摘要：
Provided is a photochromic composition which can function as an adhesive layer for bonding optical sheets made from a polycarbonate resin or the like and a laminated article using said composition exhibits excellent tight adhesion, heat resistance and photochromic properties. In particular, provided is a photochromic composition which can prevent an elution of the composition from the optical sheets when embedding and polymerizing in a polymerizable monomer. The photochromic composition comprises a polyurethane resin (A) having an isocyanurate structure and a photochromic compound (B).
