摘要

Polyurethane compositions comprising a writing monomer component a) containing at least 10% by weight based on the total composition of one or more unsaturated urethanes a) of formulas (I) to (III) as writing monomers and corresponding polymeric compounds or matrix precursors as matrix for the writing monomers in which R is, independently from each other, respectively a radiation curable group and X is, independently from each other, respectively a single bond between R and C = O or a linear, branched or cyclic hydrocarbon moiety that, if appropriate, contains heteroatoms and / or that is substituted with functional groups.
