    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: 1387728 Preparation of azo dyes containing cyano groups BASF AG 12 July 1972 [13 July 1971] 32541/72 Heading C4P Monoazo dyes free from water-solubilizing groups of formula NC-A-N=N-X wherein the CN group is ortho to -N=N-, A is a substituted phenyl or benzisothiazolyl group and X is an N-substituted para-aminophenyl radical are prepared by reacting the corresponding dyes containing Br in place of CN with CuCN or substances which form it under the reaction conditions in water at an elevated temperature. The dyes are used to colour polyester fibres in green, blue and violet shades. Specification 1,314,538 is referred to.

    Abstract: Acetalized azo dyes are prepared by diazotizing an amine, coupling with a hydroxyalkyl-containing coupling component and subsequently reacting with a vinyl ether in a process which comprises carrying out the coupling reaction in a two-phase reaction mixture comprising water and an aromatic hydrocarbon, subsequently separating off the aqueous phase and reacting the azo dye, which is present in the organic phase, without intermediate isolation, with a vinyl ether in the presence of a polybasic carboxylic acid as catalyst.
