Abstract
Process for the preparation of metal-containing azo dyes, containing in complex form a chlorine atom linked to two different molecules of monoazo dyes, characterized in that a mono-azo dye is reacted together in a molecular ratio of approximately 1: 1. of the formula ** (See formula) ** in which the symbols R, Y and Z, each means a hydrogen atom, or a chlorine atom, or a nitro group, however R and Y represent at the most, simultaneously a nitro group and, R can also be an alkyl or lower molecular alkoxy group and X means a hydrogen or chlorine atom, and a complex chromium compound, which contains linked a complex chromium atom and a molecule of a mono azo dye of the formula ** (See formula) ** in which one X means a sulfonic acid group and the other two mean hydrogen, Y means hydrogen or a nitro group, and Z means a hydrogen or chlorine atom or a nitro group, an alkyl group or lower molecular alkoxy, with the further proviso that Y and Z must be different from each other.
