Abstract

Abstract Anionic araliphatic compounds which correspond to the general formula ##STR1## wherein A is a mono- or binuclear aromatic radical, R is alkyl having 4 to 22 carbon atoms, X is alkyl having 1 to 18 carbon atoms, of Z 1 and Z 2 , one is hydrogen and the other is hydrogen or methyl, M is a cation, and n is 1 to 21; these compounds are particularly useful as dyeing auxiliaries, especially as levelling agents, in the dyeing or printing of synthetic polyamide fibres with anionic dyes.
