    Abstract: 1,139,310. Anthraquinone dyes. BADISCHE ANILIN- & SODA-FABRIK A.G. 6 May. 1966 [8 May, 1965], No. 20025/66. Heading C4P. The invention comprises anthraquinone dyes of the formula wherein Ar represents a substituted or unsubstituted aryl radical, the radicals R 1 and R 2 represent hydrogen atoms and/or alkyl, aralkyl, cycloalkyl, aryl or heterocyclic radicals which may bear OH, NH 2 , alkoxy or substituted amino groups, or together with the N atom form a heterocyclic ring, and n represents an integer from 1 to 4; with the proviso that groups in which R 1 represents H or a hydroxyalkyl group and R 2 represents H, C 1 to C 6 alkyl or hydroxyalkyl are excluded. They may be obtained by treating an anthraquinone compound of the formula wherein Ar 1 represents an unsubstituted or substituted aryl radical with chlorosulphonic acid or oleum and a halogenating agent and then treating the sulphochloride compound with at least a stoichiometric quantity of a compound of the formula Specified aryl radicals are phenyl, naphthyl and diphenyl radicals. The aryl radicals may bear halogen atoms, alkyl, alkoxy, aryloxy, acyl, hydroxy or acid groups. Examples are given for the production of the dyes. They are useful for dyeing or printing textile materials, and other natural or synthetic materials bright violet shades.

    Abstract: Dye mixtures used for dyeing fur skins black comprise by weight 55 to 74% of a dye having the general formula wherein R1 is a chlorine atom or a methyl, methoxy, amino, acetylamino or benzoylamino group which may contain halogen, methyl or a methoxy group in the phenyl group and R2 is hydrogen, a sulphonic acid or a sulphonamide group, 21 to 36% Acid Orange 7 (sulphonilic acid-->b -naphthol); 3.5 to 9.1% Acid Violet 15 and 1.5 to 3.9% Acid Violet 21 (triphenyl methane dyestuffs).ALSO:Fur skins, e.g. sheep, rabbit and musquash are dyed black using dye mixtures comprising by weight 55 to 74% of a dye having the general formula wherein R1 denotes a chlorine atom or a methyl, methoxy, amino, acetylamino, or benzoylamino group which may be substituted in the phenyl group by halogen, methyl or methoxy, and R2 is hydrogen, a sulphonic acid or sulphonamide group, 21 to 36% Acid Orange 7; 3.5 to 9.1% Acid Violet 15 and 1.5 to 3.9% Acid Violet 21.

    Abstract: The invention comprises a dye mixture having a content of 2 to 98 mole per cent of an anthraquinone dye having the formula wherein Ar represents a substituted or unsubstituted aryl radical, the radicals R1 and R2 represent hydrogen atoms and/or alkyl, aralkyl cycloalkyl, aryl or heterocyclic radicals which may bear OH, NH2, alkoxy or substituted amino groups, or together with the N atom form a heterocyclic ring, n represents an integer from 1 to 4 and R represents a halogen atom, and 98 to 2 mole per cent of an anthraquinone dye having the general Formula I in which R represents the radical The mixtures may be obtained by mixing the individual dyes or by treating an appropriate mixture of compounds of the formulae wherein Ar1 represents a substituted or unsubstituted aryl radical, with chlorosulphonic acid or oleum and a halogenating agent and then treating the sulphochloride compounds with at least a stoichiometric quantity of a compound of the formula Specified aryl radicals are pheny, naphthyl and diphenyl radicals. The aryl radicals may bear halogen atoms, alkyl, alkoxy, aryloxy, carboxylic acyl, hydroxy and acid groups. Examples are given for the production of the dyestuff mixtures. They are useful for dyeing or printing textile materials, and other natural or synthetic materials bright violet shades.

    Abstract: The invention comprises anthraquinone dyes of the formula wherein X is a linear or branched 1-5 C aliphatic group, Y is -O-, -S-, -SO2-or -NR- (R being H or an aliphatic or aromatic radical), Z is a linear or branched 1-6 C possibly substituted aliphatic group or a single bond. A is an unsubstituted or substituted aromatic group, preferably consisting of one or two six-membered rings, m is 1, 2 or 3, n is 1 or 2, R1 and R2 are each H or unsubstituted or substituted alkyl, aralkyl, aryl, cycloalkyl or heterocyclic radicals or together with the N atom form a heterocylic ring and wherein the anthraquinone radical may bear substituents. The dyes may be prepared by converting suitable anthraquinones with chloro-sulphonic acid to sulphochlorides of the formula and then allowing NH3 or a 10 or 10 amine to. act upon the sulphochlorides. The dyes are suitable for colouring fibres or films of synthetic polyamides, polyurethanes, polyesters, wool, silk, cellulose acetates, natural and regenerated cellolose or may be employed as pigments. Examples are given.ALSO:Materials of cotton or polyamide are dyed by the process of Specification 923, 162 using dyes of the formula (I) where X is a linear or branched 1-5C aliphatic, Y is -O-, -S-, -SO2- or -NR- (R being H, aliphatic or aromatic), Z is linear branched 1-6C possibly substituted aliphatic or a single bond, A is possibly substituted aromatic, m is 1, 2 or 3, n is 1 or 2, R1 and R2 are each H or possibly substituted alkyl, aralkyl, aryl, cycloalkyl or heterocyclic or together with the N form a heterocyclic ring and wherein the anthraquinone radical may bear substituents.
