ABSTRACT:
Package and tank stable, low temperature self-curing, cation-active aqueous soluble or dispersible coating compositions are prepared by copolymerizing blocked meta-isopropenyl-.alpha.,.alpha.-dimethylbenzyl isocyanate (m-TMI) 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.
