PHOTOCHROMIC COMPOSITION AND OPTICAL ARTICLE USING PHOTOCHROMIC COMPOSITION |
摘要 |
To provide a photochromic composition which functions as an adhesive layer for bonding two optical sheets that are formed of a polycarbonate resin or the like, so that a laminate that is obtained by bonding two optical sheets with the composition being sandwiched therebetween has excellent adhesion, heat resistance and photochromic properties. In particular, to provide a photochromic composition which is capable of forming an adhesive layer that is not decreased in the adhesion between the optical sheets even in cases where the adhesive layer is in contact with hot water. Provided is a photochromic composition which contains a urethane polymer having a polymerizable group (component A) and a photochromic compound (component B). |
