Abstract

The invention comprises disperse azo dyes of formula D-(SO2R)n where D is an azo dye residue, R is CH2. CHOH. CH2X, CH= CH. CH2OH or CH=CH.CH2X where X is Cl or Br and n is 1 or 2, provided that D is free from SO3H and COOH groups and that each of the SO2R groups is attached to a carbon atom of an aryl ring present in D. The dyes are made by conventional diazotisation and coupling processes. Representative of specified diazo components are aniline, 2-chloro-4-nitroaniline, 2 - amino - 5 - nitrobenzonitrile, p - aminobenzenesulphonamide, 4 - amino - 3 - chlorophenyl methyl sulphone, 2-amino-5-cyanobenzotrifluoride, 2-amino-5-nitrothiazole, 2-amino-6-methoxybenzthiazole, 4-(31-chloroprop-11,21-enylsulphonyl) aniline, 2-amino-4-(31-chloro-21-hydroxypropylsulphonyl) - anisole, 2 - chloro - 4 - (31-hydroxyprop - 11,21 - enylsulphonyl) aniline, 4 - amin - 2,5 - dimethoxy - 4 - nitroazobenzene and 6 - (31 - hydroxyprop - 11,21 - enylsulphonyl) - 2 - naphthylamine. Examples of specified coupling components are p-cresol, 2-hydroxy-5,6,7,8- tetrahydronaphthalene, 3-methyl-and-carbethoxy-5-pyrazolones, 1-o-phenyl-3-methyl-5-pyrazolone, 1 - [31-and 41 - (311 - chloro - 211 - hydroxypropylsulphonyl) - phenyl - 3 - methyl - 5 - pyrazolone, 3- and 4-(31-hydroxyprop-11,21-enylsulphonyl) -acetoacetanilide, 6 - (31 - chloroprop - 11, 21 - enylsulphonyl) - 2 - naphthol, 2 - hydroxy - 3 - naphthoic anilide, 1-carboethoxyamino-7-naphthol, 2,4-dihydroxyquinoline, barbituric acid, 1 - naphthylamine, N,N - di - (b - hydroxyethyl) aniline and 6-sulphonyl-2-naphthylamine. Preferred are dyes of formula A(SO2R)-N=N-E where A is a benzenic residue and E is a coupling component residue containing an amino, or substituted amino, group o or p to the azo group. The dyes colour textile materials comprising natural and synthetic fibres, e.g. polyamide, modified polyacrylonitrile, aromatic polyester, rayon, cellulose triacetate, wool and cellulosic fibres. Disperse colouring processes are used. Yellow to blue shades are obtained. Examples are provided of the preparation of the dyes and their use in colouring processes.
