Abstract
Water-dilutable, cationically stabilized epoxy resins ZYX are obtained by reacting, in the first stage, aromatic or aliphatic epoxide compounds Z with aliphatic amines Y to form epoxy-amine adducts ZY which are neutralized and then in aqueous dispersion are reacted in a second stage with a further epoxy resin X. The resins ZYX may be formulated without additional curatives to give aqueous coating materials which exhibit a good corrosion protection effect.
