Novel monoazo compounds of the formula I <IMAGE> (I) and mixtures of these compounds with one another are described. The substituents X, R, R1, R2 and R3 are defined as follows: R is a phenyl or naphthyl radical which is unsubstituted or substituted by C1-C4-alkyl, or is a cycloalkyl radical which is unsubstituted or substituted by C1-C4-alkyl, or is a C1-C8-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, R1 is hydrogen or a C1-C4-alkyl radical, R2 is C1-C8-alkyl radical, a C1-C4-sulfatoalkyl radical, a C1-C4-sulfoalkyl radical or a cycloalkyl radical and R3 is a C1-C4-alkyl radical, or is a cycloalkyl radical which is unsubstituted or substituted by C1-C4-alkyl, or is a <IMAGE> radical, in which the phenyl radical can also be substituted, by -SO3H, with the condition that the molecule contains a sulfo group in R, R2 or R3 or a sulfato group in R2. The novel monoazo compounds are particularly suitable as dyes for dyeing and printing textile materials, in particular wool and polyamide. |
