Abstract:
1. A radiation-curable base resin composition comprising: a multifunctional urethane(meth)acrylate having three or more functional groups at 3 to 35 parts by weight; a bifunctional urethane(meth)acrylate at 3 to 35 parts by weight; at least one (meth)acrylic acid ester monomer selected from the group consisting of a monofunctional (meth)acrylic acid ester monomer and a multifunctional (meth)acrylic acid ester monomer at 20 to 60 parts by weight; and a radiation polymerization initiator at 0.1 to 15 parts by weight, wherein the multifunctional urethane (meth)acrylate having three or more functional groups is a mixture of a trifunctional urethane (meth)acrylate and a hexafunctional urethane (meth)acrylate, wherein the trifunctional urethane (meth)acrylate and the hexafunctional urethane (meth)acrylate are mixed at a weight ratio of 1:1 to 4:1, wherein the (meth)acrylic acid ester monomer is a mixture of a monofunctional (meth)acrylic acid ester monomer and a multifunctional (meth)acrylic acid ester monomer, and wherein the monofunctional (meth)acrylic acid ester monomer is present at a content of 50 to 90 parts by weight, and the multifunctional (meth)acrylic acid ester monomer is present at a content of 20 to 60 parts by weight, based on 100 parts by weight of the total (meth)acrylic acid ester monomer.
