The objective of the present invention is to provide an aqueous paint composition that can form a coating with excellent smoothness, image clarity, water resistance, and chipping resistance; and that has excellent cleaning properties, as well as a method for forming a coating. As means for achieving this purpose, the present invention provides an aqueous paint composition used as an aqueous first colored paint for a multilayer coating forming method, wherein the paint composition is characterized in including (A) an aqueous film-forming resin, (B) a cross-linking agent, and (C) acrylic urethane resin composite particles. The acrylic resin of the acrylic urethane resin composite particles (C) is obtained by using, as a monomer component, 30 to 80 percent by mass of a polymeric unsaturated monomer (c-1-1) having one polymeric unsaturated group in a single molecule and having a C 4-22 alkyl group, 1 to 20 percent by mass of a polymeric unsaturated monomer (c-2) having two or more polymeric unsaturated groups in a single molecule, and 0 to 69 percent by mass of a polymeric unsaturated monomer (c-1-2) having one polymeric unsaturated group other than (c-1-1) in a single molecule. |
