Abstract

Water-dilutable binders which are self-crosslinking at room temperature, comprising reaction products ABF with epoxy-amine adducts A and formaldehyde resin formers B selected from phenols B1, (substituted) ureas B2, melamine B3, guanamines B4, and mixtures of said resin formers, with formaldehyde F or compounds which give off formaldehyde under the reaction conditions, may be formulated, following at least partial neutralization, to give aqueous coating materials which give coatings affording outstanding corrosion protection.
