PROBLEM TO BE SOLVED: To provide a photochromic composition which can function as an adhesive layer for bonding optical sheets made from a polycarbonate resin or the like and which can yield a laminate that exhibits excellent tight adhesion, heat resistance and photochromic properties, and to especially provide a photochromic composition that can form an adhesive layer that does not decrease the adhesion between optical sheets even if contacting with hot water.SOLUTION: The photochromic composition includes: a non-reactive polyurethane resin (component A); an isocyanate compound (component B); and a photochromic compound (component C). |
