Abstract
The invention comprises reactive azo dyes which contain at least two sulphonic acid groups and are of formula <FORM:1002232/C4-C5/1> wherein R1, R2 and R3 are benzene or naphthalene residues, m is 1 or 2, Y is a benzene residue bound to R3 through a triazole ring and X is the residue of b -chloropropionic, acrylic or a chloroacrylic acid or a halogenated heterocyclic residue containing 2 or 3 ring nitrogen atoms. The dyes may be prepared by triazolizing an amino-azo dye of formula <FORM:1002232/C4-C5/2> wherein Z is a benzene residue having an -NH2 group in o-position to the azo bridge and condensing the aminotriazole dye obtained with e.g. beta-chloropropionyl chloride, acrylic and chloroacrylic acid halides, tri- and tetrachloropyrimidine and preferably, cyanuric chloride or bromide or monocondensation products thereof. The traizolation and condensation steps may be reversed. The dyes may be used to colour cellulose fibres from an alkaline dyebath in yellow shades. Examples describe the preparation of the dyes and their use in dyeing. Specification 838,337 is referred to.
