ABSTRACT:
Concentrated aqueous dye solutions, which comprise 5 to 50% by weight of at least one dye of formula (1) ##STR1## wherein X and Y are each independently of the other hydrogen or C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy, and Z is C.sub.2 -C.sub.6 alkanoylamino or C.sub.2 -C.sub.4 hydroxyalkylsulfamoyl,
M.sup.+ is the ammonium cation ##STR2## of an amine of formula ##STR3## wherein R.sub.1 and R.sub.2 are each independently of the other hydrogen, C.sub.1 -C.sub.6 alkyl, or hydroxy- or amino-substituted C.sub.2 -C.sub.6 alkyl which may be interrupted by an oxygen atom, and R.sub.3 is hydroxy- or amino-substituted C.sub.2 -C.sub.6 alkyl which may be interrupted by an oxygen atom, with the proviso that R.sub.1, R.sub.2 and R.sub.3 are not a radical of formula --CH.sub.2 --CH(OH)--CH.sub.3 if X and Y are methyl and Z is 2-hydroxyethylsulfamoyl or if X and Y are hydrogen and Z is propionylamino, have good storage stability and give dyeing having good fastness properties on hydroxyl group-containing or nitrogen-containing fibre materials.
