Auxiliary agent mixture and its use in dyeing polyester fibre materials

Abstract

Abstract Dyeing auxiliary mixture comprising (A) a dicarboxyimidoester of the formula <IMAGE> where W is a dicarboxylic acid radical of at least 2 carbon atoms, R is an aliphatic, araliphatic or cycloaliphatic radical of not more than 24 carbon atoms and n is from 2 to 5, (B) an acid ester or salt thereof of an alkylene oxide adduct of the formula <IMAGE> where V is hydrogen or methyl, X is the acid radical of an inorganic oxygen atom containing acid or the radical of an organic acid, Y is an alpha -methylaralkyl radical, "Alkylen" is ethylene or propylene, m is from 1 to 3, m1 is 1 or 2 and n1 is from 4 to 50, and (C) a nonionic surfactant. The auxiliary mixture is suitable in particular for a rapid dyeing process for polyester fibre textile material, producing a rapid increase in the rate of migration of the disperse dyes.
