<p>IMPROVED VINYL RESIN METAL COATING COMPOSITIONS Vinyl and vinylidene halide resins containing carboxyl or sulfonic acid functionalities can be formulated as stable, aqueous, colloidal dispersions by converting them to ionomers in a mixture of watermiscible base, water, organic water-miscible macromolecular compound, water-miscible organic solvent having an affinity for the resin and water-miscible organic co-solvent which is a poor solvent for the resins and optionally a water-immiscible organic diluent and then stripping the mixture to a total organic solvent content of about 0.2 to about 20% by volume.
