Abstract

Monoazo compounds conforming to the general formula (1) shown and defined hereinafter have very good fiber-reactive dye properties and dye hydroxy- and/or carboxamido-containing material, in particular fiber material, such as wool and in particular cellulose fibers, in strong fast shades. ##STR1## where the symbols have the following meanings: D is a benzene or naphthalene ring or a heterocyclic radical, PA0 R.sup.1 and R.sup.2 are each independently of the other hydrogen, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, halogen, carboxy or sulfo, PA0 Z is a fiber-reactive grouping bonded to D either directly or via a bridge member, PA0 m stands for the number 1 or 2, preferably 1, PA0 R is alkyl of 1 to 4 carbon atoms which may be substituted for example by halogen, such as bromine and in particular chlorine, hydroxy, cyano, sulfo, carboxy, sulfato or phosphato, or is phenyl which may be substituted, for example by 1 or 2 substituents from the group consisting of methyl, ethyl, methoxy, ethoxy, chlorine, sulfo and carboxy, or is carboxy, carbamoyl or carbalkoxy of 2 to 5 carbon atoms, PA0 n stands for the number 2 or 3.
