摘要:
A photochromic composition functions as an adhesive layer for bonding optical sheets or films made from a polycarbonate resin or the like, and can be used to produce a laminated sheet that exhibits excellent adhesive properties, heat resistance, photochromic properties, and perspiration resistance. The photochromic composition includes (A) a polyurethane-urea resin having a urea bond in a molecular chain, in which a tetrahydrofuran insoluble content is 20.0 to 90.0 wt %; and (B) a photochromic compound.
