Process for obtaining azo dyes of mixed chromium complex, characterized in that on a mixture of monoazo dyes of formulas ** (See formula) ** where A and B represent traces of diazo compounds, in which the substituents X and X1 are in the position or in relation to the azo group, X and X1 metal complexing groups or by such substituents which under the metallization conditions are transformed in metal complex forming groups, R represents a group of alkylsulfonyl or arylsulfonyl and R1 means an acyl residue other than R, optionally in a mixture with other metallizable dyes, chromium-binding means are allowed to react in such a way that compounds are formed of chromium complex 2: 1, or by the fact that the chromium complex compound 1: 1 of one of the two dyes mentioned is reacted with the other metal-free dye to the chromium complex compound 2: 1.
