    Abstract: Uniformly dyed water-swellable cellulosic fibers obtained by dyeing cellulosic fibers in the swollen state with a dye of the formula in which D is the radical of a diazo component; R1 and R2 are optionally substituted alkyl and one of them may also be cyclohexyl, phenyl, methoxyphenyl or ethoxyphenyl and X is hydrogen, chloro, methyl or acylamino, the molecule containing in the radicals R1, R2 and X at least one group: -CO-R3-Y-Ar where R3 is C1 to C3 alkylene; Y is oxygen, sulfur or R4 is hydrogen or C1 to C4 alkyl; and Ar is phenyl or phenyl bearing chloro, bromo, methyl, methoxy, ethoxy, C1 to C4 alkoxycarbonyl or cyano as a substituent.

    Abstract: Reactive dyes which in the form of the free acids correspond to the general formula I where R1 is hydrogen, chlorine, bromine, methyl or hydroxysulfonyl, R2 is chlorine, bromine or phenyl, or is C1-C4-alkoxy which is unsubstituted or substituted by hydroxyl, C1-C4-alkoxy or phenoxy, or is phenoxy or naphthoxy which are unsubstituted or substituted by C1-C10-alkyl and X is fluorine, chlorine or bromine, are exceptionally suitable for dyeing hydroxyl-containing material, e.g. cellulose or leather.

    Abstract: Bis-(4-(1-phenyl-5-hydroxy-1H-pyrazol-4-ylazo)-phenyl) compounds of formula (I) and corresponding mono- or di-copper complexes of formula (II) are new, where R = H, alkyl (optionally substituted by halogen), alkoxy, halogen, NO2, COOH or SO3H; R = H, alkyl, alkoxy, halogen, NO2 or SO3H; R = H, alkyl, halogen or SO3H; R = H, alkyl or halogen; Y = alkyl or COOH; all alkyl moieties have 1-4C; L = SO2NH, CONH or NHCONH (with either terminal bonded to X in the case of (II)); and X = group of formula (X1) or (X2). Preferably R = H, Me, Et, CF3, OMe, OEt, Cl, Br, NO2, COOH or SO3H; R = H, Me, Et, OMe, OEt, Cl, Br, NO2 or SO3H; R = H, Me, Et, Cl, Br or SO3H; R = H, Me, Et, Cl or Br; Y = Me, Et or COOH; L = SO2NH or CONH (both with either terminal bonded to X in the case of (II)). (I) or (II) contains at least one COOH and/or SO3H group.

    Abstract: Reactive dyes which in the form of the free acids correspond to the general formula where A is fluorine, chlorine or bromine, B is hydrogen, chlorine, methyl, methoxy, ethoxy, hydroxysulfonyl or carboxyl, R is carboxyl, C1-C4-alkoxycarbonyl, carbamyl, N-mono- or N,N-di-C1-C4-alkyl- or -hydroxyalkyl-substituted carbamyl, carbopiperidide, carbopyrrolidide or carbomorpholide and R1 is C1-C4-alkyl which is unsubstituted or substituted by cyano, hydroxyl or carboxyl, phenyl which is unsubstituted or substituted by methyl, ethyl, fluorine, chlorine, bromine, amino, trifluoromethyl, methoxy, ethoxy, cyano, phenoxy, acetyl, methylsulfonyl, benzoyl, phenylsulfonyl, acetylamino, nitro, hydroxyl, carboxyl, carbamyl, 2-benzthiazolyl or sulfamyl, or naphthyl which is unsubstituted or substituted by hydroxysulfonyl. The novel compounds are particularly suitable for dyeing cellulose-containing textile materials, polyamides and leather.
