having a front side and an opposite reverse side, and at least one heat-sensitive recording layer on either or both of the sides of the web-shaped substrate. The heat-sensitive recording layer contains at least one dye precursor at least one salicylic acid derivative as a (color) developer reactive with this at least one dye precursor, and polyvinylpyrrolidone as auxiliary component augmenting the (color) developer the at least one salicylic acid derivative is 3,5-di(&#x3b1;-methylbenzyl)salicylic acid.

Heat-sensitive recording material having a novel color acceptor combination

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 66&#x2154; 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.
