Abstract

The invention comprises disazo dyes of formula :- <FORM:0864227/IV(c)/1> wherein R1 is an aromatic residue, advantageously of the benzene or naphthalene series, containing a sulphonic acid group, R2 is a benzene or naphthalene residue and R3 is a p-phenylene residue free from water-solubilizing groups. The dyes may be prepared by condensation of 1 mol of cyanuric chloride with 1 mol of an aminodisazo dye of formula: R1-N=N-R2-N=N-R3-NH2. Components used in the preparation of the intermediate aminoazo dyes and methods of preparation are specified. The dyes give yellow, orange, red and brown shades on cotton. In examples the following aminodisazo dyes are condensed with cyanuric chloride:-4-amino - 1 : 11-azobenzene - 4 : 41-disulphonic acid --> m-toluidineor p-xylidine; 2-aminonaphthalene-4 : 8-disulphonic acid --> m-toluidine -->, 1-amino-2 --> methoxy-5-methyl-benzene; 2-aminonaphthalene-4 : 8-disulphonic acid --> o-toluidine, --> o-toluidine; 1-aminobenzene-3-sulphonic acid, --> 1-amino-naphthalene-6-sulphonic acid, --> aniline; the monoazo dye 4-acetylamino-1-aminobenzene-2-sulphonic --> 1-naphthol-3 : 6-disulphonic acid is hydrolysed, diazotized and coupled with m-toluidine. Specification 838,337 is referred to.
