Abstract: The dyes of the formula I given in claim 1 are suitable for dyeing furs and in particular leather.They are preferably used in admixture with a blue dye and a red dye for the trichromatic dyeing of leather.

Abstract: A process for the trichromatic dyeing and printing of natural and synthetic polyamide material with dyestuff mixtures. The process employs a red dye together with a blue mixture of dyes and a yellow or orange dye or mixtures thereof.The process is suitable for dyeing natural or synthetic polyamide material from an aqueous liquid or for printing with printing pastes, especially for dyeing from short liquors.

Abstract: The invention relates to a process for the trichromatic dyeing or printing of natural and synthetic polyamide materials with dye mixtures, in which process there is used the dye of the formula ##STR1## wherein R.sub.1 is methyl or ethyl, and R.sub.2 is cyclohexyl or phenyl, together with at least one dye of the formula ##STR2## wherein B.sub.1, B.sub.2 and E.sub.1 are hydrogen, C.sub.1 -C.sub.4 -alkyl or C.sub.1 -C.sub.4 -alkoxy, and X is straight-chain or branched-chain C.sub.1 -C.sub.4 -alkyl, or straight-chain or branched-chain C.sub.2 -C.sub.4 -hydroxyalkyl, and a dye of the formula ##STR3## wherein one Y is hydrogen or methyl, and the other Y is C.sub.2 -C.sub.4 -alkanoylamino or C.sub.2 -C.sub.4 -hydroxyalkylsulfamoyl, or with a mixture of the dyes of the formulae ##STR4## where Y.sub.1 in the formula (4) is C.sub.2 -C.sub.4 -hydroxyalkylsulfamoyl, and Z is hydrogen or methyl, and Y.sub.2 in the formula (5) is C.sub.2 -C.sub.4 -alkanoylamino, Z in the formula (4) being hydrogen when Y.sub.

Abstract: Red monoazo dyestuffs frm diazotised 1-aminobenzene-2-sulphonic acid-N-methyl-N-cyclohexylamide or 1-amino-4-,-5- or -6-methyl-benzene-2-sulphonic acid-N-methyl-N-cyclohexylamide and 2-amino-8-hydroxynaphthalene-6-sulphonic acid are disclosed which are particularly distinguished by their good migration and levelling properties and excellent fastness to light. Said dyestuffs are moreover suitable for obtaining very even combination dyeings together with known blue or yellow acid dyestuffs. These dyestuffs are particularly suited for the dyeing of carpeting, upholstery fabrics and drapery materials.

Abstract: Water-soluble copper, cobalt and chromium complex monoazo compounds of which the metal-free monoazo compound contains as diazo component an aminophenol or aminonaphthol compound subtituted by a fiber-reactive radical of the vinyl sulfone series, the aminophenol possibly being substituted by a lower alkyl, lower alkoxy, nitro, sulfonic acid group, or a chlorine or bromine atom and the naphthol possibly being substituted by a sulfo group, and as coupling component a 6-sulfonaphthol(8) which may be substituted by a sulfo group in the adjacent aromatic nucleus and must be substituted by the monoamide radical of succinic acid, glutaric acid or adipic acid.
