    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.
