ABSTRACT:
An aqueous coating composition that is particularly adapted for repairing defects in coated metal articles comprises an aqueous dispersion having as its major ingredient an epoxy phosphate ester polymer, a cross-linking agent for the epoxy phosphate ester polymer which may be an aminoplast or phenoplast resin, and an effective quantity of an organic solvent having a solubility parameter in the range of 8.5-10 and being soluble in water at 20.degree. C. to the extent of less than 10%. The composition is desirably electrocoated upon the object at a temperature in the range of from 80.degree. to 120.degree. F. and preferably from about 90.degree.-100.degree. F.
