    摘要： A chromene compound which develops a color of a neutral tint and has little initial coloration, high double peak characteristic and high color development sensitivity, rarely experiences the reduction of color optical density though it has high fading speed, is excellent in the durability of photochromic properties and can dissolve in a monomer composition which will become a substrate for optical articles in a high concentration, and a photochromic curable composition comprising the chromene compound and polymerizable monomers.The chromene compound is represented by the following formula (1). (wherein R3 at the 11-position is a second sulfur-containing substituent selected from the group consisting of thiol group, alkylthio group, alkoxyalkylthio group, haloalkylthio group, cycloalkylthio group, arylthio group, heteroarylthio group, sulfonyl group and sulfinyl group, R1 and R2 at the 6-position and the 7-position are a combination of an aryl group or a heteroaryl group and an electron donating group having a Hammett constant σp of −0.1 or less, or R1 and/or R2 is a first sulfur-containing substituent selected from thiol group, alkylthio group, alkoxyalkylthio group, haloalkylthio group, cycloalkylthio group, arylthio group and heteroarylthio group.).

    摘要： 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.
