This invention describes a process for preparing a self-emulsifiable epoxy ester copolymer mixture which comprises esterifying a solvent-soluble carboxyl-functional polymer with an epoxy resin which is a mixture comprising aromatic polyethers containing oxirane functionality, at least 5% of the aromatic polyethers being constituted by diepoxide, the mixture of aromatic polyethers constituting at least 40% of the total resin solids content and providing oxirane functionality in a stoichiometric deficiency with respect to carboxyl funtionality in the carboxyl-functional polymer of from 1:2 to 1:; 20, the esterification being carried out in organic solvent medium in the presence of greater than 2% of an amine esterification catalyst, based on the weight of the reactants subjected to esterification, and at an elevated temperature sufficient to cause the oxirane functionality to react with the carboxyl functionality until the oxirane functionality is substantially entirely consumed and reacting at least a portion of the carboxyl functionality in the resultant polymer-epoxy resin hydroxy ester reaction product with a base to render this action product self-emulsifiable in water.
