ABSTRACT:
A bath composition for cataphoretic electrocoating of conductive surfaces contains coating agents which have been rendered soluble or dispersible with acid, contain basic nitrogen groups and carry groups of the general formulae (1) and (11) ##STR1## and, optionally, also groups of the general formulae (III) and/or (IV) ##STR2## where R.sup.1 and R.sup.2 are each alkyl, hydroxyalkyl or alkoxyalkyl, R.sup.3 and R.sup.4 are each hydrogen or methyl, R.sup.5 and R.sup.6 are each hydrogen, alkyl or a divalent radical of a polymer molecule which is bonded to a phenol or phenol ether, n.sup.1 is 1, 2 or 3 and n.sup.2 is 1 or 2, and where the oxygen bonded to the phenyl radical is either in the form of the OH group or etherified.
