Abstract
The invention comprises the azo dyes of formula <FORM:0988909/C4-C5/1> wherein R is a hydrogen atom or an alkyl radical, R1 and R2 are methyl radicals and R3 and R4 are hydrogen atoms or methyl radicals, or when R3 and R4 are hydrogen atoms R1 and R2 are joined to form a tetramethylene or pentamethylene radical, or R1 and R3 and R2 and R4 are joined to form in each case a tetramethylene radical; X is a divalent mono- or di-chloropyrimidyl, 5-cyano chloropyrimidyl radical or a divalent 1,3,5-triazinyl radical substituted in the 6-position by a hydrogen atom or an alkyl, alkoxy, phenyl, phenoxy, amino or substituted amino group; D is the residue of a diazo component of the benzene, naphthalene or stilbene series or a benzene or naphthalene radical substituted by a phenylazo or naphthylazo group and E is the residue of a 5-pyrazolone, 5-aminopyrazole or acylacetanilide coupling component. The dyes are prepared by reacting an azo compound of formula <FORM:0988909/C4-C5/2> with a hydrazine of formula <FORM:0988909/C4-C5/3> or by coupling a diazonium compound from an amine D-NH2 with a suitable coupling component containing a residue of formula <FORM:0988909/C4-C5/4> The dyes may be applied to polyamide and preferably cellullse fibres by the usual reactive dye processes. Examples describe the preparation of the dyes and their use.
