Abstract:
Through an optical material composition containing a compound (a), a compound (b), a polythiol (c) and sulfur (d) according to the present invention, good mold release properties are obtained, and the occurrence of separation mark defects can be suppressed.Compound (a): a compound having the structure represented by formula (1): (In formula (1), m is an integer of 0 to 4 and n is an integer of 0 to 2.) Compound (b): a compound having the structure represented by formula (2): (In formula (2), m is an integer of 0 to 4 and n is an integer of 0 to 2.)
