Patent ID: 8592514

Claim:
A urethane (meth)acrylate resin composition comprising: a urethane (meth)acrylate resin (A), a polymerizable unsaturated monomer (B), a paraffin wax (C), and an ethylene-α-olefin co-oligomer (D), wherein a mass ratio of the paraffin wax (C) to the ethylene-α-olefin co-oligomer (D) is 0.05 to 50, wherein an amount of the paraffin wax (C) added is 500 to 10,000 ppm relative to 100 parts by mass in total of the urethane (meth)acrylate resin (A) and the polymerizable unsaturated monomer (B), wherein an amount of the ethylene-α-olefin co-oligomer (D) is 0.01 to 2 parts by mass relative to 100 parts by mass in total of the urethane (meth)acrylate resin (A) and the polymerizable unsaturated monomer (B), and wherein a mixing ratio (mass %) of the urethane (meth)acrylate resin (A) and the polymerizable unsaturated monomer (B) is (A)/(B)=30/70 to 70/30, wherein a number-average molecular weight of the ethylene-α-olefin co-oligomer (D) is 500 to 2,500.
