Abstract
The invention comprises the chromium complexes of azo dyes whic in the acid form are of formula <FORM:0977803/C4-C5/1> wherein A1 and A11 are substituted or unsubstituted o-phenylene or -naphthylene radicals, B1 and B11 are coupling components linked in ortho or vicinal position to D1 or D11, Z1 and Z11 are -O- or -CO- and may be the same or different, D1 and D11 are -O- or -NH- and may be the same or different, m is 1 or 2, X is a -NH-, -NR- or -SO2NH- group wherein R is a C1-C4 alkyl radical, Y is a chlorine or bromine atom and R1 and R2 each represent a hydrogen or chlorine or bromine atom, provided that A1, A11, B1 and B11 ar free from carboxylic acid groups and together contain one sulphonic acid group. The dyes are prepared by the methods described in the parent Specification using the appropriate intermediates. They may be used to colour nitrogenous textile materials, in particular wool, in a variety of shades. The preparation of the dyes is described in examples. Specification 944,717 also is referred to.
