Patent number: RE38850Abstract: The present invention provides a functional coated product having excellent adhesion properties of a coating to a substrate, hardly causing the deterioration of the substrate and the coating due to a photocatalyst, hardly having dirt because the smoothness of the surface coating is high, and having high photocatalytic action; a method for producing the same and the use thereof. The coated product of the present invention has the first coating layer comprising a cured coating made of an acryl-modified silicone resin coating material, which is formed on the surface of the substrate, and the second coating layer comprising a cured coating made of a functional coating material containing the photocatalyst, which is formed con the surface of the first coating layer. When producing such a coated product, the acryl-modified silicone resin coating material is applied to the surface of the substrate as the first coating layer and it is semi-cured.Type: GrantFiled: December 11, 1997Date of Patent: October 25, 2005Assignee: Matsushita Electric Works, Ltd.Inventors: Junko Ikenaga, Takeyuki Yamaki, Koichi Takahama, Toshiharu Sako, Hirotsugu Kishimoto
