Abstract

The invention comprises basic monoazo dyes of formula <FORM:0972956/C4-C5/1> wherein R is an alkyl radical which may be substituted, X is a divalent atom or group which makes up a 5- or 6-membered aromatic ring, the heterocyclic system, which may have fused rings containing, if desired, substituents, A is a phenylene or naphthylene radical, Y is a D 2-pyrazolinyl-(1) radical which may be substituted, n is 0 or 1 and E is the equivalent of an anion. The dyes are prepared by (a) reacting a heterocyclic hydrazone or benzenesulphonylhydrazone of formula <FORM:0972956/C4-C5/2> wherein B is a hydrogen atom or a benzenesulphonyl radical in the presence of an oxidizing agent with an arylpyrazoline of formula H-A-Y or (b) by alkylating a dye of formula <FORM:0972956/C4-C5/3> The dyes may be used to colour silk, leather, furs, hair, mordanted cotton, synthetic polyamides and cellulose esters but are preferably used to dye and print textile materials of polyacrylonitrile or polydicyanoethylene in blue shades. Dyes having as heterocyclic ring systems benzthiazole, thiadiazole, thiazole, quinoline, triazole and indazole are specified in examples. Specifications 782,310 and 871,426 are referred to.
