Abstract
Abstract The invention relates to polymeric coating compositions which are at least partially soluble in water. Polyesters, polyesterimides, polyesteramides, polyesteramideimides, polyester hydantoins and polyester urethanes are prepared with free carboxyl or carboxylic acid groups. At least part of the carboxylic acid groups are neutralized with amine containing material producing a coating composition which is at least partially soluble in water. The coating compositions are particularly useful as electric insulating coatings or wire enamels which are readily coated on a metallic or other substrate and when cured from coatings having good electrical and physical properties.
