Abstract:
1. A curable composition comprising: a) 50 to 99 parts by weight of a (meth)acryloyl oligomer having a plurality of pendent, free-radically polymerizable functional groups and a T b) 1 to 50 parts by weight of a free-radically polymerizable crosslinking agent and/or a diluent monomer, and c) 0.001 to 5 parts by weight of a photoinitiator, based on 100 parts by weight of a) and b) wherein said oligomer comprises of polymerized monomer units comprising: a. 50 to 99 parts by weight of (meth)acrylate esters monomer units homopolymerizable to a polymer having a glass transition temperature ≧20° C., b. 1 to 50 parts by weight of monomer units having a pendent, free-radically polymerizable functional group; c. less than 40 parts by weight of monomer units homopolymerizable to a polymer having a glass transition temperature <20° C., based on 100 parts by weight of a) and b).
