Abstract

A two-component concentrate which includes an aqueous dispersion of a cathodically depositable binder having groups comprising active hydrogen that are cross-linkable using blocked polyisocyanate, as the binder component, and an anhydrous, organic solution of an oxime-blocked isocyanate-functional adduct of aromatic polyisocyanate and at least one compound comprising at least one group capable of addition towards isocyanate and at least one tertiary amino group, as the cross-linking component is used for the preparation of cathodic electrodeposition coating compositions.
