Abstract (en)

[origin: EP0459950A1] Process for improving the thermal and/or photochemical stability of dyed and undyed polyamide fibres by treatment with a composition from an aqueous bath containing (A) a compound of the formula (1) (A-Y-)nZ(-W)m in which   A denotes the radical of a sterically hindered phenol of the benzene series,   Y denotes a radical of the formula (2) or (3) <IMAGE> in which   X and X', independently of one another, denote alkylene, oxaalkylene or thiaalkylene,   R2 and R3, independently of one another, denote hydrogen or a substituted or unsubstituted alkyl group and   x, x' and y, independently of one another, are each 0 or 1,   Z denotes an aliphatic or a carbocyclic aromatic radical, the latter containing at most two mono- or bicyclic rings,   W denotes a sulpho group and   m and n, independently of one another, denote 1 or 2, and their water-soluble salts, and (B) a UV absorber.
