ABSTRACT:
Blends of nylon 6,6, nylon 6 or nylon 6,6/6 copolymer which contain a randomly copolymerized cationic dye modifier are formed by melt blending such copolymer with a polyamide having 8 to 22 carbon atoms per amide link to form a block copolymer composition which is resistant to staining with acid dyes under ambient temperature and pH conditions.
