Abstract
Abstract There is disclosed an emulsion coating composition having water dispersed in an organic solvent soluble resin and solvent through the use of an emulsifier having a hydrophile-lipophile balance of from two to about six. The composition may be mixed with a hydrocarbon propellant miscible in the continuous phase in suitable containers to produce a non-foaming water containing aerosol spray paint or varnish.
