Abstract
The invention comprises monoazo dyes which in the free acid form are of formula <FORM:0926327/IV(a)/1> wherein R is a halogen atom, a nitro, acylamido or substituted amino group other than mono-alkylamino or a 11:21:4:5-naphthatriazolyl group which may be substituted by sulphonic acid groups, X is a phenylene or naphthylene radical which may be substituted other than by amino or monoalkylamino, Y is hydrogen or an alkyl radical and T is a trihalogenopyrimidyl radical. They are prepared by condensing a tetrahalogenopyrimidine with an appropriate aminoazo dye. The dyes give red, orange and violet shades on cellulose and nitrogenous fibres. In an example the aminoazo dye 4-amino-41-nitrostilbene-2:21-disulphonic acid --> aniline is condensed with tetrachloropyrimidine. Further dyes are specified in examples. Specification 902,618 is referred to.
