Abstract

The invention comprises dyes of formula:-X(-CO NH-A-SO2NH-D-Z)n where X is an n valent radical of a monoazo dye, A is an arylene residue, D an alkylene radical, preferably of 2-4 carbon atoms, Z is Hlg and n 1 or 2. The dyes are made in conventional fashion from appropriate diazo and coupling components or by treating monoazo dyes containing at least one carboxylic acid halide group with an aminoarylsulphonic acid halogen alkylamide. Indicated sulphohalogen alkylamides are aniline or naphthylamine sulphonic acid chlor- or brom-alkylamides which may contain substituents in the aryl residue such as alkyl, aryl, aralkyl, hydroxy, alkoxy, sulphonic acid, sulphonamide, sulphonhalogenalkylamide, nitro and halogen groups. Representative of specified compounds from which diazo components may be derived are 1-aniline-3- and -4-carboxylic acids and from which coupling components may be derived are 1-phenol-2-carboxylic acid, 1, 3-dihydroxybenzene-4-carboxylic acid and 2-naphthol-3-carboxylic acid. The dyes dye and print wool, silk, linear polyamides and especially natural or regenerated cellulose in the latter case preferably in the presence of an acid binding agent. Examples are provided of the preparation of the dyes and their use in dyeing cotton in red or yellow dyes typical of the compounds from which the diazo components used are derived are 5-nitro-2-amino-1-methoxybenzene, 2-naphthylamine-7-mono- and -6, 8-di-sulphonic acids, and aniline-4-sulphonic acid, typical compounds from which coupling components used are derived being 2-phenol-1-carboxylic acid, aniline-4-sulphonic acid, 2-naphthol-3-carboxylic acid, 1-acetamino-8-naphthol-3, 6-disulphonic acid, 1-naphthol-3-sulphonic acid, 1-naphthylamine-7-sulphonic acid, 2-amino-8-naphthol-3, 6-disulphonic acid and 1-(31-sulphophenyl)-3-methyl-5-pyrazolone. Specification 868,745 is referred to.
