Abstract
Official abstract text for this publication.
One embodiment of the present invention can provide an optical material composition that includes a cyclic compound that is represented by formula (1) and an episulfide that is represented by formula (2). Another embodiment of the present invention can provide an optical material production method that includes a step wherein, with respect to the total amount of the optical material composition, 0.0001-10 mass % of a polymerization catalyst is added to the optical material composition and the optical material composition is polymerization cured. (In formula (2), m is an integer from 0 to 4, and n is an integer from 0 to 2.)
First claim
Opening claim text (preview).
The invention claimed is: 1. A cyclic compound represented by Formula (1) below: 2. A composition for optical material comprising the cyclic compound represented by Formula (1) according to claim 1 and an episulfide compound represented by Formula (2) below: wherein m represents an integer of 0-4 and n represents an integer of 0-2. 3. The composition for optical material according to claim 2 , wherein the amount of the cyclic compound represented by Formula (1) above is 0.001-5.0% by mass. 4. The composition for optical material according to claim 2 , further comprising polythiol. 5. The composition for optical material according to claim 2 , further comprising sulfur. 6. The composition for optical material according to claim 4 , further comprising polyisocyanate. 7. A polymerizable and curable composition comprising the composition for optical material according to claim 2 and a polymerization catalyst in the amount of 0.0001% by mass to 10% by mass with respect to the total amount of the composition for optical material. 8. An optical material obtained by curing the composition for optical material according to claim 2 . 9. An optical lens comprising the optical material according to claim 8 . 10. A method for producing an optical material, comprising the steps of: adding a polymerization catalyst in the amount of 0.0001% by mass to 10% by mass with respect to the total amount of the composition for optical material according to claim 2 ; and polymerizing and curing the resultant. 11. The method for producing an optical material according to claim 10 , further comprising a step of allowing partial polymerization of the episulfide compound represented by Formula (2) and sulfur, prior to the polymerizing and curing step. 12. An optical material obtained by curing the polymerizable and curable composition according to claim 7 . 13. An optical lens comprising the optical material according to claim 12 .
