A method is provided for forming high-appearance multi-layer coating films by sequentially providing an undercoating film with a water-based intermediate coat and a topcoat while controlling the imbibing or inversion at each interface between the respective coating films. n The method comprises forming an intermediate coat using a water-based intermediate coating, a metallic base coat using a water-based metallic base coating and a clear coat using a clear coating in that order on a substrate provided with an electrodeposited coat n wherein the water-based intermediate coating contains an aqueous dispersion of amide group-containing acrylic resin particles having a particle diameter of 0.01 to 1.0 μm as obtained by emulsion polymerization of an amide group-containing, ethylenically unsaturated monomer with another ethylenically unsaturated monomer or monomers or monomers. |
