Abstract
Abstract An aerosol paint composition is provided which is composed of a dispersion of an alkyd or polyester resin, containing a pigment, in a liquid medium. The liquid medium has two components the first of which is a mixture of 30 to 50 percent of an aromatic hydrocarbon and 50 to 70 percent of a halogenated hydrocarbon, the mixture having a boiling point between 70 DEG - 150 DEG C, and, the second of which is a liquified normally gaseous halogenated hydrocarbon having 1 to 4 carbon atoms and a boiling point below about 25 DEG C.
