    Abstract: Stable and homogeneous aqueous formulations of surfactants with an HLB of less than or equal to 13, which additionally contain a compound of the formula I in which R is C1-C8-alkyl, C1-C8-alkenyl, phenyl, alkylphenyl or phenalkyl with, in each case, 1 to 4 C atoms in the alkyl chain or cyclohexyl, R is hydrogen, or one of the radicals mentioned for R or R and R together with the N atom denote a heterocyclic radical, M is an alkali metal or ammonium cation or an equivalent of an alkaline earth or aluminium cation, and m and n are each, independently of one another, numbers from 6 to 8. The presence of the compounds of the formula I makes it possible to prepare stable and homogeneous aqueous formulations even of those surfactants which are otherwise only sparingly soluble or even insoluble in water.

    Abstract: Process for dyeing textile material with pigment dyes, which comprises 1. pretreating the textile material with a polymer which consists wholly or partly of monomeric units of the formula I (I) where R1 and R2 are each hydrogen, (C1-C22)alkyl which may be interrupted by -CO-NH- or -NH-CO-, or C1-C4-hydroxyalkyl, R3 and R4 are each hydrogen or methyl, and Y-is a monovalent anion or one equivalent of a polyvalent anion, 2. then dyeing with a pigment dye in the presence of a leveling or dispersing agent by the exhaust method and if necessary 3. treating the dyeing in a liquor with a pigment binder and subsequently fixing it. This process makes it possible to dye textile material, in particular ready-made jeans garments, with pigment dyes by an exhaust method.
