Abstract

An aqueous cationic surface-coating system contains an olefinically unsaturated surface-coating binder having basic nitrogen groups, some or all of which are converted into salts with acid, a Co, Mn, Pb, Ce, Zr, Ca, Zn, Fe, Al, Cu, Ni or Cd complex, if appropriate in combination with an inhibitor and/or an initiator which supplies free radicals. This surface-coating system can be used for cathodic electrocoating or for conventional methods of surface-coating.
