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.

Thermosensitive recording material

A heat-sensitive recording material includes a paper web with recycled fibers and a heat-sensitive recording layer includes color formers and color acceptors. The amount of recycled fiber contained in the paper web is at least 70 percent by weight, and the heat-sensitive recording layer has, as color acceptor, at least 33&#x2153; percent by weight of N-(p-toluenesulphonyl)-N'-3-(p-toluenesulphonyloxyphenyl)urea in relation to the total content of color acceptors in the heat-sensitive recording layer.

A heat-sensitive recording material is proposed, which comprises a substrate and a heat-sensitive recording layer that contains color formers and color acceptors, where and a urea-urethane compound with the following formula (2):
