ABSTRACT:
The invention relates to thermosetting, cathodically depositable, aqueous electrocoating compositions which are produced by reacting a nitrogen base-containing binder, which contains tertiary amino groups and primary and/or secondary OH groups, with metal compounds, which are sparingly soluble or insoluble in water, of cobalt, copper, lead, nickel and/or manganese at temperatures between 100.degree. C. and 150.degree. C. under an inert gas. The resultant products are subsequently protonated with an acid and diluted with water in a manner known per se to yield electrocoating paints having a solids content of from 5 to 25% and pH values of 5 to 8. Octoates, naphthenates, borates, and also acetyl acetonates are preferred to be used as the metal compounds which are sparingly soluble or insoluble in water.
