摘要：
A photocurable resin composition including: (A) a urethane (meth)acrylate oligomer having a polyoxyalkylene structure, (B) a (meth)acrylic polymer, (C) a (meth)acrylic monomer, and (D) a photopolymerization initiator, wherein the component (A) is produced using monomer components including (a1) a polyoxyalkylene polyol, (a2) a polyisocyanate, and (a3) a hydroxyl group-containing mono(meth)acrylate compound, a relationship N (=n1/n2) between the total mass n1 of the monomer components and the total equivalent weight n2 of acryloyl groups within the all monomer components is 4,000 or greater, and the component (A) is substantially free of unreacted isocyanate groups.
