The invention provides: a metallic coating composition and a method for forming a coating film. The metallic coating composition includes: a binder component containing a phosphate group-containing acrylic resin (A), a polyisocyanate compound (B), and a cellulose resin (C); and a vapor-deposition aluminum pigment (D), wherein the vapor-deposition aluminum pigment (D) is present in an amount of 100 to 300 parts by mass per 100 parts by mass of the total solids content of the binder component, and wherein the phosphate group-containing acrylic resin (A) is a copolymer resin of a monomer mixture consisting of 3 to 48 mass % of a phosphate group-containing polymerizable unsaturated monomer (a1), 6 to 45 mass % of a hydroxy-containing polymerizable unsaturated monomer (a2), and 10 to 91 mass % of other polymerizable unsaturated monomer (a3), based on the total amount of all of the monomers. |
