    Abstract: 1. A process for preparing mixtures of 1:2-cobalt complex and 1:2-chromium complex azo dyestuffs of the general formula (1) see diagramm : EP0103165,P10,F1 in which Me is a cobalt atom or a chromium atom, R represents a hydrogen atom, the methyl group or the methoxy group, M denotes a hydrogen atom or an alkali metal atom or the equivalent of an alkaline earth metal atom, and the group of the formula -SO2 -CH2 -CH2 -OSO3 M is bonded to the benzene nucleus in meta- or para-position relative to the NH-group, in a molar mixing ratio of 1:5 to 5:1, characterized by that, in a one-vessel process and without intermediate isolation of the process intermediates, first of all to diazotize 4-nitro-2-aminophenol and couple with 1-amino-8-hydroxy-naphthalene-3,6-disulfonic acid to give an azo compound of the general formula (3) see diagramm : EP0103165,P10,F2 in which M has the abovementioned meaning, to convert this azo compound without intermediate isolation by reaction with an equivalent amount of cobalt- and chromium donating agents for which the molar ratio between cobalt and chromium is within the range from 5:1 to 1:5, into a mixture of 1:2-cobalt complex and 1:2-chromium complex azo compounds of the general formula (4) see diagramm : EP0103165,P11,F3 in which Me and M have the abovementioned meanings, and then to react this mixture of metal complex azo compounds of the general formula (4) without intermediate isolation with a compound of the general formula (5) see diagramm : EP0103165,P11,F4 in which M and R have the abovementioned meanings and the beta-sulfatoethylsulfonyl group is bonded to the benzene nucleus in meta- or para-position relative to the NH-group, to yield the mixture, in accordance with the invention, of 1:2-chromium complex azo dyestuffs of the general formula (1).
