Abstract

Novel monoazo compounds of the formula I ##STR1## and mixtures of these compounds with one another are described. The substituents X, R, R.sub.1, R.sub.2 and R.sub.3 are defined as follows: R is a phenyl or naphthyl radical which is unsubstituted or substituted by C.sub.1 -C.sub.4 -alkyl, or is a cycloalkyl radical which is unsubstituted or substituted by C.sub.1 -C.sub.4 -alkyl, or is a C.sub.1 -C.sub.8 -alkyl radical which is unsubstituted or substituted by cyano, halogen, phenyl or sulfophenyl, or is a propenyl radical which is unsubstituted or substituted by halogen, X is hydrogen or halogen, R.sub.1 is hydrogen or a C.sub.1 -C.sub.4 -alkyl radical, R.sub.2 is C.sub.1 -C.sub.8 -alkyl radical, a C.sub.1 -C.sub.4 -sulfatoalkyl radical, a C.sub.1 -C.sub.4 -sulfoalkyl radical or a cycloalkyl radical and R.sub.3 is a C.sub.1 -C.sub.4 -alkyl radical, or is a cycloalkyl radical which is unsubstituted or substituted by C.sub.1 -C.sub.4 -alkyl, or is a ##STR2## radical, in which the phenyl radical can also be substituted, by --SO.sub.3 H, with the condition that the molecule contains a sulfo group in R, R.sub.2 or R.sub.3 or a sulfato group in R.sub.2. The novel monoazo compounds are particularly suitable as dyes for dyeing and printing textile materials, in particular wool and polyamide.
