    摘要: The invention relates to water-insoluble azo dyestuffs of the formula ##SPC1##In which A represents the residue of a diazo component of the azobenzene series, R.sub.1 a hydrogen atom or an alkyl group which may be substituted which may be substituted, R.sub.2 an alkyl group which may be substituted, R.sub.3 represents a divalent organic residue which together with the grouping ##EQU1## may form a 5- to 7-membered heterocycle, and X represents a hydrogen atom or an alkyl, alkoxy, aryloxy or arylmercapto group. The dyestuffs dye polyester fibre in orange, red or blue shades with good fastness: the use of such succinimido containing azo dyestuffs in imparting blue to red color to fibers or fabrics of wool, cellulose triacetate, polyamides and polyesters. The dyeings display excellent fastness to light, sublimation and abrasion on polyester fibers.
