    Abstract: A water-based coating composition which emits very little pollutants on curing to a water-resistant coating comprises a synthetic resin containing free carboxyl groups held in solution or stable dispersion in water by an amine. The amine is a tertiary carbinamine containing at least two hydroxymethyl groups bonded to the carbon atom carrying the amine group. The coating compositions react with formaldehyde to produce stable fluid emulsion coating compositions having similar properties on curing. The coating compositions are used to coat substrates.

    Abstract: Monoethylenic monomers, including from about 1 to about 30% by weight of monoethylenic carboxylic acid, are placed in solution in a liquid mixture preferably containing a low molecular weight polyhydric alcohol and an anionic surfactant and this liquid mixture is dispersed in water containing a C.sub.3 -C.sub.4 alkanol and polymerized in the presence of an organic peroxide free radical polymerization catalyst at an elevated temperature, while agitating the dispersion. The dispersion of polymer particles is then at least partially neutralized, preferably with ammonia or an amine, to form an aqueous dispersion which is stable and which is useful in electrocoating.
