| titleOfInvention | Composition for optical materials |
| abstract | To suppress the opacity of a cured product obtained by polymerizing and curing a composition containing sulfur and an episulfide compound, particularly to suppress the occurrence of opacity in a lens having a thick center thickness called a plus diopside lens, It is an object of the present invention to provide a composition for an optical material capable of predicting the presence or absence of occurrence of clouding after curing and judging whether a clouding occurs or not. And a composition for an optical material characterized by containing sulfur and an episulfide compound having a turbidity value of not more than 10 ppm as a 30 mass% disulfuric carbon solution. That is, in an optical material produced from a composition for an optical material containing sulfur and an episulfide compound satisfying the above-described conditions for the turbidity value, cloudiness is prevented and good transparency is realized. It is possible to provide a composition for an optical material capable of judging the presence or absence of occurrence of clouding after curing in the step before polymerization polymerization and judging the presence or absence of occurrence of clouding. |
