The invention relates to a process for preparing an organic solvent-based dispersion comprising a melt-blended network of an epoxy-functional and/or amino-functional polymer having a polymer-O&#x2014;Si&#x2014;O-polymer linkage and a polyolefin (co)polymer having carboxylic acid and/or carboxylic acid anhydride groups, the process comprising the steps of a) forming the melt-blended network from a prepolymer, a silane-functional compound and the polyolefin (co)polymer in the absence of a solvent, b) mixing the melt-blended network with an organic solvent to make the organic solvent-based dispersion, and c) cooling the organic solvent-based dispersion. The invention further relates to a coating composition and to a coated metal substrate.

The invention includes an aqueous coating composition having a substituted succinimide compound, wherein the substituted succinimide compound has an acid value of at least about 30 mg KOH/g of the substituted succinimide compound. The substituted succinimide compound may be the reaction product of an unsaturated oil comprising at least one non-aromatic unsaturated carbon-carbon bond, a polymer derived from the unsaturated oil, or a combination thereof with maleic anhydride and a primary amine.

Aqueous coating compositions including the reaction product of maleic anhydride with an unsaturated compound and an amine

Latex emulsions are disclosed which can be used in the formation of coating compositions that are not water sensitive, have good blush resistance and retortability. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Coating compositions can be prepared by mixing an ethylenically unsaturated monomer component and a stabilizer comprising a strong acid, in a carrier to form a monomer emulsion, reacting the monomer emulsion with an initiator to form the latex emulsion, and reacting the latex emulsion with a neutralizer. Methods of coating substrates with the coating compositions, and substrates coated with the coating compositions are also disclosed. The latex emulsions can be prepared by mixing an ethylenically unsaturated monomer component and a stabilizer comprising a strong acid, in a carrier to form a monomer emulsion, and reacting the monomer emulsion with an initiator to form the latex emulsion, wherein the stabilizer is present in an amount from about 0.1 to about 2.0 by weight polymeric solids.

Latex emulsions and coating compositions formed from latex emulsions

An aqueous ambient dry decorative or protective coating comprising a film forming matrix polymer of an aqueous emulsion polymer of aqueous copolymerized ethylenically unsaturated monomers modified with at least 3% by weight of a low molecular weight oligomer of copolymerized hydroxy alkanoic acid having 2 to 4 carbon atoms having a number average molecular weight between 300 and 10,000 to provide a film forming binder substantially free of volatile organic coalescing solvents. Preferred oligomers are homopolymers and copolymers of polymerized lactic acid or polymerized glycolic acid.
