A laminated product comprising a multilayer structurencomprising an optical base and a cured polyurethanenresin layer formed thereon from a moisture-curablenpolyurethane resin and/or a precursor therefor. Thenpolyurethane resin layer is formed by applying ancoating fluid comprising a moisture-curablenpolyurethane resin and/or precursor therefor and ansolvent having a boiling point of 70 °C or higher andna solubility parameter of 8 or larger. Also providednis a coating material comprising a radical-polymerizablenmonomer ingredient, a silicone ornfluorochemical surfactant, and a photochromicncompound. In producing a photochromic optical article,nexcellent adhesion between a base and a photochromicnlayer is attained. |
