Abstract

The invention comprises dyes of formula <FORM:0838341/IV(c)/1> where A is an aryl nucleus free from amino, monoalkylamino or hydroxyl groups which contains an electronegative group o to the azo link and which may otherwise be substituted, one of Y1 and Y2 is H and the other H or SO3H, R is an alkyl radical of up to 4 carbon atoms and X is halogen. They are made by diazotizing appropriate amines, coupling, preferably in the presence of an alkali such as sodium carbonate, with the necessary naphtholic component containing a group -NHR and condensing the product with a cyanuric halide or by coupling the diazotized amine, preferably at pH 6-8, with the naphthol-triazine condensate. The product is preferably isolated at pH 6-8, buffering agents being used. Specified electronegative groups are SO3H, COOH, CN, SO2NH2, which may be substituted, sulphone and CF3. Other specified substituents for A are methyl, methoxy, ethoxy, CF3, Cl and Br. Specified groups for R are methyl, ethyl, propyl and butyl. Cl and Br are specified for X. Representative of specified naphthol components are 1-methyl-and -butyl-amino-8-naphthol-6-mono- and -3,6-and -4,6-di-sulphonic acids and of compounds corresponding to A are 4-aminoanisole-3-sulphonic acid, anthranilic acid, o - aminobenzene-sulphon-N-ethylanilide and -2-alkyl sulphone, 5-nitro-2-aminobenzonitrile and 2-naphthylamine-1-sulphonic acid. The products dye, as their alkali metal salts, silk, wool, regenerated protein and cellulosic textile materials from an aqueous bath in conjunction with treatment by an acid-binding agent vide Specification 797,946. They also dye wool, regenerated protein and modified polyacrylonitrile textile materials and, as in Specification 826,375, silk and polyamide materials from weakly acid or neutral baths. Textiles of silk, wool or regenerated protein may be printed by usual methods. Orange to red tints are obtained. Examples are provided of the preparation of the dyes and their use in dyeing processes.
