## Abstract

This invention relates to aerosol paint and coating compositions comprising non-aqueous dispersions.

## Claims

### Claim 1

A composition suitable for being dispensed from a pressurized aerosol container comprising a non-aqueous dispersion of addition polymers in an alkyd medium and a propellant.

### Claim 2 (depends on 1)

The composition of claim 1 wherein said non-aqueous dispersion is the reaction product of two or more monomers polymerized in the presence of said alkyd via the free radical addition mechanism.

### Claim 3 (depends on 2)

The composition of claim 2 wherein at least one of said monomers is selected from the group consisting of acrylonitrile, methacrylonitrile, hydroxy ethyl acrylate and methacrylate, methyl acrylate and methacrylate, acrylamide, methacrylamide, vinyl chloride, vinylidene chloride, acrylic acid, methacrylic acid, itaconic acid, maleic acid, fumaric acid, the methyl esters of itaconic, maleic and fumaric acid, and mixtures thereof; wherein at least one of said monomers has hydroxy-functionality; and wherein said polymerization is conducted in the presence of a chain transfer agent.

### Claim 4 (depends on 3)

The composition of claim 3 wherein between about 5% and 35% by weight of the reactor solids comprises at least one monomer having hydroxy functionality.

### Claim 5 (depends on 4)

The composition of claim 4 wherein said hydroxy functional monomer is selected from the group consisting of hydroxy ethyl acrylate and hydroxy ethyl methacrylate, and mixtures thereof.

### Claim 6 (depends on 5)

The composition of claim 5 wherein said monomer charge comprises methyl methacrylate and hydroxy ethyl acrylate.

### Claim 7 (depends on 6)

The composition of claim 6 wherein said chain transfer agent is selected from the group consisting of methyl mercaptopropionate, dodecyl mercaptan and 2-mercapto ethanol.

### Claim 8 (depends on 1)

The composition of claim 1 wherein the propellant is selected from the group consisting of aliphatic hydrocarbons having from 1 to 4 carbons, chlorofluorocarbons, dimethyl ether, and mixtures thereof.

### Claim 9 (depends on 8)

The composition of claim 8 wherein the propellant is selected from the group consisting of propane, butane, isobutane and mixtures thereof.
