ABSTRACT:
The invention relates to monoazo dyes of the formula ##STR1## wherein K is the radical of a coupling component of the benzene, naphthalene or heterocyclic series, and R is hydrogen, halogen, carboxy, a C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, C.sub.2 -C.sub.6 alkanoylamino, C.sub.1 -C.sub.6 alkylsulfonylamino, C.sub.1 -C.sub.6 alkylsulfonyl, phenyl(C.sub.1 -C.sub.4)alkylsulfonyl or naphthyl(C.sub.1 -C.sub.4)alkylsulfonyl or benzoyl radical, which radicals may be further substituted, or is a ##STR2## group, wherein each of R.sub.1 and R.sub.2 independently of the other is hydrogen or a C.sub.1 -C.sub.6 alkyl, C.sub.5 -C.sub.7 cycloalkyl, phenyl or naphthyl radical, which radicals may be further substituted, and wherein X is hydrogen, halogen or a C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxy, C.sub.2 -C.sub.6 alkanoylamino or C.sub.1 -C.sub.6 alkylsulfonylamino radical, which radicals may be further substituted.
These dyes give dyeings of good light- and wetfastness properties on polyamide material.
