<p>A curable composition which comprises (A) a polyfunctional polymerizable monomer such as trimechylolpropane trimethacrylate, (B) a silyl monomer such as η-methacryloyloxypropyl trimethoxysilane, (C) another radically polymerizable monomer and (D) a photochromic compound, wherein the contents of monomers (A), (B) and (C) based on the sum of them are 1 to 50 wt %, 0.5 to 20 wt %, and the balance, respectively, and wherein the photochromic compound (D) is contained in an amount of 0.0001 to 10 parts by weight relative to 100 parts by weight of the sum of monomers (A), (B) and (C); and a photochromic cured article prepared by curing the curable composition. The photochromic cured article exhibits high coloring density, fast fading and good photochromic characteristics, and is excellent in the adhesion with a hard coat applied thereon and in the handlability during mold release operation.</p> |
