| titleOfInvention | New resin for optical materials |
| abstract | 【Task】 To improve the oxidation resistance of an optical material resin obtained by polymerizing and curing a novel sulfur-containing compound having an episulfide structure. [Solution] (a) a compound having at least one structure represented by the following formula (1) in one molecule: Embedded image (Wherein, R 1 represents a hydrocarbon having 1 or 2 carbon atoms, R 2 , R 3 , and R 4 each represent a hydrocarbon group having 1 to 10 carbon atoms or hydrogen. X represents S or O; The number of S is 50% or more on average with respect to the sum of S and O constituting the three-membered ring.) (B) a compound having one or more SH groups per molecule, The composition for an optical material, wherein the ratio of the total number of moles of SH groups in the compound (b) to the total number of moles of episulfide groups and / or epoxy groups in the compound (a) is 0.001 to 0.5. .
