Abstract
The invention comprises complex metal dyes which contain one atom of chromium bound to two molecules of different metallizable monoazo dyes one of which is of formula:- <FORM:879523/IV(c)/1> where X is a metallizable substituent and Z is H, Hlg, or a sulphonamide, alkoxy or carboalkoxyamino radical and A may be substituted with groups such as sulphonamide and dialkyl amide, alkoxy and/or alkyl groups but is free from sulphonic and carboxylic acid groups (apart from X) and of which the other dye is free from sulphonic and carboxylic acid groups except in #s-position to the azo group. The dyes are made by treating a 1, 1-chromium complex of a dye of the above formula with an equimolar quantity of the second dye. The second dye may contain substituents such as halogen, sulphone, alkyl, alkoxy, nitro, acylamino and sulphonamido groups. The dyes are used especially on nitrogenous textile materials, e.g. leather, synthetic polyamides and polyurethanes and wool which they dye in blue, grey, black, brown and green shades from a neutral to weak acid bath. Examples are provided of the preparation of the dyes and c their use in colouring processes. Specifications 745,479 and 766,554 are referred to.
