Patent ID: 7846871

Claim:
Heat-sensitive recording medium comprising: a substrate with a first side and a second side remote therefrom a heat-sensitive recording layer which is placed on the first side of the substrate 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-on protective layer which covers the recording layer, is crosslinkable and crosslinked under the influence of energy-rich radiation and is based on (meth)acrylates, the protective layer 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, the protective layer is printed on from a non-aqueous phase, at least one pigmented print layer is applied between the recording layer and the protective layer or, in the case of a multi-ply protective layer, between the at least two plies of the protective layer, and the protective layer comprises at least a first application plane facing the recording layer and a second application plane turned away from the recording layer and at least partially overlapping the first application plane.
