  • Publication number: 20120142238
    Abstract: Provided is a photocatalytic coating in which the coating per se is hardly eroded even when a photocatalyst is excited and a coating surface having strong hydrophobic tendency can be formed. The photocatalytic coating is prepared by dispersing or dissolving at least a photocatalyst, a tetrafluoro-ethylene-based resin obtained by graft polymerization of a sulfonic acid, a compound containing metal ion having an ionic radius not less than an ionic radius of calcium and/or complex ion having an ionic radius not less than the ionic radius of calcium into a solvent. Further, hydroxide is used as the compound containing the metal ion or an electrically neutral surfactant is added to the photocatalytic coating.

  • Patent number: 7323251
    Abstract: The present invention provides a decorative sheet having a base film made of a thermoplastic polyester resin and a decorative layer on the base film, and provides a decorated resin molding produced by using the decorative sheet. The base film is not broken in both of MD (a flow direction of film-forming) and TD (a direction perpendicular to MD) and has a stress of 20 N/cm2 or less in any of MD and TD under a 200% elongation at 80° C. The decorated resin molding includes a resin molding and the decorative sheet which is unitedly laminated to the resin molding. The decorative layer of the decorative sheet faces toward the resin molding. The decorative sheet is suitable for producing the decorated resin molding by a decorating injection molding method.
