摘要： To aim to provide a photocatalyst coating composition having a predefined photocatalytic function, which is to be formed as a coating film after being applied to a substrate and dried. The photocatalyst coating composition can improve adhesion property and abrasion resistance of the coating film. There is also provided a photocatalyst coating composition that has a shorter drying time after applied. The present invention provides a photocatalyst coating composition that is composed of a blend including: a graft copolymer of PTFE and perfluoro acid selected from the group consisting of perfluorosulfonic acid and perfluorocarbonic acid; a photocatalyst material; and at least one fluororesin selected from the group consisting of PVDF, PVF, PTFE, ETFE, PVDF-HFP, PCTFE, trifluorochloroethylene-alkyl vinyl ether copolymer, tetrafluoroethylene-alkyl vinyl ether copolymer, and trifluorochloroethylene-alkyl vinyl ether-alkyl vinyl ester copolymer.

摘要： Spherical silicone fine particles having an average particle diameter of 0.1 to 5 &mgr;m, which can be produced without decreasing a yield and also without conducting a dilution step, and a process for effectively producing the same. Spherical silicone particles are obtained by reacting an organotrialkoxysilane with a tetraalkoxysilane. Water in an amount of 20 to 150 moles is added to 1 mole of the silane mixture, which is subjected to hydrolysis under an acidic condition to obtain an aqueous or alcohol solution of an organosilanol and/or the partial hydrolyzed product thereof, and an aqueous alkaline solution is added thereto, mixed and allowed to stand to conduct polycondensation.
