This application discloses dimethyl ether propelled water based aerosol compositions. Classes of aqueous thickeners are described herein which are suitable for use in aqueous aerosol coating compositions. The thickeners lose their thickening capability in the presence of dimethyl ether which is the aerosol propellant employed, and thus allows a low enough temporary viscosity to afford suitable flow and breakup when dispensed in spray form from an aerosol dispenser. On evaporation of the dimethyl ether during the spraying process, enough of the dimethyl ether is lost to allow the thickener to regain its thickening capability. High gloss, thick film, aerosol paints can thus be achieved.

A propellant pressurized aerosol water based paint composition suitable for being sprayed from the valve of an aerosol dispenser, to provide a paint film capable of adhering to a vertically disposed substrate without running, comprising a water based paint concentrate under propellant pressure of dimethyl ether, wherein a portion of said dimethyl ether is dissolved in said concentrate, and said concentrate comprises water having at least one polymeric film former uniformly dispersed or dissolved therein, and said concentrate further includes at least one thickening agent which loses its ability to thicken said concentrate when said portion of dimethyl ether is dissolved in said concentrate, but regains its ability to thicken said concentrate upon dissolution of said dimethyl ether from said concentrate when said concentrate is sprayed from said aerosol dispener and applied as a film to a substrate.
