Patent number: 8012588Abstract: A laminated product has 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.Type: GrantFiled: February 13, 2004Date of Patent: September 6, 2011Assignee: Tokuyama CorporationInventors: Shinobu Izumi, Junji Momoda
