Abstract: A layered 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.

Abstract: Novel fulgimide compounds substituted on the nitrogen atom constituting the imide ring with a phenyl group having an electron attractive group at least at one of the m-positions, which are represented by general formula (I), wherein the group of general formula (a) is an optionally substituted divalent aromatic hydrocarbon or unsaturated heterocyclic group; the group of general formula (b) is an optionally substituted norbornylidene, bicyclo[3.3.1]nonylidene or adamantylidene group; and R is an electron attractive group; and the use of them as photochromic material. The fulgimide compounds develop colors in higher densities than those of the photochromic compounds of the prior art.

Abstract: An ultraviolet absorber, e.g., 2,2'-dihydroxy-4,4'-dimethoxybenzophenone, is added to and mixed with an allyl monomer and the monomer is then polymerized using a peroxyester polymerization initiator. Alternatively, the acid value of an allyl monomer is reduced and this monomer is then polymerized using an ultraviolet absorber and a peroxydicarbonate polymerization initiator. Thus, a plastic lens is obtained. The plastic lens obtained has a low transmittance of ultraviolet rays, which exert various adverse influences on the human body, and has a low yellowness.
