ABSTRACT:
A conductive substrate as cathode is coated by electrodeposition using a coating material which comprises a sterically stabilized dispersion of film-forming polymer particles in an aqueous medium, the polymer comprising or being associated with a stabilizing polymeric non-ionic hydrophilic moiety which is solvated by the aqueous medium and being free from stabilizing ionic charges. The dispersion of film-forming polymer particles has a critical coalescence value which is more negative than -0.3 units.
