Abstract: New copper-complex formazan compounds of the general formula: in which A is a phenylene or naphthylene radical which can be substituted by halogen, nitro, lower alkyl, lower alkoxy, lower alkylsulfonyl, phenylsulfonyl and optionally alkylated sulfonamide groups and can also be substituted by the radical Z, defined below, B is a straight-chain or branched-chain alkyl group or alkenyl group, which can be substituted by an optionally substituted phenyl radical, or is a phenyl or naphthyl radical, which can be substituted by halogen, lower alkyl, lower alkoxy and lower carbalkoxy, or is the radical or a furan, thiophene, pyrrole, imidazole, indole, pyrazole, pyridine, pyrimidine, quinoline or benzimidazole, it being possible for B likewise to be substituted by the group Z, defined below, Z denotes a group which confers solubility in water, such as the carboxyl group or sulfo group, one to three of which are bonded to A and/or B, Cu is a copper atom, X denotes an oxygen atom or a carbonyloxy group and is bonded to A in the ortho-position relative to the nitrogen atom, Y represents the vinyl or beta -thiosulfatoethyl group and M denotes a hydrogen atom or the equivalent of a metal. The new copper-complex formazan compounds can be prepared in a manner which is in itself customary, for example by reacting an aromatic hydrazone compound of the general formula: in which A, B, X and Z have the abovementioned meaning, with the diazonium compound of an aromatic amine of the general formula: in which M and Y have the abovementioned meaning, and with an agent which donates copper. The new copper-complex formazan compounds have valuable dyestuff properties and are particularly suitable as fiber-reactive dye-stuffs for dyeing, for example, cellulose fiber materials, wool and synthetic polyamide fibers, on which they give strong reddish-tinged to greenish-tinged blue or clear blue dyeings with good fastness to light and wet processing.

Abstract: Disazo compounds corresponding to the general formula (1) (1) as well as their metal salts, in which D1 denotes the benzene or naphthalene nucleus, which can be further substituted by one or two substituents from the group of fluorine, chlorine, bromine, carboxy, lower alkyl, lower alkoxy and nitro and/or one, two or three sulfo groups, D2 is the benzene or naphthalene nucleus, which is substituted by the substituent X defined below and, in addition to the group -SO2-Y, can be further substituted by one or two substituents from the group of carboxy, lower alkyl and lower alkoxy and/or by one substituent from the group of fluorine, chlorine, bromine and nitro and/or one, two or three sulfo groups, X denotes a fluorine, chlorine or bromine atom, which is necessarily bonded to D2 in ortho-position to the azo group, Y denotes the vinyl, beta -sulfatoethyl, beta -chloroethyl, beta -thiosulfatoethyl or a beta -acyloxyethyl group with the acyl radical of a lower alkanecarboxylic acid or of a benzoic acid or of a benzenesulfonic acid, and a and b each represent the number zero or 1, the sum of (a+b) being equal to 1 or 2. These compounds (1) are very suitable as fiber-reactive dyes for dyeing, for example natural or regenerated cellulose fiber, wool or synthetic polyamide fibers. They give on these materials intense dyeings and prints of good fastness properties, and are distinguished, in particular, by a good stability to copper ions, when used in printing processes.
