Abstract (en)

[origin: EP0475905A1] The process is characterised in that the wool is treated with an aqueous solution which contains at least one UV absorber of the formula <IMAGE> in which at least one of the substituents R1, R2 and R3 is a radical of the formula <IMAGE> in which   M is hydrogen; or a cation equivalent;   m denotes 1; or 2; and   the other substituent or substituents independently of one another denote amino; C1-C12-alkyl; C1-C12-alkoxy; C1-C12-alkylthio; C1-C12-alkylamino; di-C1-C12-alkylamino; phenyl; phenoxy; phenylthio; anilino; or N-phenyl-N-C1-C4-alkylamino. <??>The UV absorbers can be used in a wide pH range and effectively reduce yellowing of the wool.
