Abstract
An aqueous coating composition useful as electro-deposition coatings includes (A') an aqueous dispersion of a resin (A) having functional groups which are reactive toward isocyanate, and (B') an aqueous, solvent-free dispersion of a solubilized masked polyisocyanate (B). The coating is cured by baking at a temperature which regenerates the isocyanate groups.
