Abstract

Polymerizable compositions capable of giving transparent resin having a high refractive index of at least 1.57 which are useful as optical materials and glass adhesives are disclosed. The compositions comprise a mono(meth)acrylate having a biphenyl skeleton and a di(meth)acrylate having a biphenyl skeleton or a bisphenol skeleton. The compositions cure rapidly, particularly under irradiation of ultraviolet light.
