A stable, aged composition suitable for depositing a coating by electrophoresis comprising an aqueous dispersion of a mixture of from about 2% to about 60%, by weight, of (A) polymeric substantially water-insoluble, substantially fully etherified polymethylol melamines or guanamines and correspondingly from about 98% to about 40%, by weight, of (B) a water dispersible non-gelled polymeric material carrying an ionic charge which polymeric material contains at least one class of reactive groups, alcoholic hydroxy groups and amide groups wherein the amount of said groups is at least about 3%, by weight, and not more than about 30%, by weight, based on the total weight of said polymeric material wherein said groups are heat reactive with (A) wherein said percentages of (A) and (B), by weight, total 100% and are based on the total solids weight of (A) and (B).
