Abstract (en)
[origin: EP2112000A1] Heat-sensitive recording material comprises a substrate comprising a heat-sensitive recording layer on at least one side, where: the heat-sensitive recording layer contains an isocyanate components, and a leuco dye system comprising dye precursor and a dye acceptor reacting with each other under the influence of heat to form a dye; the dye acceptor comprises at least N-(para-toluenesulfonyl)-N'-3-(para-toluenesulfonyl-oxyphenyl) urea; and the heat-sensitive recording layer comprises an imino component that forms an anti-fade system together with the isocyanate components.
