Non-aqueous composition and heat-sensitive recording material

A heat-sensitive recording medium is presented, comprising a substrate (2) with a first side and a second side remote therefrom a heat-sensitive recording layer (4) which is placed on the first side of the substrate (2) and comprises at least one colorant precursor and colour acceptor, the colorant precursor and colour acceptor reacting with one another under the influence of heat to form a colour, a printed protective layer (9) which covers the recording layer (4), is crosslinkable and crosslinked under the influence of energy-rich radiation and is based on (meth)acrylates, characterised in that the protective layer (9) contains from 65 to 95% by weight of one or more (meth)acrylates, selected from the group comprising polyether(meth)acrylate, epoxy(meth)acrylate and urethane(meth)acrylate from 0 to 20% by weight of photoinitiators and from 0.5 to 20% by weight of wax, at least one (meth)acrylate from the aforementioned group being an amine-modified (meth)acrylate and the percentages by weight adding up to form from 65.5 to 100% by weight of the layer (9), the protective layer (9) is printed on from a non-aqueous phase, at least one pigmented print layer (5,6) is applied between the recording layer (4) and the protective layer (9) and/or, in the case of a multi-ply protective layer (9), between the at least two plies of the protective layer (9).
