ABSTRACT:
Polyamide substrates treated with stain-resists which comprise blends of maleic anhydride/alpha-olefin polymers and sulfonated phenol-formaldehyde condensation products. Some of the stain-resist blends are water-soluble at low pH, even in the absence of surfactant, and are strongly substantive and more resistant to yellowing than the condensation products.
