u, v = NH 2 oder OH und u ≠ v, Z, Y = NO 2 oder SO 3 H und Z ≠ Y sowie m = 1 oder 2. New disazoreactive dyes are provided which correspond to the following general formula: where D = residue of a reactive group-containing diazo component of the benzene or naphthalene series, u, v = NH 2 or OH and u ≠ v, Z, Y = NO 2 or SO 3 H and Z ≠ Y as well m = 1 or 2. n n n The new dyes are outstandingly suitable for dyeing and printing hydroxyl and / or amide group-containing materials. |
