The present invention provides an aqueous coating composition for use as an aqueous first colored coating composition in a multilayer coating-forming method, the coating composition containing an aqueous film-forming resin (A), a crosslinking agent (B), and acrylic urethane resin composite particles (C). The acrylic resin of the acrylic urethane resin composite particles (C) is obtained by using, as constituent monomers, 30 to 80 mass % of a polymerizable unsaturated monomer (c-1-1) having one polymerizable unsaturated group per molecule and having a C 4-22 alkyl group, 1 to 20 mass % of a polymerizable unsaturated monomer (c-2) having two or more polymerizable unsaturated groups per molecule, and 0 to 69 mass % of a polymerizable unsaturated monomer (c-1-2) having one polymerizable unsaturated group per molecule and being other than the polymerizable unsaturated monomer (c-1-1). |
