Abstract
A process is provided for coating an electrically conductive substrate with an aqueous coating composition containing a cationic binder wherein the binder is obtained by polymerization of 100 parts by weight of a specific monomer mixture in the presence of 1-20 parts by weight of an epoxy group-free adduct of a bisphenol bisglycidyl ether and an ethylenically unsaturated amido amine. The ethylenically unsaturated amido amine, in turn, is the product of a polyamine having 1-2 primary amino groups and 1-2 secondary amino groups and an ethylenically unsaturated monocarboxylic acid having 18-24 carbon atoms. The invention also pertains to the aqueous coating composition as such.
