Abstract
The invention comprises dyes of formula:- <FORM:0876632/IV(c)/1> where one Y is H and the other SO3H, X is H or OAlk and Z is Hlg. The dyes are made by reacting substantially equimolar quantities of a cyanuric halide with the appropriate aminoazo dye. Preferably the alkoxy group has 1-4 C atoms, methoxy and ethoxy groups being particularly preferred. Z is specified as Br or Cl the latter being preferred. The dyes may be used for colouring proteinaceous materials, e.g. wool, silk, leather, polyamides and modified polyacrylonitriles, preferably from dye-baths containing acid-binding agents but are especially of value in colouring cellulosic materials when applied in conjunction with treatment with an acid-binding agent. An example is provided of the preparation of the dyes and their use in dyeing cellulosic fibres in yellow and reddishyellow shades. Specifications 797,946, 819,585, 820,470, 837,953, 838,337, 842,933 and 847,635 also are referred to.
