Abstract

A two-phase cathodic electrocoat is obtainable by coating an electrically conducting substrate with a mixture containing A) an aqueous cationic dispersion of a polycondensation or polyaddition product, B) an aqueous cationic dispersion of a polycondensation or polyaddition product having a glass transition temperature of from -80 to 20°C, the polymers of dispersions (A) and (B) being mutually incompatible, and C) optionally a crosslinking agent, a pigment paste, auxiliaries and/or additives, and then baking.
