| 摘要 |
This polymerizable composition for photochromic optical material includes: a polymerizable monomer (A) having at least two ethylenically unsaturated groups; an ethylenically unsaturated polymerizable monomer (B) having one (meth) acrylic group and an aromatic ring; a polythiol (C) having at least three mercapto groups; and a photochromic compound (D). The number of moles of mercapto groups included in the polythiol (C) is no more than 0.3 times the total number of moles of ethylenically unsaturated groups included in the polymerizable monomer (A) and the polymerizable monomer (B). |
