Abstract:
The present invention makes it possible to provide a compound represented by formula (1) and a composition for an optical material containing this compound.
(Where m+n=4, m represents an integer of from 0 to 3, and n represents an integer of from 1 to 4.) In addition, the present invention makes it possible to provide a method for producing an optical material, the method including a step for adding 0.0001-10 parts by mass of a polymerization catalyst per 100 parts by mass of the composition for an optical material, polymerizing, and curing.
