Abstract: Mixtures of dyes of the formula I I where X is chlorine or bromine, Z is hydrogen, methyl, ethyl, C1-C4-alkoxy or acetylamino, R is C1-C4-alkyl, R1 and R2 independently of one another are each allyl or methallyl or are each C1-C6-alkyl which is unsubstituted or substituted by hydroxyl, C1-C4-alkoxy or alkanoyloxy, or R1 and R2 together with the nitrogen atom are morpholino or tetra-, penta- or hexamethyleneimino, and one of the radicals R1 and R2 may furthermore be hydrogen.

Abstract: The invention relates to the use of dyes of the general formula I in which D is the radical of a diazo component of the aniline or heterocyclic series, A is an alkylene radical, R is optionally substituted alkyl, alkenyl, aralkyl or aryl or dialkylamino, R is optionally substituted alkyl, cycloalkyl, alkenyl, aralkyl or aryl and B is hydrogen, fluorine, chlorine, bromine, methyl, ethyl, methoxy, ethoxy or phenoxy, for the preparation of alkaline-dischargeable prints and dyeings.

Abstract: The invention relates to a process for protecting reduction-sensitive disperse (dispersion) dyes from reduction in the course of dyeing and/or printing, which is characterised in that the dyebaths or print pastes are admixed with compounds of the formula I where R is fluorine, chlorine or bromine, R , R , R and R are independently of each other hydrogen, C1-C4-alkyl, C1-C4-alkoxy, phenoxy, C1-C4-alkylsulphonyl, arylsulphonyl, arylsulphonyloxy, aryloxysulphonyl, hydroxyl, C1-C4-alkoxycarbonyl, C1-C4-alkylcarbonyloxy, C1-C4-alkylcarbonyl, phenylcarbonyl, amino, C1-C4-alkylcarbonylamino, fluorine, chlorine, bromine or nitro, X is -SO2-, -SO2O-, -SO2NH- or , and n is 1 or 2.

Abstract: The use of azo dyes of formula (I) for transfer printing is new. In (I), R is H or methyl; R1 is H or 1-4C alkyl and R2 is 1-4C alkyl. Also new are auxiliary carriers for transfer printing which contain (I). (I) are esp. useful for polyester, giving prints of very good fastness to light and wet treatments. In an example, a paper was flexographically printed with an ink comprising 20 pts. (I; R is H; R1 and R2 both methyl); 5 pts. ethylcellulose, 70 pts. ethanol, 20 pts. ethyl acetate and 5 pts. ethyl glycol, then dried. The printed side of the paper was placed on a polyester material and run through a calander for 30 sec. at 210 deg. C. The dye was transferred, giving a reddish-blue print on a white background.

Abstract: The modification (I) of the dyestuff of formula: has an x-ray diffraction diagram showing lines of strong intensity at 9.1 and 25.5 degrees, of medium intensity at 16.1, 17.1, 17.9, 20.1, 20.8, and 27.1 degrees and of weak intensity at 4.8, 11.2, 14.4 and 23.7 degrees at a diffraction angle of 2 H. (I) is dispersion-stable, unlike the alpha-modification (II), and does not flocculate out of aq. medium after prolonged exposure to high temp. It is prepd. by heating (II), opt. in water and/or water-sol. org. solvent.

Abstract: Protection of dispersion dyestuffs (I), which are sensitive to redn., from redn. dyring dyeing and/or printing is effected by adding haloquinone (derivs.) (II) to the dyebath or printing ink. (II) pref. have the formula (IIa). In (IIa) X is F, Cl or Br, Y is F, Cl, Br, OH or CN, Chloranil is esp. suitable. (I) are useful for dyeing and printing cellulose acetate, polyamide and esp. polyester fibres and their mixts. with cellulose and wool. (II) are widely applicable and compatible with dyeing media.
