ABSTRACT:
There are provided a resin composition, which has optical properties such as a high refractive index, has excellent restorability and scratch resistance, and has good adhesion to a substrate, and, when utilized as an optical member (lens) used, for example, in screens for projection televisions or the like, can satisfy various property requirements, and a cured product of the resin composition. The resin composition comprises: an epoxy (meth)acrylate oligomer having an average molecular weight of not more than 1500, a copolymer of a (meth)acrylic ester with styrene or α-methylstyrene, a thermoplastic urethane elastomer, a (meth)acrylic ester monomer, and a photopolymerization initiator.
