Carboxylic acid-containing polymer/resole resin stain-resists |
摘要 |
A composition which provides polyamide substrates with resistance to staining by acid dyes comprising (A) carboxylic acid-containing stain-resist polymers selected from: (i) methacrylic acid polymers, or (ii) hydrolyzed copolymers of maleic anhydride with ethylenically unsaturated aromatics, alpha-olefins, alkyl vinyl ethers or alkyl allyl ethers or (iii) mixtures of (i) and (ii), and (B) resole condensates prepared by reacting bis(hydroxyphenyl)sulfone which contains no sulfonate or carboxylate groups with formaldehyde in the presence of an alkali metal hydroxide, at a bis(hydroxyphenyl)sulfone resole resin:carboxylic acid-containing stain-resist polymer weight ratio in the range between about 1:20 and 2.5:1.0 is disclosed. |
