Abstract
The invention comprises dyes which, in their acid free form, are of formula <FORM:0838342/IV(c)/1> where A may contain substituents other than hydroxyl or amino groups, X is H or a substituent other than halogen, and R is H or an alkyl radicle. They may be made by coupling an appropriate diazotized o-aniline sulphonic acid with the necessary triazine coupling component or by reacting an appropriate aminoazo-compound with cyanuric bromide. The aniline sulphonic acids and aminoazo compounds to be used are those of the parent Specification which also discloses preferred reaction details. Indicated as N-alkyl substituents in the coupling components are methyl, ethyl, butyl and hexyl groups. The dyes dye or print cellulosic materials by methods which preferably include an alkali treatment vide Specification 797,946. Orange shades are obtained. An example is given of the preparation of a dye from cyanuric bromide and the hydrolysis product of the dye 2 - aminobenzene sulphonic acid -\sZN - acetyl 2-amino-5-naphthol-7-sulphonic acid.
