Abstract
The present invention relates to a paint film embodying a new parameter representing the resistance to raindrop fouling and having very satisfactory fouling resistance, particularly resistance to raindrop fouling, even ultra-low foulability, as well as high water resistance, acid resistance, alkali resistance, and crack resistance; a coating composition capable of providing said paint film; a method for forming a satisfactory paint film using said coating composition; and an article coated with said paint film. A coating composition comprising (I) a tetramethoxysilane partial hydrolyzed condensate and at least one member selected from (A) a film-forming resin and (B) an inorganic binder containing alkoxysilyl as a reactive curing group and having a water dynamic reverse tension (Tr) of not less than 55 dyn/cm; and an antifouling paint film containing the coating composition is provided.
