ABSTRACT OF THE DISCLOSURE Water-soluble disazo compounds of the general formula (1) Image (1) in which R1 and R2, identical to or different from each other, are each a hydrogen atom, an alkyl group of 1 to 4 carbon atoms, an alkoxy group of 1 to 4 carbon atoms or a chlorine atom, R is a hydrogen atom or an alkyl group of 1 to 4 carbon atoms, an alkoxy group of 1. to 4 carbon atoms or a sulfo group, M is a hydrogen atom or one equivalent of a metal, X is vinyl or .beta.-sulfatoethyl group, Y is a chlorine atom or a fluorine atom with the proviso that, if Y is chlorine, D is a phenyl radical which can be substituted by 1, 2 or 3 substituents from the group consisting of alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, halogen, trichloro- methyl, trifluoromethyl, nitro, alkanoylamino having 1 to 4 carbon atoms in the alkyl radical, benzoylamino which can be substituted in the benzene nucleus by one or two substituents from the group consisting of methyl, ethyl, methoxy, ethoxy, chlorine and sulfo, phenylsulfonylamino which can be substituted by one or two sub- stituents from the group consisting of methyl, ethyl, methoxy and ethoxy, carboxy and sulfo, where this phenyl radical D preferably contains at least one sulfo group or carboxy group as substituent, or D is a naphthyl radical which is substituted by 1, 2 or 3 sulfo groups, and i-f Y is fluorine, D is phenyl unsub- stituted or substituted by 1, 2 or 3 substituents selected from the group consisting of carboxy, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, halogen, trichloromethyl, trifluoro- methyl, nitro, alkanoylamino having 1 to 4 carbon atoms in the alkyl moiety, benzoylamino unsubstituted or substituted in the benzene nucleus by 1 or 2 substituents selected from the group consisting of methyl, ethyl, methoxy, ethoxy, chlorine and sulfo, and phenyl- sulfonylamino unsubstituted or substituted by 1 or 2 substituents selected from the group consisting of methyl, ethyl, methoxy and ethoxy, or D is naphthyl substituted by 1, 2 or 3 sulfo groups, and the moieties R1, R2, R, Y and the substituents in D can be identical to or different from one another. These novel disazo compounds can be prepared analogously to known methods from the components evident from the formula (1) (the aniline compound with the group -SO2-X, the cyanuric halide, the phenylenediaminesulfonic acid, the aminonaphtholdisulfonic acid as bivalent coupling component and the amino compound D-NH2 as second diazo component). They have fiber-reactive dyestuff pro- perties and give on hydroxy- and/or carboxamide-containing material, in particular fiber material, such as cellulosic fibers, strong dyeings having good fastness properties.
