(I) a first homopolymeric or copolymeric polycarbonate polyol, (ii) an organic polyisocyanate, and (iii) a hydroxy-functional (Meth) acrylate, provided that if the first polycarbonate polyol is not a copolymer, the component may further comprise [iv] a second homopolymeric or copolymeric polycarbonate polyol different from the first component, Wherein the polycarbonate polyol (s) is linked to the polyisocyanate via a urethane bond and the polyisocyanate is linked to the alkyl moiety of the (meth) acrylate via a urethane bond. |
