ABSTRACT:
Process for producing cationic epoxy resins carrying oxazolidine groups suitable as paint binders, and particularly paint binders for the formulation of cathodically depositable paints, wherein the epoxy resin is reacted with a hydroxy functional oxazolidine compound or with an oxazolidine compound carrying in the ring the structure ##STR1## in the presence of a monocarboxy compound. The presence of the monocarboxy compound permits the direct reaction or linkage of the epoxy resin with the oxazolidine compound without gelation; and, additionally, the monocarboxy compound favorably influences the film-forming characteristics of the binders.
