<p>A photochromic curable composition prepared by blending a monomer mixture comprising: (A) a compound having at least one epoxy group in the molecule (e.g., glycidyl methacrylate), (B) polypropylene glycol di(meth)acrylate, (C) polyethylene glycol di(meth)acrylate, and (D) a (meth)acrylate monomer and/or a styrelic monomer with (E) α-methylstyrene dimer and (F) a photochromic compound. This composition is excellent in moldability in curing and can give a product of curing excellent in the persistence of photochromism.</p> |
