Abstract
A polyamide fibrous substrate having deposited on it an amount of a composition effective to impart stain-resistance comprising a water-soluble or water-dispersible maleic anhydride/allyl ether or vinyl ether polymer or a mixture of said polymers, and processes for preparing the substates. The maleic anhydride polymer is used either in hydrolyzed form.
