PROBLEM TO BE SOLVED: To provide a photochromic composition that functions as an adhesive layer for joining optical sheets made of polycarbonate resin or the like. In particular, the present invention provides a photochromic composition capable of suppressing the solubility of the adhesive layer in the lens-forming polymerizable monomer. SOLUTION: At least one polymerizable group selected from the group consisting of a polyurethane resin (A), a (meth) acrylate group, a silanol group or a group that can be hydrolyzed to form a silanol group, an epoxy group, and a vinyl group. A photochromic composition comprising a polymerizable monomer (B) having a polymerizable monomer, a polymerizable monomer (B), and a photochromic compound (C) is provided. [Selection figure] None |
