Abstract

A composition includes: (a) 10-90 mass-percent of an organopolysiloxane resin; (b) 10-90 mass-percent of a (meth)acrylate component consisting of: (i) at least one monofunctional (meth)acrylate that contains an ether group and/or a hydroxyl group; and optionally (ii) at least one monofunctional (meth)acrylate containing alkyl groups and that is free of ether and hydroxyl groups; where the molar ratio of (ii) to (i) is in a range of 0:1 to 22:1 and wherein when the (meth)acrylate component comprises a monofunctional (meth)acrylate that contains a hydroxyl group then it also comprises as part of component (i) at least one of a monofunctional (meth)acrylate that contains an ether group and/or component (ii) a monofunctional (meth)acrylate containing alkyl groups and that is free of ether and hydroxyl groups; (c) 0.11-11 mass-percent of a crosslinker; and (d) 0.1-10 mass-percent of a photoradical initiator; where mass-percentages are relative to the combined mass of components (a)-(c).
