Beschreibung
Zusammenfassung:	A method for removing odor from an aqueous solution of polymeric quanternary ammonium salt solution containing residual aliphatic tertiary amine and choline chloride or derivative thereof, said process comprising adding a sufficient amount of a non-volatile, stable, polybasic acid to react with said choline chloride or derivative thereto to prevent the formation of aliphatic tertiary amine from said choline chloride or derivative thereof. The present invention is also directed to a process for the preparation of recording film by treating as ethylene oxide neutralized conductive quaternary polymer solution with orthophosphoric acid and coating the treated solution directly onto a substrate.
