ABSTRACT:
A waterborne coating composition contains a base neutralized, stable, aqueous dispersion of a hydroxyl functional acrylic polymer containing less than 1 percent acid, having a number average molecular weight ranging from about 500 to about 4500 and having an acid value of at least about 1.5 and no greater than about 10 is prepared from a vinyl monomer component containing at least about 50 percent 2-hydroxyethyl acrylate and at least one other comonomer. The proportion of each monomer is selected so that the resultant polymer forms stable dispersion in water without externally added surfactant. The coating composition also contains a crosslinking agent adapted to react with the hydroxyl groups of the acrylic polymer.
