ABSTRACT:
A novel optical member is disclosed. The optical member comprises a region having a distributed refractive index, wherein the region is formed from a composition used for producing an optical member comprising a polymerizable monomer and a compound represented by formula (1) (where R1, R2and R3independently denote a C1–20 alkyl group, C3–6 cycloalkyl group, halogen atom, CH2═CH—, R4—Y1— or R4—C(═Y2)Y3—, R4denotes a C1–9 alkyl group, CH2═CH— or CH2═C(CH3)—, and Y1, Y2and Y3are independently oxygen or sulfur; l and n are respectively integers of 0 to 5 and m is an integer of 0 to 4, provided that at least one of l, m and n is not 0; q, u and v are independently integers of 0 to 2) having a refractive index differing from that of the polymerizable monomer;
