ABSTRACT:
An aqueous system for treating a film or coating containing water-dispersible polymeric material having water solubilizing sulfonate groups in its molecular structure, the system being effective for insolubilizing the sulfonate groups and enhancing the water resistance of the film, and having dispersed therein per 100 grams of water, from about 0.002 to about 0.5 gram-ion equivalents of a multivalent cation, and from about 0.1 to about 25.0 grams of water-dispersible polyurethane material, and preferably having a No. 2 Zahn cup viscosity of from about 15 to about 50 seconds.
