Abstract
A method for cationic electrocoating which comprises electrocoating a substrate in an electrocoating composition comprising an electrocoating resin having a reactive group admixed with a paste comprising a chromate pigment in a water-insoluble or hardly soluble, reactive group-containing organic binder and said paste having a water content of not more than 2% by weight and said composition having a concentration of 200 to 5,000 ppm in terms of CrO.sub.3, the reactive group in the electrocoating resin being crosslinkable with the reactive group in the organic binder. The formed electrocoating film has high rust prevention.
