Abstract (en)
[origin: EP2033801A1] A heat-sensitive recording material has a heat-sensitive recording layer containing a dye precursor and a dye acceptor, provided on one or both sides of a substrate. The dye precursor and the dye acceptor react in presence of heat to form a dye. The heat-sensitive recording layer contains N-(p-toluene sulfonyl)-N'-3-(p-toluene sulfonyl-oxy-phenyl)-urea as the dye acceptor and 2-(2H-benzotriazol-2-yl)-p-cresol as sensitizer.
