Process for coating an electrically conductive substrate and an aqueous coating composition based on a cationic binder.

摘要

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 from a polyamine having 1-2 primary amino groups and 1-2 secondary amino groups and from an ethylenically un­saturated monocarboxylic acid having 18-24 carbon atoms. The invention also pertains to the aqueous coating composition as such.
