Abstract:
The invention relates to chromium complexes of the formula ##STR1## in which A is the radical of a dicyclically metallizable azo or azomethine dye, B is the radical of a potentially at least bidentate bianionic complexible organic compound which contains no azo or azomethine group, L is a colorless monofunctional ligand, X is a fibre-reactive radical, Ka is a cation, K is 0 or 1, m is 1, 2 or 3, n is 1 or 2, and the X radical and the SO.sub.3.sup..crclbar. Ka group are each bonded to the radicals A and B, to a process for preparing the chromium complexes of the formula (1), and to a combined preparation and dyeing process.
