Abstract (en)
[origin: EP2033800A1] The thermosensitive recording material comprises a substrate, color former and two color acceptors containing heat sensitive recording layer. A pigmented intermediate layer is formed between the substrate and the heat sensitive recording layer. The color acceptors are N-(p-toluenesulfonyl)-N'-(3-p- toluenesulfonyl-oxy-phenyl)urea and a urea-urethane compound, where the wt.% proportion of the N-(p-toluenesulfonyl)-N'-(3-p- toluenesulfonyl-oxy-phenyl)urea and the urea-urethane compound is 10:1-1:1.
