摘要

1. A chromium complex of the formula see diagramm : EP0141416,P30,F3 in which A is the radical of a dicyclically metallisable azo or azomethine dye, B is the radical of a monoanionic bidentate complexing organic compound which is bonded to the chromium atom via oxygen atoms, L is a colourless monofunctional ligand, X is a halogen-substituted C2-4 alkanoyl reactive radical, a C3-4 alkenoyl reactive radical which can be substituted by halogen, or a reactive radical of the pyrimidine series, the reactive radical X being bonded to the radical A and/or B via a bridge member, Ka is a cation, m is 1, 2, or 3, n is 1 or 2, and the SO3 (cation) Ka group is bonded to the radical A and/or B.
