Abstract

There are provided a radical polymerizable composition having a low viscosity suitable for coating and a cured product and a plastic lens each obtained by curing the composition, the cured product having a high refractive index, good adhesiveness to a plastic film substrate, and good adhesiveness kept even under high-temperature and high-humidity conditions. The radical polymerizable composition includes phenylbenzyl (meth)acrylate (A), an epoxy (meth)acrylate (X) having an aromatic ring in its molecular structure, and a radical polymerization initiator (Y) as essential components.
