Beschreibung
Zusammenfassung:	Disclosed is a colorant treated ion exchange resin comprising at least 15% of exchangeable groups comprising at least one of an ion, a Lewis acid, or a Lewis base resulting from a colorant having a pKa or pKb of greater than 5 in an aqueous solution at 25< DEG >C, based on the total number of exchangeable groups. Also disclosed are heat transfer systems, assemblies, fuel cell systems and methods of maintaining a conductivity of less than 200 [mu]S/cm in a heat transfer fluid that employ the disclosed colorant treated ion exchange resins. Finally, a method of making the disclosed colorant treated ion exchange resins is provided.
