Abstract: A coating composition is provided that is preferably substantially free of bisphenol A. The coating composition is useful in coating metal substrates such as, for example, interior and/or exterior surfaces of food or beverage cans. In some embodiments, the coating composition is formulated using an acrylic polymer that is formed form ingredients that do not include styrene.
