Abstract of the Disclosure Acid esters of propylene oxide poly-adducts and their salts, which are obtained by an addition reaction of (a) propylene oxide with (b) a polyfunctional amine, which contains 2 to 9 carbon atoms and at least a second reactive amino group or at least one hydroxyl group, and esterification of the poly- adduct with (c) an oxy-acid which is at least dibasic or with a functional derivative of this acid and, if appropriate, by conversion of the resulting acid ester into a salt. These acid esters of propylene oxide poly-adducts are particularly effective as dyeing auxiliaries, especially as dispersing and levelling agents for dyeing synthetic fibres and primarily for dyeing linear polyester fibres.
