Abstract
A coating composition comprising a resinous binder and up to 10 percent by weight of a phosphatized polyester. The compositions are useful for coating containers of all sorts such as food and beverage containers, and the phosphatized polyester provides enhanced adhesion of the coating to the container substrate. The compositions can be formulated to be substantially free of bisphenol A (BPA) and bisphenol A diglycidyl ether (BADGE).
