摘要： Plastic lenses for spectacles having a high refractive index and a high Abbe's number, and having good transparency, heat resistance, mechanical strength and impact resistance are produced. Plastic lenses for spectacles are produced through polymerization of an epithio group-having compound (a), a polythiol compound (b) and a polyisocyanate compound (c) whereby the ratio (by mol) of the polythiol compound (b) to the polyisocyanate compound (c) is at least 1.2 calculated on the basis of —SH and —NCO groups. The invention also provides a process for preparing such lenses and a catalyst for use in said process.
