Patent number: 4450258Abstract: The invention relates to polymeric coating compositions which are at least partially soluble in water and are particularly stable.Polyester, polyesterimides, polyesteramides, polyesteramideimides, polyesterhydantoins and polyester urethanes are prepared with free carboxyl or carboxylic acid groups. The carboxylic acid groups are neutralized with amine containing material, at least fifty percent excess amine being used, 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 form coatings having good electrical and physical properties. They are also useful in making laminates, composites, and the like.Type: GrantFiled: October 7, 1983Date of Patent: May 22, 1984Assignee: General Electric CompanyInventor: Denis R. Pauze

Patent number: 4247429Abstract: The invention relates to polymeric coating compositions which are at least partially soluble in water.Polyesterimides, polyesteramideimides, polyesterimidehydantoins and polyesterimide urethanes are prepared which have enhanced solubility in water.

At least some of the imide rings are then cleaved or split with amine material to enhance solubility in water. The compositions are particularly useful as electrical insulating coatings or wire enamels and can also be used in preparing laminates and composites and for general coating purposes.Type: GrantFiled: July 11, 1978Date of Patent: January 27, 1981Assignee: General Electric CompanyInventors: Denis R.
