Latex emulsions are described, which can be used in the formation of coating compositions that are not sensitive to water, have good resistance to bleaching and retort sterilization. In some embodiments, the coating compositions are used to coat material substrates of cans and packaging for the storage of food and beverages. The coating compositions of the invention can be prepared by polymerizing at least one ethylenically unsaturated monomer component, a stabilizer comprising a strong acid and an initiator in a carrier to form an emulsion, polymerizing the emulsion with at least one component of ethylenically unsaturated monomer to prepare the composite latex emulsion, and react to the composite latex emulsion with a neutralizer to form the coating composition. The methods of the coating substrates with the coating compositions, and the substrates coated with the coating compositions are also described. |
