Abstract

Process for the preparation of metal-containing azo dyes, which contain a chromium atom bound in complex form in two different monoazo dye molecules, characterized in that they are reacted with each other in a molecular ratio of approximately 1: 1, a metalizable monoazo dye , which contains a single sulfonic acid group and which is not free of carboxylic acid groups in a position neighboring the azo group, and of the formula ** (See formula) ** in which D means the radical of a diazo component, preferably of the benzene series, linked to the azo bridge in a position adjacent to the group ** (See formula) ** A means the radical of a coupling component, which is linked to the azo bridge in a position adjacent to an enolized or enolizable keto group or to an amino or hydroxyl group, and n means a positive integer of value 2 at the most, and a chromium complex compound containing a complex chromium atom linked to a monoazoic dye molecule of the formula ** (See formula) ** in which one of the symbols X, Y and Z means hydrogen, and each of the others a hydrogen or halogen atom, a nitro group or an alkyl or lower molecular weight alkoxy group.
