Abstract
An aqueous aerosol coating composition, which includes a thermoplastic acrylic polymer solubilized in an aqueous solution of a monohydric alcohol. The coating composition may further be blended with a controlling amount of a water soluble or water reducible acrylic polymer for imparting a desired degree of gloss and alkali resistance to a coating made from the aqueous aerosol coating composition. The compositions of this invention provide for improved drying rates, hardness and alkali resistance over current aqueous systems.
