Abstract
The invention comprises dyes which, in their acid free form, are of formula <FORM:0838343/IV(c)/1> where A may bear substituents other than hydroxyl and amino groups, X is H or a substituent other than Hlg and one of Y1 and Y2 is H and the other H or SO3H. They may be made by coupling an appropriate diazotized o-anilinesulphonic acid with the necessary triazine component or by reacting an appropriate aminoazo dye with cyanuric bromide. The aniline sulphonic acids and aminoazo dyes to be used are those of the parent Specification, which also discloses preferred reaction details. Indicated as triazine components are the products of reaction of cyanuric bromide and 1-amino-8-naphthol-6-mono- and -3,6- and -4,6-di-sulphonic acids. The dyes dye or print cellulosic materials by methods which preferably include an alkali treatment vide Specification 797,946. Red shades are obtained. An example is given of the preparation of a dye from cyanuric bromide and the hydrolysis product of the dye orthanilic acid --> 1-acetylamino-8-naphthol-3,6-disulphonic acid.
