    Abstract: New water soluble reactive dyestuffs are mono- or bis-(2-substd. -4-cyanamido-s-triazin-6 -ylamino) dyestuff derivs. of formula (I), F = the radical of a mono- or poly- or metal complex azo, anthraquinone, phthaocyanine, azomethin, dioxazine, phenazine, stilbene, triphenylmethane, xanthane, thioxanthone, nitroaryl, naphto or pyerenequinone or perylenetetracarbimide dyestuff, Rx = H, or 1-4C alkyl (opt. substd. by halgoen, OH, CN, 1-4C alkoxy, 2-5C alkoxycarbonyl, COOH, sulphamoyl, SO3H, or OSO3H), n = 2 or pref. 1, Q = a substd. amino gp. of formula (IIa) or (IIb), H, 1-4C alkyl (opt. substd. cyclohexyl, or phenyl (opt. substd. W = (substd) arylene, or alkylene-arylene or arylene or alkylene-arylene -alkylene or arylene-alkylene-arylene in which teh alkylene gps. have 1-8C are opt. substd. and may contain hetero gp(s) the arylene gps. are (substd.) phenylene or naphthylene gps. and the alkylene and arylene pts. in the combined arylene/alkylene gps. may each be sepd. by one hetero gp. Y = vinyl, beta-(thio)sulphato, beta-phosphatoethyl, beta-(2-5C alkanoyloxy), beta-benzoyloxy, beta-(sulphobenzoyloxy) beta-(p-toluenesulphonyloxy) or beta- haloethyl, Z = 1 or 2, A = O or 1, B = 1 or 2, A + B = 2, if B = 2, the -W-(SO2-Y)k gps. may be the same or differetn, X with the N atoms = the bivalent radical of 1 or 2 1-5C alkylene gps. and opt. 1 or 2 hetero gps. alk = a-4C alkylene. The prepn. of (I) is claimed (see below). USE/ADVANTAGE - (I) are claimed for dyeing (including printing) material esp. fibre material, contg. OH and/or carbonamido gps. (I) are esp. used for dyeing cotton and also useful with wool, silk and mixed fabrics contg. these. High colour strength is obtd. and the dyeing is fast, build-up good and the deg. of fixing high.

    Abstract: Water-soluble disazo compounds having useful fiber-reactive dye properties, which conform to the general formula (1) defined hereinafter and dye carboxamido- and/or hydroxy-containing materials in fast shades. Fast dyeings on cellulose fiber materials can also be obtained in a weakly acid to neutral pH range, for example together with disperse dyes for dyeing a polyester fiber portion. (1) in which: A is phenylene which may be substituted by methyl, ethyl, methoxy, chlorine or sulfo, or is a radical of the formula in which G is a direct bond or a group of the formula -CH=CH- or -NH-CO-NH- and R1 and R2 are each independently of the other hydrogen, sulfo, methyl, ethyl, methoxy or ethoxy; D is phenylene which may be substituted by methyl, ethyl, methoxy, ethoxy, sulfo, carboxy, chlorine or bromine, or is naphthalene which may be substituted by sulfo or is a group of the formula and K, as a radical of a coupling component, is a radical of the formula in which M is hydrogen or an alkali metal and Ro is hydrogen or sulfo and the free azo-bond in the amino-naphthol radical is ortho to the hydroxy group, R* is hydrogen, methyl or ethyl and the benzene nucleus a can be substituted by methyl, ethyl, methoxy, ethoxy lower alkanoylamino, benzoylamino, ureido or chlorine; X is vinyl, beta -sulfatoethyl or beta -chloroethyl; R is carboxy or carbamoyl.

    Abstract: Water-soluble disazo compounds conforming to the general formula (1) (1) and their 1:1 copper complex compounds which possess useful fiber-reactive dye properties and are capable of dyeing carboxamido- and/or hydroxy-containing materials, in particular cellulose fibers, in fast shades; wherein: D1 and D2 are each a phenylene, which may be substituted, or a naphthylene optionally substituted by sulfo; in the case of the copper complex compounds the ortho-position in D1 or D2 or in both being substituted by an oxy group complex-bonded to the copper, or D1 is a radical of the formula (2a), (2b) or (2c) (2a) (2b) (2c) or D2 is a radical which is the reverse of formulas (2a), (2b) or (2c), in which R1 and R2 are each independently of the other hydrogen, nitro, sulfo, methyl, ethyl, methoxy or ethoxy; K1 is a radical of the formula (3a), (3b) or (3c) (3a) (3b) (3c) and K2 is a radical which is the reverse of the formulas (3a); (3b) or (3c) in which M is hydrogen or an alkali metal and R* is hydrogen, methyl or ethyl, where in the case of the copper complex compounds the naphtholic hydroxy groups are complex bonded to the copper atom; X is vinyl, beta -sulfatoethyl or beta -chloroethyl; R is carboxy or carbamoyl.
