A method for producing a heat-sensitive recording material comprises: preparing a first coating composition, which includes as color acceptor 4,4′-dihydroxydiphenyl sulfone, at least one sensitizer selected from the list of methylolstearamide, stearic acid amide, and dimethyl terephtalate; preparing a second coating composition, which includes: from 65 to 95% by weight of one or more (meth)acrylate from 0 to 20% by weight of photoinitiators and from 0.5 to 20% by weight of wax; applying the prepared first coating composition to form the heat-sensitive recording layer on the front side of the substrate; drying the first coating composition; applying the second coating composition to form the protective layer covering the heat-sensitive recording layer; crosslinking the protective layer covering the heat-sensitive recording layer; applying the second coating composition to form the coating on the back side of the substrate; crosslinking the coating.
