ABSTRACT:
An electrocoating process in which a layer of an electrically conductive cathodic electrocoating composition containing film forming binder and pigment in a pigment to binder weight ratio of about 1:100 to 100:100, wherein the pigment comprises an electrically conductive pigment of silica which is either amorphous silica or a silica containing material, the silica is in association with a two-dimensional network of antimony-containing tin oxide crystallites in which the antimony content ranges from about 1-30% by weight of the tin oxide is electrocoated onto a metal substrate and cured to form a coated substrate, wherein the resulting layer has a resistance of less than 10.times.10.sup.15 ohms, a layer of a clear cathodic electrocoating composition is electrocoated over the layer of the conductive composition and the layer clear composition is cured to form a clear layer on the substrate.
