ABSTRACT:
A thermally curable aqueous emulsion coating composition is provided in which the discontinuous phase of the emulsion is constituted by liquid particles of a mixture of resinous polyepoxide and 2-hexoxy ethyl ether of an aminoplast resin, dissolved in an essentially water immiscible organic solvent. A surfactant, which is preferably nonionic, is used to stably suspend the liquid particles in the aqueous continuum. The etherification of the aminoplast resin with 2-hexoxy ethanol serves to provide improved retention of cure capacity on storage.
