PROBLEM TO BE SOLVED: To provide a photocurable resin composition for an optical disk protector which has softness with controlled surface tack after being photocured and is used for protecting an optical disk surface from scratch.SOLUTION: The photocurable resin composition for an optical disk protector contains a photoradically polymerizable oligomer (component A) and a photoradical polymerization initiator (component B). The component A is at least one compound selected from a diene oligomer, a urethane oligomer and a (meth)acrylate oligomer, the (meth)acrylate oligomer is at least one compound selected from the group consisting of an epoxy acrylate oligomer, a polyether (meth)acrylate oligomer, a polyester (meth)acrylate oligomer and an acrylic acrylate oligomer, and the component A has a molecular weight of 500-100,000. The component B is a monomer and/or an oligomer of 2-hydroxy-2-methyl-1-[4-(1-methylvinyl)phenyl]propanone. |
