An aerosol paint system is provided under sprayable pressures in a pre-packaged container adapted for instant spray application. The paint composition comprises a water-soluble monomer modified alkyd resin binder composition having a low molecular weight less than about 10,000 and an acid value (before neutralization) of above about 30 and preferably less than about 80. The product is diluted so that it is in a ready-to-use form when purchased. The paint system may be pigmented or non-pigmented (as for use in clear transparent coatings). Spray coatings of this invention deposit continuous films from pressurized containers at will. Operable formulations comprise monomer modified alkyd resin binders made water-soluble by neutralization with bases in solution in aqueous solutions of water-soluble volatile organic solvents which may include a first group consisting of low molecular weight alcohols, ketones and esters and a second group of higher molecular weight co-solvents characterized by co-solvency and known as Cellosolves, cellosolve acetates, other esters and Carbitols. The second class is useful, but not essential. The coatings of this invention may contain prime (hiding) pigments, corrosion resistance pigments and inert pigments. All are well known to provide various colors, gloss control and other known effects. They are also useful in non-pigmented form for clear coatings. As the volatiles are predominantly water, fire hazards in storage and use are minimal.

A protective and decorative aerosol coating composition adapted for application from a pre-packaged pressurized spray container which comprises from about 15% to about 40% by weight of water as the principal solvent phase; from about 5% to less than 30% by weight of a water-soluble, volatile organic solvent selected from the group consisting of alcohols, ketones and/or esters and admixtures thereof, having less than six carbon atoms in their chemical structures, from about 20% to about 45% by weight of a liquified propellant under pressure, the major proportion of which is an oxygenated ether selected from the group consisting of methyl ethyl ether, dimethyl ether, propylene oxide 1-3 and propylene oxide 1-2; from about 5% to about 20% by weight of a non-volatile, substantially water-soluble, film-forming, monomer-modified organic polyester polymer whose normal acid value is greater than 30 and not more than about 80, which acid value is neutralized with a base selected from the group consisting of ammonia, amines, basic inorganic lithium compounds and admixtures thereof, and from 0 to about 15% by weight of a paint pigment dispersed in said aqueous solution above; said neutralized aqueous polymer solution being substantially free from insoluble polymer particulates greater than 0.1 microns in diameter.
