ABSTRACT:
Novel compounds produced by reacting 5-sulfoisophthalic acid or a salt thereof (e.g. the potassium salt) with a water soluble copper salt (e.g. cupric acetate monohydrate) are described. The compounds are effective antiozonants for polyamide fibers, particularly, when the fibers are dyed with disperse dyes. Generally, sufficient amounts of the compounds are incorporated into the fibers to provide from 10 to 100 ppm, on weight of fiber, of copper.
