ABSTRACT:
Water-soluble or water-dispersible resinous salts are prepared by `tipping` an epoxy resin with a phenol, then carrying out a Mannich reaction with an aldehyde (usually formaldehyde) and an aminosulfonic or aminophosphonic acid, followed by salt formation on the free acid groups, preferably using an aliphatic amino alcohol, e.g., 2-dimethylaminopropan-1-ol.
Such salts may be crosslinked by heating in the presence of an aminoplast, a phenol-formaldehyde resin or a blocked polyisocyanate or, when the salts contain free methylol groups, by heating alone. They can be used for preparing coating compositions.
