Abstract

Process for dyeing textile material with pigment dyes, which comprises PA0 1. pretreating the textile material with a polymer which consists wholly or partly of monomeric units of the formula I ##STR1## where R.sup.1 and R.sup.2 are each hydrogen, (C.sub.1 -C.sub.22)alkyl which may be interrupted by --CO--NH-- or --NH--CO--, or C.sub.1 -C.sub.4 -hydroxyalkyl, PA0 R.sup.3 and R.sup.4 are each hydrogen or methyl, and Y.sup.- is a monovalent anion or one equivalent of a polyvalent anion, PA0 2. then dyeing with a pigment dye in the presence of a leveling or dispersing agent by the exhaust method and if necessary PA0 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.
