Abstract:
1. A photocurable coating composition, comprising: (a) about 70 to about 99 parts by weight of a (meth)acryloyl monomer; (b) about 1 to about 30 parts by weight of a (meth)acryloyl oligomer; (c) about 1 to about 99 parts by weight of a mixture of an organic solvent and a diluted monomer which include low viscosity monomer based on 100 parts by weight of the overall (a) and (b) contained within the photocurable coating composition; (d) about 0.001 to about 5 parts by weight of a photo-initiator based on 100 parts by weight of (a), (b) and (c); and (e) about 1 to about 10 parts by weight of a free-radically polymerizable cross-linking agent based on 100 parts by weight of the photocurable coating composition, wherein the (meth)acryloyl oligomer comprises a polymerized monomer unit that comprises: (a) about 50 to about 99 parts by weight of a (meth)acryloyl monomer unit that is homo-polymerizable to a polymer having a Tg of not less than about 10° C.; (b) about 1 to about 50 parts by weight of a monomer unit having a pendent, free-radically polymerizable functional group; and (c) more than 0 parts by weight and less than about 40 parts by weight of a monomer unit that is homo-polymerizable to a polymer having a Tg of less than about 40° C., based on 100 parts by weight of (a) and (b).
