Abstract:
1. A method for forming a shining coating film, comprising the steps of: coating a shining material-containing solvent type first base coat coating onto a base material to form a first base coating film; coating a shining material-containing solvent type second base coat coating onto the first base coating film to form a second base coating film; coating a top clear coating onto the second base coating film to form a clear coating film; and then baking a formed multilayered coating film at the same time; wherein: the first base coat coating contains a polyester-polycarboxylic acid in a ratio of 50 to 95 mass % in terms of nonvolatile concentration based on a total resin nonvolatile concentration, wherein the total resin nonvolatile concentration relating to the first base coat coating is the total concentration of the nonvolatiles of the polyester-polycarboxylic acid and other resins in the first base coat coating, and wherein the first base coat coating has a nonvolatile concentration of 50 to 65 mass % when coated, and the first base coat coating is a coating such that the first base coating film will have a nonvolatile concentration of not less than 75 mass % when the second base coat coating is coated; and the second base coat coating contains a non-aqueous dispersion resin in a ratio of 5 to 80 mass % in terms of nonvolatile concentration based on a total resin nonvolatile concentration, wherein the total resin nonvolatile concentration relating to the second base coat coating is the total concentration of the nonvolatiles of the non-aqueous dispersion resin and other resins in the second base coat coating, and wherein the second base coat coating has a nonvolatile concentration of 25 to 35 mass % when coated, and the second base coat coating is a coating such that the second base coating film will have a nonvolatile concentration of 50 to 60 mass% when the second base coating film is formed.
