Patent ID: 7169845

Claim:
A composition for resin comprising an episulfide compound having, in one molecule, at least one epithio structure represented by the following Formula 2: wherein R 5 is C1–C10 hydrocarbylene or single bond, R 6 , R 7 and R 8 are each independently C1–C10 hydrocarbyl or hydrogen, Y is O, S, Se or Te, p is an integer from 1 to 5, and q is an integer from 0 to 5, and at least one halide of a 13–16 group element of the long periodic table as a stabilizer for the episulfide compound, wherein the halide is represented by the following Formula 5: R 17 s MX 2 t (5) wherein R 17 is C1–C8 alkyl, C1–C4 alkoxyl or phenyl; M is silicon, germanium, tin or antimony; X 2 is halogen, halogenated alkyl, halogenated alkenyl, halogenated alkoxyl, or halogenated aryl; s is an integer including zero; t is an integer of 1 or more, with s+t being equal to the valency of M; and when s is an integer of two or more, a plurality of R 17 groups may be the same or different.
