Abstract (en)
[origin: WO2019149805A1] The invention relates to a coating composition for producing a heat-sensitive recording material and to a corresponding heat-sensitive recording layer. The coating composition comprises one or more color developers, one or more dye precursors, one or more specific fatty acid amides, and one or more (additional) specific sensitizers. The invention also relates to a heat-sensitive recording material comprising a carrier substrate and a heat-sensitive recording layer according to the invention, to the use of specific fatty acid amides in order to increase the grease resistance of a heat-sensitive recording material or a heat-sensitive recording layer, and to a method for producing a heat-sensitive recording material or a heat-sensitive recording layer according to the invention.
