Abstract (en)
[origin: WO2019149806A1] The invention relates to a heat-sensitive recording material comprising a substrate, a heat-sensitive recording layer which comprises N-(4-methylphenylsulfonyl)-N'-(3-(4-methylphenylsulfonyloxy)phenyl)urea and/or N-[2-(3-phenylureido)phenyl]benzol sulfonamide, and an intermediate layer which is arranged between the substrate and the heat-sensitive recording layer and which comprises calcined aluminum silicate. The invention also relates to a method for producing a heat-sensitive recording material and to the use of calcined aluminum silicate in an intermediate layer of a heat-sensitive recording material.
