Beschreibung
Zusammenfassung:	The invention relates to a heat-sensitive recording material, comprising a substrate in sheet form, having a front face and an opposing rear face; at least one heat-sensitive recording layer on at least one of the faces of the substrate in sheet form, characterised in that the heat-sensitive recording layer contains as colour acceptor a combination consisting at least of one, two, three, or more than three colour acceptor (compounds) of formula (1) in which R is an alkyl group, and at least one secondary colour acceptor containing oligomers of lactic acid according to formula (3).
