Abstract
A process for the production of cationic paint binders which are particularly suitable for formulating pigment pastes for cathodically depositable electrocoating paints is described. The paint binders produced according to the invention are modified epoxy resin-amine adducts which contain organically-chemically bonded titanium. The cured paint films provide excellent corrosion protection on non-pretreated sheet steel even in the absence of lead-containing compounds and/or lead pigments.
