    Abstract: In a process for dyeing and/or printing textile material, the material is treated with uncoloured polyfunctional compounds which are capable under alkaline conditions of effecting wash-fast fixation of dyes containing reactive hydrogen atoms on cellulose and with a dye containing one or more reactive hydrogen atoms preferably attached via N, O or S or capable of forming same during process and containing, preferably attached via N, at least one acryloyl or vinyl sulphone radical or a propionyl radical bearing in the b -position an -OH group esterified by a strong oxyacid or an ether, thioether or sulphone group, or bearing a b -hydroxethyl radical esterified by a strong oxyacid, or at least one b -haloethylsulphonamide radical or at least one radical having the grouping -N=C-Cl, or capable of forming such radicals during the process. The uncoloured polyfunctional compounds may be compounds which contain two or more Ch2=CH-CO- groups attached via N or two or more CH2=CH-SO2- groups attached via N or O or at least three ethylenimino groups attached via C or P or which are capable of forming such groups during the process as well as heterocyclic compounds containing at least three epoxy groups. The process may be applied to the textile materials of natural and regenerated cellulose, wool, silk, linear polyamides, acrylonitrile polymers and copolymers, cellulose acetate and aromatic polyesters. A number of suitable reactive dyestuffs are listed which may be water-insoluble or preferably water-soluble and come from the azo, anthraquinone and phthalocyanine series. The alkaline agents may be alkali metal hydroxides, carbonates, bicarbonate, acetate, disodium or trisodium phosphate, pyridine, benzyltrimethylammonium hydroxide or mixtures thereof. The dye, polyfunctional compound and alkali may be applied to the material in any sequence but preferably simultaneously, if desired together with dispersing agents and vinal auxiliaries. The polyfunctional compounds may be employed in aqueous solution or dispersion or as solutions in water-miscible organic solvents. Fixation may be achieved at 15-30 DEG C. but preferably by steaming or day heating at 70-150 DEG C. Examples are given. Specifications 867,546, 885,814, 900,372 and 915,457 are referred to.

    Abstract: The invention comprises dyes of formula wherein B is a CH2=CH-CO- or A-CH2-CH2-CO residue and A is the radical of an organic textile dye with the proviso that the said radical contains at least one sulphonic acid group directly attached to the anthraquinone nucleus when A is the radical of an anthraquinone dye. The dyes are prepared by reacting appropriate dyes or compounds capable of coupling or diazotizable aromatic or heterocyclic amines or N-formyl derivatives thereof, which contain in the molecule at least one reactive hydrogen atom, preferably linked via an oxygen, nitrogen or sulphur atom, or a methylene ether nitrogen or sulphur atom, or a methylene ether or methylene ester group with hexahydro-1,3,5-triacryloyl-s-triazine or with compounds convertible thereto under the reaction conditions, the reaction being conducted in an alkaline aqueous and/or organic solution or suspension at temperatures up to 200 DEG C. The diazotizable amines and coupling components so obtained, if necessary after removal of the N-formyl group by hydrolysis, are converted into azo dyes by the usual coupling procedures. The dyes are used as reactive dyes in the dyeing and printing of cellulose, natural and synthetic polyamide, polyvinyl alcohol, leather, paper and polyacrylonitrile materials. The preparation of dyes of the monoazo, metallized azo, phthalocyanine, xanthene and anthraquinone series is specified in examples.

    Abstract: The invention comprises azo dyes containing, attached by way of a nitrogen atom, the radical of the formula in which R1 denotes a hydrogen atom or an alkyl, cycloalkyl, aralkyl or aryl group, R2 denotes a hydrogen atom or an alkyl, cycloalkyl, aralkyl or aryl group, E denotes a halogen atom, a quaternary ammonium group or an ester group the acid radical of which is derived from polybasic mineral acid or an organic derivative thereof and Y denotes a group of the general formula in which A denotes an alkylene radical or a substituted alkylene radical, Z1 denotes a hydrogen atom, a halogen atom or an alkyl group and Z2 denotes a hydrogen atom, a halogen atom or an alkyl group and processes for the preparation thereof wherein (a) an azo dye or an intermediate suitable for the production of an azo dye, which contains one or more reactive hydrogen atoms attached by way of nitrogen is reacted with an isocyanate of the general formula or with a corresponding compound capable of being converted into the isocyanate under the reaction conditions and, when a dye intermediate has been used completing the conversion of the reaction product to the azo dye, or (b) an azo dye or an intermediate suitable for the production of an azo dye, which contains one or more reactive hydrogen atoms attached by way of nitrogen, is reacted with an isocyanate of the general formula in which R1, R2 have the meanings given above, X denotes a halogen atom and X1 denotes a halogen atom or an OH group protected by an acyl radical capable of being split-off or with a corresponding compound capable of being converted into the isocyanate under the reaction conditions, the radical X1 in the reaction product is converted into a quaternary ammonium group when a halogen atom or into an ester group of which the acid radical is derived from a polybasic mineral acid or an organic derivative thereof when an OH group and, when a dye intermediate has been used the conversion of the reaction product to the azo dye is completed. Examples of compounds capable of being converted into isocyanates are carbamic acid halides, phenyl-carbamic acid esters and carboxylic acid azides. Among the isocyanates specified for use in the process are 1-chlorobut-2-ine-4-isocyanate and 1,2-dichloro-but-2-ene-4-isocyanate. The reactive hydrogen in the starting materials may be present in primary or secondary alkyl-amino, arylamino, alkyl- and arylhydrazino groups, hydroxyl-amino, carboxylic acid amide and amidine or hydrazide groups. Cyanamide, urethane, urea, guanidine or sulphonamide groupings may be present where suitable. Acylatable NH groups may also form part of a heterocyclic ring combined with the initial materials as e.g. in pyrrolidine, piperidine, piperazine, pyrrolidone, caprolactan and succinimide. The dyes are suitable for dyeing or printing wool, silk, polyamides, polyurethanes, cellulose or regenerated cellulose and leather with the addition of basic agents. Representative of specific dyes described are those obtained by coupling diazotized N-(41-aminophenyl)-N1 - (1 - chlorobut - 2 - inyl - 4) - urea or diazotized p - amino - sulphanilyl - N1 - dichlorobutenylurea with 1-naphthol-4-sulphonic acid or by reacting chlorobutinyl isocyanate with the dye obtained by coupling p-acetylamino-benzene diazonium chloride with p-cresol and splitting off the acetyl group.

    Abstract: The invention comprises water-soluble anthraquinone dyes of the formula A-(NHCOCH2-CH2-OX)n where A is an anthraquinone dye radical, X is hydrogen or the radical of a carboxylic acid, of sulphuric acid or phosphoric acid and n is 1 or 2, and in particular dyes of the formula where Y is hydrogen or a sulphonic acid group, Z is a direct linkage or one of the radicals -CH2CH2-NH-, and X has the meaning given above. The dyes are made by reacting an anthraquinone of the formula A1-(NH2)n where A1 is an anthraquinone dye radical and n is as above, with a compound of the formula Cl-CO-CH2CH2-OR or by reacting an anthraquinone derivative containing sulphonic acid halide groups with aromatic or heterocyclic amines containing beta-hydroxypropionic acid amide groups or esterified beta-hydroxypropionic acid amide groups. When the products contain carboxylic acid ester groups they may be hydrolysed to the hydroxy derivatives which may then be exterified with a carboxylic acid or sulphuric or phosphoric acid. Examples are given. The dyes dye and print textile materials and shaped articles of wool, silk, synthetic linear polyamides and polyurethanes, cellulose and leather.
