摘要：
A laminated product comprising a multilayer structure comprising an optical base and a cured polyurethane resin layer formed thereon from a moisture-curable polyurethane resin and/or a precursor therefor. The polyurethane resin layer is formed by applying a coating fluid comprising a moisture-curable polyurethane resin and/or precursor therefor and a solvent having a boiling point of 70 °C or higher and a solubility parameter of 8 or larger. Also provided is a coating material comprising a radical-polymerizable monomer ingredient, a silicone or fluorochemical surfactant, and a photochromic compound. In producing a photochromic optical article, excellent adhesion between a base and a photochromic layer is attained.
