Abstract
Package and tank stable low temperature self-curing cation-active aqueous soluble or dispersible coating compositions are prepared by polymerizing blocked isocyanatoethyl methacrylate (IEM) alone or copolymerizing with various vinyl unsaturated monomers optionally in the presence of epoxy-amine adduct. These cation-active polymers when acidified or partially acidified provide aqueous solutions or dispersions especially useful as low temperature curable vehicles in cathodic electrocoating.
