Abstract

Aromatic polyester fibres, yarns, fabrics and ribbons are dyed with an aqueous suspension of an azo dyestuff of the formula: <FORM:0811723/IV (c)/1> in which X1 represents as an optional substituent a halogen atom or an alkyl or alkoxy group and X2 represents as an optional substituent a halogen atom or an alkyl, alkoxy or nitro group. Dyeing is preferably effected at an elevated temperature. Several dyestuffs of the above formula are specified. The dyestuffs may be prepared by alkylating the corresponding hydroxy-azo-dyestuffs or by coupling a diazotized base that couples energetically, such as 4-nitro-1-aminobenzene, with a 1 : 3-dialkoxybenzene or a 1-alkyl-3-alkoxybenzene.
