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 oligomer component comprising urethane (meth)acrylate, produced by reacting a bisphenol A polyalkoxydiol, an organic diisocyanate and a hydroxyl-containing mono(meth)acrylate, and a bisphenol A epoxy (meth) acrylate; a monomer component comprising a phenoxy polyethylene glycol (meth)acrylate and a bisphenol A polyethoxydiol di(meth)acrylate; and a photopolymerization initiator. The resin composition has a refractive index of not less than 1.55 after resin curing.
