NOVELTY - A coating composition comprises aqueous medium, hydrophobic resin particles (1) dispersed in the aqueous medium, hydrophilic inorganic fine particles (2), and oxidizing agent (6) containing peroxide, perchloric acid, chlorate, persulfuric acid, perphosphoric acid, and/or periodate.    USE - Coating composition is used for electric equipment e.g. ventilation fan, air conditioner (all claimed), elevator, refrigerator, and solar cell.    ADVANTAGE - The electric equipment using coating composition has excellent antifouling property and adhesiveness.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) coating method. A primary solution is obtained by dispersing hydrophilic inorganic fine particles and hydrophobic resin particles in aqueous medium. The oxidizing agent is added to the obtained primary solution to obtain secondary solution. The obtained secondary solution is coated on a to-be-coated component (5), and dried. Thus, coating method is carried out;    (2) air conditioner, which has an intake port capable of absorbing gas, heat exchanger, fan capable of circulating gas which is heat-exchanged by the heat exchanger, air-path formation component capable of forming path of gas carried with fan, vane, flap, and cover having heat exchanger and fan. At least one portion of heat exchanger, fan, vane, flap, air-path formation component, and cover is coated with a coating film (4) containing coating composition. The coating film has an adhesion reinforcing layer;    (3) ventilating fan, which has a housing having inlet port, vane component arranged at the path of gas taken in from the inlet port, motor capable of rotating vane component, and exhaust port capable of exhausting gas by gas flow formed by vane component rotated by motor. At least one portion of inlet port, vane component, motor, exhaust port, and housing is covered with the coating film comprising coating composition; and    (4) electric equipment, which has coating film containing coating composition.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the coating film containing coating composition.
