    Abstract: 1. Disazo compounds of the general formula (1) see diagramm : EP0133283,P11,F1 in which D is the phenyl radical or a naphthyl radical, both of which can be substituted by a sulfo group of the formula -SO3 M and furthermore by one or two substituents from the group comprising methyl, ethyl, methoxy, ethoxy, chlorine, bromine and carboxy of the general formula -COOM, and each of which is substituted by one or two groups of the general formula -SO2 -X, in which X represents the vinyl group or a beta-sulfatoethyl group of the general formula -CH2 -CH2 -OSO2 M ; M is a hydrogen atom or an alkali metal ; R is the acyl radical of an aliphatic or aromatic carboxylic acid or of an aliphatic or aromatic sulfonic acid or a radical of the formula (2a) see diagramm : EP0133283,P11,F3 in which R*** is a sulfophenylamino group, the beta-sulfoethylamino group or the N-methyl-beta-sulfoethylamino group, and R**+ represents the hydroxy, methoxy, ethoxy, amino or methylamino group.

    Abstract: It had been found that the dyestuff of the formula (I) is very suitable in a differential dyeing process for the dyeing of polyamide fiber materials at a pH of 2 to 9; the dyestuff possesses a very good differentiating behavior and migrating behavior yielding dyeings of a high degree of evenness while it does not dye accompanying non-polyamide fibers, not even in traces.
