Patent ID: 7576143

Claim:
A polyurethane acrylate (A), comprising: as synthesis components (a) at least one polyisocyanate which comprises isocyanurate groups, based on 1-isocyanato-3,3,5-trimethyl-5-(isocyanatomethyl)cyclohexane, (b) at least one polyisocyanate which comprises isocyanurate groups, based on hexamethylene diisocyanate, (c) at least one aliphatic and/or cycloaliphatic diisocyanate, (d1) at least one polyetherdiol or polyesterdiol having a molecular weight of from 500 to 2000, (d2) optionally, at least one diol having a molecular weight of less than 220 g/mol, e) at least one compound having at least one group reactive toward isocyanate and at least one unsaturated group capable of free radical polymerization, and f) optionally, at least one compound having exactly one group reactive toward isocyanate.
