Abstract
"Process for the preparation of complex chromatic reactive azo dyes", characterized in that the mixed chromium complexes 1: 2, which as free acids correspond to the formula ** (See formula) ** where A1 and A2 mean residues of the benzene or naphthalene series in which -O- or - (CO) mO- are in the position or towards the azo radical, B means the remainder of a phenolic or enolic coupling component in which -O- is located adjacent to the azo radical, and where A2 and B do not contain any grouping of formula ** (See formula) ** R means hydrogen or a lower alkyl radical and m and n the figures 0 or 1 are reacted with at least bifunctional reactive components to dyes which, as free acids, correspond to the formula ** (See formula) ** where A1, A2, B, R, m and n have the meaning indicated above and X means an organic residue with at least one reactive radical.
