摘要：
A method of imparting acid dye stain resistance to polyamide substrates having improved durability of the stain resistance to detergent washings comprising treating the polyamide substrate with an effective amount of a mixture of phenyl vinyl ether/maleic diacid copolymer and 2-(4-hydroxymethyl-phenoxy)-ethyl vinyl ether/maleic diacid copolymer, wherein the phenyl vinyl ether/maleic diacid copolymer is the stain resist agent, and the 2-(4-hydroxymethyl-phenoxy)-ethyl vinyl ether/maleic diacid copolymer is added to improve the durability of the stain resist agent.
