Abstract
An aqueous dispersion of a tertiary amine terminated polyether and a carboxylic acid functional polymer. The tertiary amine terminated polyether is the product of the reaction of the epoxy group of an epoxy resin with the hydroxy group of a hydroxy functional tertiary amine and the carboxylic acid functional polymer is present in an amount sufficient to render the combination water dispersible. A process for producing the aqueous dispersion is also described, together with coating compositions based on the dispersion. These coating compositions are particularly useful in the lining of metal containers for food and beverages.
