They are prepared by (a) reacting a compound of general formula wherein R 8 is H, Cl, Br or -SO 3 M and M is an alkali metal or alkaline earth metal cation with a compound of the general formula where m, R 1 , R 2 and R 3 are as defined above or by (b) condensing a compound where m = 1 and R 2 + R 3 = COOH or an acid chloride or C 1 -C 4 alkyl ester thereof with an amine. Reaction (a) preferably takes place in an inert organic solvent at 0-200 C. advantageously in presence of a mild oxidizing agent. Reaction (b) preferably takes place in an inert anhydrous organic solvent at 20-250 C. The dyestuffs are used as disperse dyes in polyesters and for mass coloration of lacquers, viscose or cellulose acetate spinning solutions, polyethylene, polystyrene, P.V.C. rubber, synthetic leather, printing inks and paper. | ||||||
