    摘要： An additive for cationic electrodepositable coating compositions is disclosed which improves hiding ability, stability, rheology and oil spot resistance. The additive is present in amounts of between 0.5 to 40 weight percent and is prepared by polymerizing in aqueous medium, under free radically initiated conditions, an aqueous dispersion of a polymerizable, ethylenically unsaturated monomer composition in the presence of a cationic polymeric surface active substance. The coating composition additionally has between 60 to 99.5 weight percent of a cationic salt group containing film forming polymer. Also disclosed is a method for coating which includes electrodepositing the above composition on an electrically conductive cathode.

    摘要： Electrodepositable coating composition bath is prepared and maintained to reduce the growth of bacteria in and around the bath. The composition has dispersed in an aqueous medium a resinous phase, said composition having a pH of at least 5, said resinous phase having basic nitrogen groups which are at least partially neutralized with an acid of the formula: ##STR1## wherein R is hydrogen or an alkyl group with one to four carbon atoms. The amount of this acid to neutralize the cationic resinous phase can be an initial amount greater than 90 of the milliequivalents of sulfamic acid based on the total milliequivalents of neutralizing acid in the bath for the electrodeposition coating of articles in the bath. Also, the bath is maintained by post addition of sulfamic acid to a level of greater than 80 weight percent of the milliequivalents of neutralizing acid when the bath has less than or greater than 90 weight percent of the milliequivalents of neutralizing acid in the bath as sulfamic acid.
