    摘要: Disclosed is a coating method of intermediate-coating-less, which sufficiently keeps excellent appearance, weather resistance and corrosion resistance equal to a three layer coating in conventional technology. The method of the present invention comprises: electrocoating an aqueous paint composition comprising at least two sort of resins which are insoluble with each other, a curing agent and a pigment, on an electrically conductive substrate, heating it to form a layer separation, and then curing to form a plural layered cured coating having at least two layers, wherein a concentration of the pigment is distributed such that a pigment concentration (a) in the resin layer directly contacting air is relatively higher than a pigment concentration (b) in the resin layer directly contacting the electrically conductive substrate.
