PURPOSE:To obtain the titled polymer applicable to the surface of various thermoplastic substrates because of use of water as a solvent, having excellent light resistance and safety, by polymerizing a monomer to provide water solubility with a monomer to provide photochromic properties. CONSTITUTION:The aimed polymer obtained by polymerizing at least (A) a monomer [preferably N-vinyl-2-pyrrolidone, vinyl acetate, (meth)acrylamide, N,N-dimethyl(meth)acrylamide, N,N-dimethyl-amino(meth)acrylate or (meth) acrylic acid] to provide water solubility and (B) a monomer (preferably spiropyran compound or spirooxazine compound) to provide photochromic properties.
