| 发明名称 | Radical polymerizable composition, cured product, and plastic lens | ||
| 摘要 | There are provided a radical polymerizable composition having a low viscosity suitable for coating, a cured product obtained by curing the composition, the cured product having a high refractive index and high toughness and being not easily cracked or chipped when cutting, and a plastic lens obtained by curing the composition. A radical polymerizable composition includes phenylbenzyl(meth)acrylate (A), a urethane(meth)acrylate (X) having an aromatic ring in its molecular structure, and a radical polymerization initiator (Y) as essential components. | ||

| 主权项 | 1. A radical polymerizable composition comprising: phenylbenzyl(meth)acrylate (A), a urethane(meth)acrylate (X) having an aromatic ring in its molecular structure, a radical polymerization initiator (Y), and bis[(meth)acryloylmethyl]biphenyl (B) or a biphenyl compound (C) having a molecular structure in which biphenyl structures are bonded to each other only through a methylene as essential components. | ||
