Abstract
Cataphoretic electrodeposition baths for coating ferrous metal articles, particularly untreated ferrous metal articles, are disclosed. The baths comprise aqueous dispersions of cationic electrodepositable resins and lead ions which are introduced into said bath by the addition of water-soluble lead compounds. Coatings electrodeposited on ferrous metal articles from such baths have excellent corrosion resistance.
