Abstract
Processes and compositions which at the same time impart resistance to staining of polyamide substrates caused by acid dyes and improved durability to shampooing and resistance to yellowing caused by exposure to UV and/or NO.sub.x, whereby the stain-resist performance of hydrolyzed maleic anhydride copolymers can be dramatically improved either by co-applying the stain with a water-dispersed epoxy resin or by post-treatment of the stain-resist-treated polyamide fiber substrate with a water-dispersed epoxy resin.
