Abstract: A compound comprising a disazo chromaphore and an optionally substituted acyl group linked together through a —SO2—NH— group, inks comprising these compounds, ink jet printer cartridges containing these inks and their use in ink jet printing.

Abstract: Described are mixtures of fiber-reactive azo dyes whereby black dyeings, including prints, are obtained on hydroxyl- and/or carboxamido-containing fiber materials, such as cellulose fiber materials, wool and synthetic polyamide fibers. The dye mixtures comprise one or more disazo dyes conforming to the general formula (1), one or more monoazo dyes conforming to the general formula (3), one or more monoazo dyes of the general formula (4) and/or (4a), optionally one or more monoazo dyes (2) and optionally one or more monoazo dyes conforming to the general formula (3a), as described in claim 1.

Abstract: Coloring natural or synthetic fiber material containing hydroxyls or nitrogen is achieved by printing or dyeing the fiber material with a water-soluble disazo dyestuff of the formula ##STR1## wherein R.sup.1 is alkyl, alkoxy or alkoxyethoxy, each having 3-6 carbon atoms, B.sup.1 is the radical of a 1-amino-8-hydroxynaphthalene monosulphonic or disulphonic acid and B.sup.2 is the same as B.sup.1 or another napthyl moiety.

Abstract: The present invention relates to monoazo dyes which dye polyamide material with good light- and wet-fastness and which have the formula ##STR1## in which K is the radical of an amino- or alkoxy-benzene, amino- or alkoxy-naphthalene, naphthol, aminonaphthol, pyrazolone, aminopyrazole, indole, naphthimidazole, diphenylamine, tetrahydroquinoline or acetoacetamide and can be further substituted, R is hydrogen, halogen, C.sub.1-6 -alkyl, trifluoromethyl, carboxyl or a --SO.sub.2 --C.sub.1-6 --alkyl, --SO.sub.2 --R.sub.1, ##STR2## --CO--R.sub.4 group, in which R.sub.1 is a substituted or unsubstituted phenyl- or naphthyl-C.sub.1-4 -alkyl radical, R.sub.2 and R.sub.3 independently of one another are hydrogen or a substituted or unsubstituted C.sub.1-6 -alkyl or C.sub.5-7 -cycloalkyl radical and R.sub.4 is a substituted or unsubstituted phenyl radical, and X is hydrogen, C.sub.1-4 -alkyl, C.sub.1-4 -alkoxy or halogen, and in which R in formula (1) may not be hydrogen or chlorine if the radical --N.dbd.
