Abstract
Stain-resistant compositions comprising sulfonated phenol-formaldehyde condensation products and polymers of maleic anhydride and one or more ethylenically unsaturated monomers, polyamide textile substrates treated with the same, and processes for their preparation. The stain-resistant compositions and substrates possess improved stain resistance but do not suffer from yellowing to the extent that previously known materials do.
