Process for the preparation of chromium-containing monoazo dyes containing two monoazoic dye molecules in complex bond with a chromium atom, characterized in that chromium yielding agents are reacted with dyes of the general formula ** (See formula) ** where they mean A benzene radical linked ortho to the hydroxyl group with the azo group containing at least one non-ionogenic, sulfur-free substituent, and B a 1-acylamino-7-hydroxynaphthalene radical free of ionogenic groups linked in position 8 with the azo group in which the acyl group is the radical of a carboxylic or sulfonic acid of the benzene series, to which effect the components are selected in such a way that a radical containing sulfonyl groups is present in the acyl radical of the azocomponent in at least one of both monoazo dyes.
