The invention relates to a coating composition for producing a heat-sensitive recording material or heat-sensitive recording layer, comprising one or more dye precursors and one or more colour developers based on lactic acid units, as well as a coating colour for producing a coating composition or a heat-sensitive recording layer, comprising one or more dye precursors and one or more colour developers based on lactic acid units, as well as a heat-sensitive recording material comprising a carrier substrate and a heat-sensitive recording layer according to the invention, and a method for producing this heat-sensitive recording material and the use of this heat-sensitive recording material. The invention also relates to a coating composition or heat-sensitive recording layer of this type, which also contains at least one further colour developer that is not based on lactic acid units. The invention further relates to a compound based on lactic acid units, preferably for use as a colour developer in the above-mentioned context, as well as a use itself and a method for producing this compound based on lactic acid units.
