PROBLEM TO BE SOLVED: To provide a cured photochromic product having high color-developing density, high color-fading rate and good photochromic character, excellent in hard coat adhesion and having excellent operability in releasing from the mold. SOLUTION: This cured photochromic product is obtained by polymerizing/ curing a curable composition containing (D) 0.0001-10 pt(s).wt. photochromic compound in 100 pts.wt. radical-polymerizable monomers comprising (A) a polyfunctional polymerizable monomer such as trimethylolpropane trimethacrylate, (B) a silyl monomer such asγ-methacryloyloxypropyl trimethoxysilane and (C) another radical-polymerizable monomer, wherein the content of each polymerizable monomer is 1-50 wt.% (A), 0.5-20 wt.% (B) and the balance of (C).
