<p>1:2 Chromium complex dyes of the formula (1) wherein A is the radical of a diazo component of the benzene or naphthalene class which carries the complex forming group X in ortho-position to the azo group, B is the radical of a coupling component which couples in ortho-position to the oxy group, D is the radical of an amine of the benzene or naphthalene class which carries the complex-forming group in ortho-position to the azo group, X is an oxygen atom or a-CO-O- group, Ar is an aromatic carbocyclic radical. Ar' and Ar" are aromatic carbocyclic or heterocyclic radicals. q is an integer from 0 to 5, n is an integer from 1 to 3, m is an integer from 0 to 2 and p is 0 or 1, but the sum of n + m may be at most 3, and wherein the benzene ring can carry a further fused benzene ring or can be substituted by halogen. nitro, alkyl or alkoxy, and K+ is a cation.</p> |
