  • Patent number: 3956091
    Abstract: Water-dispersed coating compositions which can be applied by electrodeposition contain an at least partially-neutralized acrylic interpolymer, an amine-aldehyde condensation product, and a methylol phenol ether composition of the formula: ##SPC1##Where n is an integer of from 1 to 3, and R is an unsaturated aliphatic group or a halogenated derivative of such a group. These compositions are easily and efficiently applied by electrodeposition to metal containers to provide uniform, hard, adherent coatings characterized by reduced sulfide staining when compared to compositions without the methylol phenol ether.
