    Abstract: A colored base coating composition includes a chlorinated polyolefin resin grafted with an acrylic component in which the acrylic component has a glass transition temperature (Tg) of 60° C. or more and an OH group-containing acrylic resin. The chlorinated polyolefin resin grafted with the acrylic component and the OH group-containing acrylic resin have a mass ratio of nonvolatile matters thereof ranging from 70/30 to 50/50. The colored base coating composition is applied on a substrate made of a nonpolar resin to form a colored base coat, and the coat is dried so that a nonvolatile matter of the coat becomes 70 to 100% by mass. A clear coating composition having a coating viscosity of 15 to 50 mPa·s is applied on the colored base coat to form the clear coat, and the clear coat is irradiated with an active energy ray in an atmosphere having an oxygen content of 5% by mass or less to be cured.

  • Publication number: 20060159948
    Abstract: After a silicatizing flame, a titanium oxidizing flame, or an aluminum oxidizing flame is blown together with an oxidizing flame onto the surface of a resin base material to perform surface modification treatment, dry plating or wet plating is performed on the surface of the resin base material to thereby form a plating film.

  • Publication number: 20030108751
    Abstract: In the silver mirror pre-treating step, a tin[II] chloride solution with tin[II] actually serving as a co-catalyst is used for supporting tin[II] on the surface of the basecoat layer in the co-catalyst-supporting step. In the next washing step, the surface of the basecoat layer is washed with water. In the still next catalyst-supporting step, a palladium chloride solution with palladium[II] actually serving as a catalyst is used for supporting palladium[II] on the surface of the basecoat layer. After that, the resulting laminate is washed in the next washing step and then plated through silver mirror reaction in the still next plate layer-forming step.
