ABSTRACT:
The invention relates to chromium complexes of the formula ##STR1## in which B is the radical of a bidentate bianionic compound, L is H.sub.2 O, NH.sub.3, alkanol, alkylamine, dialkylamine, trialkylamine or pyridine, D is a benzene or naphthalene diazo component, Y is the nitrogen atom or the CH group, K is a coupling component, R is hydrogen, alkyl or phenyl, X is a fibre-reactive group,Ka is a cation, m is 1, 2 or 3, n is 1 or 2 and k is 0 or 1.
These chromium complexes are suitable for dyeing nitrogen-containing or hydroxy-containing materials and they produce level dyeings having good all-round fastness properties.
