摘要
A monomer composition which provides a plastic optical material having high refractive index and Abbe number, a low specific gravity and excellent physical properties, such as dyeing properties, heat resistance, impact resistance and the like. The composition comprises a di(meth)acrylate compound, divinylbenzene and/or divinylbiphenyl, a crosslinking-type isocyanate compound, a polythiol compound having two or more thiol groups, and a thiourethane bonding accelerating compound. The plastic optical material obtained by the reaction of the above composition with a radical polymerization initiator is used as a material for a lens.
