Abstract
A coating composition comprising a resinous binder and up to 10 percent by weight of the reaction product of (i) a phosphorus acid, and (ii) a polyglycidyl ether of cyclohexane dimethanol. The compositions are useful for coating containers of all sorts, such as food and beverage containers, and the reaction product provides enhanced adhesion of the coating to the substrate. The compositions can be formulated to be substantially free of bisphenol A (BPA) and derivatives thereof such as bisphenol A diglycidyl ether (BADGE).
