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.

Abstract: The invention provides nitrogen-containing basic binders having tertiary amino groups. They are produced from compounds or resins having at least one secondary amino group through reaction with a compound which contains both an epoxy group and an olefinic double bond, followed by copolymerization of the reaction product with a polymerizable monomer having an ethylenic double bond. The binders have amine numbers of about 40 to 400. They can be diluted with water after partial neutralization by acid. They are electrically depositable on the cathode and can be heat hardened alone or in combination with amino resins and/or phenolic resins. They can be used as internal and/or external cross-linking components in cathodic electrocoating paints.

Abstract: Alkoxyoctadienes are brominated with bromine to alkoxytetrabromoctanes of high purity by adding the bromine to an aqueous suspension of the alkoxyoctadienes at 0.degree.-40.degree. C.
