Abstract

The invention comprises dyestuffs of formula <FORM:0806050/IV (c)/1> where R is a benzene residue fused to the thiazole ring as indicated, R1 is a benzene residue bound to the azo link in p-position to the thiazole ring, R2 and R3 are benzene or naphthalene residues and at least one of R and R1 contains a sulphonic acid group and groups R1-N=N-, -O-Cu- and -N=N- are in the 1-, 3-, 4-positions of R2. They may be made by treating dyestuffs of formul\mg <FORM:0806050/IV (c)/2> and <FORM:0806050/IV (c)/3> in conventional fashion with copper-yielding agents so that the desired dyestuffs are obtained The unmetallized dyestuffs are also made by conventional methods from appropriate components. Residues R and Rl may contain substituents such as chlorine atoms, methoxy or ethoxy groups and especially methyl and/or sulphonic acid groups. Preferred initial components are mono- and di-sulphonic acids of 2-(41 - aminophenyl) - 6 - methyl - benzthiazole. Middle components corresponding to R2 are preferably of the benzene series, the alkoxy group being advantageously a methoxy group. Specified components corresponding to R2 are 1-amino-2-methoxy-5-methyl- and -2,5-dimethoxy- and -diethoxy-benzenes, 1-amino-2-methoxy- and -ethoxy-naphthalenes and their 6-and 7-sulphonic acids and preferably 1-amino-2-methoxybenzene. Residue R3 advantageously contains a group imparting solubility in water such as a sulphonamide or carboxyl group and especially a sulphonic acid group. Specified components corresponding to R3 are aniline and its 2-methoxy, 2- and 4-carboxy, 3- and 4-sulpho- and sulphonamido- and 3-sulpho-4-methyl-derivatives and 2-aminonaphthalene-6-mono- and -4,8-sulphonic acids. The dyestuffs dye wool, silk and leather and especially cotton, linen and also regenerated cellulose and artificial silk. In examples illustrative of the preparation of the dyestuffs and their use in dyeing cotton in greenish or grey shades components used are selected from those listed above with the addition of 2-(41-aminophenyl)-benzthiazole-x-sulphonic acid as an initial component and aniline-3-carboxylic acid as a component corresponding to R3. Specification 719,363 is referred to.
