Abstract
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.
