    Abstract: Compounds according to the general formula DNN[(4)E(1)]NN +TR in which: D is phenyl, optionally substituted by sulfo, carboxy, alkyl, alkoxy, alkanoylamino and/or chlorine, at least by sulfo or carboxy, or is a sulfosubstituted naphthyl; E is 1,4-phenylene, substituted by alkyl, alkoxy, alkanoylamino, ureido and/or chlorine, or is 1,4-naphthylene optionally substituted by sulfo; K is 1,4-phenylene, substituted by alkyl, alkoxy, alkanoylamino, ureido and/or chlorine, or is a 1,4-naphthylene optionally substituted by sulfo; A is a direct bond or is methylene or is a bivalent amino, alkylamino or ( beta -cyanoethyl)-amino group; Y is vinyl or beta -chloroethyl. These compounds are fiber-reactive and have dyestuff properties and dye hydroxy-and/or carboxamido-containing material, in particular fiber material such as wool and, in particular cellulose, in strong color-fast shades.

    Abstract: Water-soluble disazo compounds of the formula in which D is a benzene ring or a naphthalene ring which can both be substituted by substituents from the group consisting of chlorine, bromine, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, carboxy and sulfo, X is the vinyl group or a beta -sulfatoethyl group, R is a beta -sulfatoethylsulfonyl, 3-( beta -chloroethylsulfonyl)-benzoyl, 4-( beta -chloroethylsulfonyl)-benzoyl, 3-( beta -chloroethylsulfonylmethyl)-benzoyl, 4-( beta -chloroethylsulfonylmethyl)-benzoyl,4-( beta -chloroethylsulfonyl)-cinnamoyl, 3-(N-methyl-N- beta chloroethylsulfonyl)-aminobenzoyl or 4-(N-methyl-N- beta -chloroethylsulfonyl)-aminobenzoyl group, m is the number 1 or 2 and M denotes a hydrogen atom or an alkali metal. The disazo compounds are suitable for use as dyes having fiber-reactive properties for dyeing hydroxy- and/or carboxamido-containing fiber material, such as in particular cellulose fiber materials and polyamide fiber materials. These disazo compounds have good solubility and stability in printed pastes and dyebaths; they exhibit a high color strength and a good color buildup; and they produce, in high degrees of fixation, navy to black dyeings and prints with good fastness to, inter alia, light, wash, seawater, chlorinated water, acid, and alkali, and these dyeings and prints have stability toward copper ions.

    Abstract: Water-soluble azo compounds, having fiber-reactive properties and yielding (for instance, on cellulose fiber materials) deep and fast dyeings and prints, of the formula in which D is phenylene which can be substituted by one or two subtituents from the group consisting of lower alkyl, lower alkoxy, hydroxy, lower alkanoylamino, benzoylamino, benzoylamino substituted by lower alkyl, lower alkoxy, chlorine and/or sulfo, chlorine, bromine, fluorine and carboxy and/or by a nitro group and/or by a further group of the formula Y-SO2-(CH2)n- in which Y has the meaning given below and n here is 1 or 2, or D is naphthylene which can be substituted by one or two substituents from the group consisting of lower alkyl, lower alkoxy, hydroxy, lower alkanoylamine, benzoylamino, benzoylamino substituted by lower alkyl, lower alkoxy, chlorine and/or sulfo, chlorine, bromine, fluorine, carboxy and sulfo and/or by a nitro group, or D is the benzothiazol-2-yl radical which contains the indicated group Y-SO2-(CH2)n- in the carbocyclic ring and can be further substituted in this benzene nucleus by a substituent from the group consisting of lower alkyl, lower alkoxy, hydroxy, lower alkanoylamino, benzoylamino, benzoylamino substituted by lower alkyl, lower alkoxy, chlorine and/or sulfo, nitro, chlorine, bromine and sulfo, M is hydrogen or an equivalent of a metal, R is the acyl group of an optionally substituted lower alkanoic acid, lower alkenoic acid, aromatic carboxylic acid, lower alkanesulfonic acid, aromatic sulfonic acid, carbamic acid or lower alkenesulfonic acid, Y is the vinyl group or a group -CH2-CH2-Z in which Z represents a radical which can be eliminated under alkaline conditions, or the hydroxy group, and n is zero, 1 or 2.

    Abstract: Water-soluble compounds having fiber-reactive dye properties of the general formula in which A is an alkylene of 2 to 6 carbon atoms or a phenylene which can be substituted by 1 or 2 substituents, or is a radical of the formula in which W is a direct bond or a bridge member and the R' and R* each denote hydrogen, chlorine, methyl, methoxy, ethoxy, carboxy or sulfo; B is chlorine or fluorine; R is hydrogen, chlorine, an alkyl of 1 to 4 carbon atoms or an alkoxy of 1 to 4 carbon atoms; M is hydrogen or an alkali metal; n stands for the number zero, 1 or 2, K is a radical of the formula +TR in which D is phenylene which can be substituted by chlorine, bromine, alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, carboxy or sulfo, or is naphthalene with optionally 1 or 2 sulfo groups, R1 denotes hydrogen, chlorine, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms, R2 is hydrogen or alkyl of 1 to 4 carbon atoms, G is carboxy, methyl or carbalkoxy of 2 to 5 carbon atoms, Y denotes vinyl, beta -sulfatoethyl, beta -phosphatoethyl, beta -thiosulfatoethyl or beta -chloroethyl, Z is the alpha - or beta -bromoacryloyl or beta -chloropropionyl or a radical of the formula with B, D and Y of the abovementioned meanings. The novel dyes are suitable for dyeing hydroxyl- and/or carbamoyl-containing material; on hydroxyl-containing material, such as cellulose fibers, they become fixed not only in the alkaline but also in the weakly acid to neutral range, so that they can be used together with disperse dyes for dyeing blend material composed of cellullose and polyester fibers by the dyeing methods for disperse dyes.
