Abstract
Abstract An aerosol latex paint formulation is provided by emulsifying a latex paint in a liquid propellant composition which is a hydrocarbon or a halogenated hydrocarbon and which contains a cationic surfactant which is an ethylene oxide adduct of certain amines. The formulation is placed in a container suitably equipped with a spray nozzle. Preferably a wetting agent is also incorporated in the liquid component to provide better paint application.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
156 words
An aerosol latex paint composition comprising an emulsion of a pigmented aqueous dispersion of a waterinsoluble vinyl acetate-acrylic copolymer resin in a liquid propellant containing a cationic surfactant having an HLB value of between 5 and 10, wherein the liquid propellant comprises 30 to 70 weight percent of the composition and is a hydrocarbon having 3 to 4 carbon atoms, a halogenated hydrocarbon having 1 to 4 carbon atoms, or mixtures thereof, and wherein the cationic surfactant has the formula ##STR4## wherein R is a straight chain alkyl, or a straight or branched chain alkyl or aralkyl, containing 7 to 24 carbon atoms, said R can contain a nitrogen atom as an amine linkage and up to two oxygen atoms as ester or ether linkages or as -OH groups, and m and n are integers of 0 to 4, with the sum of m and n equal to at least 1 and not greater than 4.
Claim 2
Dependent Claim
156 words
An aerosol latex paint composition comprising an emulsion of a pigmented aqueous dispersion of a waterinsoluble vinyl acetate-acrylic copolymer resin in a liquid propellant containing a cationic surfactant having an HLB value of between 5 and 10, wherein the liquid propellant comprises 30 to 70 weight percent of the composition and is a hydrocarbon having 3 to 4 carbon atoms, a halogenated hydrocarbon having 1 to 4 carbon atoms, or mixtures thereof, and wherein the cationic surfactant has the formula ##STR4## wherein R is a straight chain alkyl, or a straight or branched chain alkyl or aralkyl, containing 7 to 24 carbon atoms, said R can contain a nitrogen atom as an amine linkage and up to two oxygen atoms as ester or ether linkages or as -OH groups, and m and n are integers of 0 to 4, with the sum of m and n equal to at least 1 and not greater than 4.
