Composition for optical material |
| abstract |
The present invention pertains to a composition for an optical material, wherein the occurrence of polymerization unevenness called striae has been suppressed, particularly striae that occur in high-powered lenses with sharp curves. Specifically, the composition for an optical material includes: a polymerization catalyst with a mass ratio between dibutyltin dichloride and monobutyltin trichloride of 97.0/3.0-100.0/0.0; a polythiol compound; and a polyiso(thio)cyanate compound. |
