Abstract
An improved process for preparing with the aid of organic cosolvents water-dilutable, heat-curing coating compositions comprises (a) reacting an aromatic polyglycidyl ether with a polyethylene glycol in the presence of 10 to 30% of a polyhydric phenol, (b) adding an aminoplast curing agent, and (c) diluting with water to give a stable aqueous or aqueous organic composition. The process gives compositions which are useful in preparing coatings for a wide variety of substrates.
