Abstract

The problem to be solved by the present invention is to provide an aqueous coating composition having an excellent finished appearance, such as smoothness and distinctness of image, as well as metallic feel and no metallic mottling when the composition comprises an effect pigment; excellent coating film performance, such as water resistance; and excellent storage stability. The present invention provides an aqueous coating composition comprising (A) acrylic resin particles, (B) a water-soluble acrylic resin, and (C) a phosphoric acid compound represented by a specific formula and having hydrocarbon (and optionally polyoxyalkylene); and also provides a method for forming a coating film, comprising applying the aqueous coating composition, as well as an article coated with the aqueous coating composition.
