    Abstract: The invention comprises water-soluble azo dyes of the formula wherein X is H, alkyl, alkoxy or acylamino, Y is H, alkyl, alkoxy or SO3H, R is H, alkyl or substituted alkyl and n is 1 or 2. They may be obtained by reacting an azo dye of the formula with diketene with acetoacetylation of the amino group. Examples are given for the production of the dyes. They are useful for dyeing or printing natural or synthetic polyamide textile materials.

    Abstract: The invention comprises compositions and a process for dyeing, printing and/or optical brightening of textile materials in which the material is treated if necessary at elevated temperatures in the presence of an alkaline reacting agent with a dye or optical brightener which has one or more reactive hydrogen atoms attached preferably by nitrogen, oxygen, or sulphur, or which is capable of forming one or more such hydrogen atoms during the process, and with an uncoloured non-brightening polyfunctional compound which contains two or more different reactive substituents which are acryloyl radicals, a -haloacryloyl radicals, chloromethylbenzoyl radicals, 3, 4-dichlorobutane-(2) radicals, 4-chlorobutine-(2) radicals or propionyl radicals, bearing b -position ether groups, thioether groups, sulphone groups, or hydroxyl or mercapto groups esterified with strong oxyacids, and which are preferably attached by nitrogen, and/or the ethylenimine radical which is preferably attached by sulphur, and/or the vinylsulphone radical which is preferably attached by nitrogen or carbon, and/or substituents which are capable of being converted into such radicals during the process. The dyes used may be water soluble or insoluble, many types are specified, and inorganic and organic alkaline reagents may be used. Fabrics treated include, native or regenerated cellulose, cellulose acetate, polyacrylonitrile and its copolymers, polyesters, wool, silk or linear polyamides. Fluorescent brighteners include those of the stilbene, benzimidazole, benzoaxazole and benzothiazole seroes. Specifications 520,199, 805,548, 811,221, 827,568, 831,371, 867,546, 898,318, 900,764, 908,301, 915,457, 916,532, 917,764, 919,179, 924,258 and 942,766 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.
