摘要:
A polymerizable composition for photochromic optical materials of the present invention includes a polymerizable monomer (A) having two or more ethylene-based unsaturated groups, an ethylene-based unsaturated polymerizable monomer (B) having one (meth)acrylic group and an aromatic ring, a polythiol (C) having three or more mercapto groups, and a photochromic compound (D), and the molar number of the mercapto groups included in the polythiol (C) is not more than 0.3 times with respect to the total molar number of the ethylene-based unsaturated groups included in the polymerizable monomer (A) and the polymerizable monomer (B).
