ABSTRACT:
A monoazo dye mixture which is the reaction product of the diazo base of 7-amino-4-nitrobenzotriazole and a coupling component of the formula ##STR1## wherein R.sub.1 is H or lower alkoxy; R.sub.2 is an alkyl radical having 1-4 carbon atoms, phenyl, tolyl, or chlorophenyl; and n has a value of 1-2. The hydroxyalkyl groups of the coupling component are reacted prior or subsequent to coupling with at least stoichiometric quantities of both: (1) a lower alkyl chlorocarbonate, lower alkanoyl chloride, benzoylchloride, methylbenzoylchloride, ethylbenzoyl chloride, phthaloyl chloride, isophthaloyl chloride, ter phthaloyl chloride or lower alkylsulfonyl chloride and (2) a mono- or di-lower alkyl formamide or acetamide, at a temperature of 30.degree.-100.degree. C until the reaction mixture is substantially free of unreacted hydroxyalkyl groups. The dye mixture produces excellent dyeings on polyester fabric materials.
