- (B) a sulfonated phenol-formaldehyde condensation product, the weight ratio of A:B being in the range between about 5:95 and 95:5,
- said composition being useful for imparting resistance to staining of a nylon 6 or nylon 66 fibrous substrate by an acid dye.
- 2. The composition of claim 1 wherein said weight ratio is in the range between about 90:10 and 10:90.
- 3. The composition of claim 1 wherein said weight ratio is in the range between about 60:40 and 40:60.
- 4. The composition of claim 1 wherein at least 95 wt % of said maleic anhydride polymers have a number average molecular weight of about 700 to 200,000.
- 5. The composition of claim 4 wherein at least 95 wt % of said maleic anhydride polymers have a number average molecular weight of about 1000 to 100,000.
- 6. The composition of claim 1 wherein at least one of said 1-alkenes is isobutylene.
- 7. The composition of claim 1 wherein at least one of said 1-alkenes is 1-octene.
- 8. The composition of either claim 1, 2, 3, 4, 5, 6, or 7 wherein said polymer contains one polymer unit derived from maleic anhydride per polymer unit derived from one or more of said 1-alkene monomers.
- 9. The composition of claim 1 wherein up to 50 weight % of said alpha-olefin is replaced by one or more of C.sub.1 to C.sub.4 alkyl acrylate or methacrylate, vinyl acetate, vinyl chloride, vinylidene chloride, vinyl sulfide, N-vinyl pyrrolidone, acrylonitrile, or acrylamide, or mixtures of the same.
- 10. The composition of claim 1 wherein up to 75 weight % of said maleic anhydride is replaced by maleimide, N-alkyl (C.sub.1-4) maleimides, N-phenyl-maleimide, fumaric acid, itaconic acid, citraconic acid, aconitic acid, crotonic acid, cinnamic acid, alkyl (C.sub.1-18) or cycloalkyl (C.sub.3-8) esters of the foregoing acids or sulfated castor oil.
- 11. The composition of claim 1 wherein up to 30 weight % of the maleic anhydride is replaced by acrylic or methacrylic acid.
- 12. The composition of claim 1 wherein said alpha-olefin/maleic anhydride polymer or mixture thereof is hydrolyzed to the free acid or salts thereof by reaction with water or aqueous alkali.
- 13. The composition of claim 1 wherein said alpha-olefin/maleic anhydride polymer or mixture thereof is reacted with an alkyl alcohol containing 1 to 4 carbon atoms to give polymeric alpha-olefin/maleic acid monoesters.
