| titleOfInvention |
Process for producing a novel resin for optical materials having excellent color tone and transparency |
| abstract |
A process for producing a resin used for optical materials which process comprises curing a composition comprising an ultraviolet light absorbent and an epithio compound by polymerization in the presence of a catalyst, wherein amounts of the ultraviolet light absorbent and the catalyst each expressed as parts by weight per 100 parts by weight of the total amount of the epithio compound, the ultraviolet light absorbent and the catalyst satisfy both of the following relations (a) and (b): <MATH> Coloration and clouding of the material of a lens obtained by polymerization of an epithio compound caused by addition of an ultraviolet light absorbent can be prevented. |
