Abstract
Coating compositions are disclosed. In some embodiments, the coating compositions are used to coat substrates such as packaging materials and the like for the storage of food and beverages. The coating compositions can be prepared by reacting an epoxidized vegetable oil and a hydroxyl functional material in the presence of an acid catalyst to form a hydroxyl functional oil polyol, mixing the hydroxyl functional oil polyol (with or without epoxidized polybutadiene) and a functional polyolefin copolymer to form a mixture, reacting the mixture with an ethylenically unsaturated monomer component in the presence of an initiator to form a graft copolymer, and crosslinking the graft copolymer with a crosslinker to form the coating composition, wherein the graft copolymer or the crosslinked graft copolymer is inverted into water.
