摘要：
Water-insoluble azo-dyestuffs of the formula
said compounds being suitable for the dyeing or printing of synthetic fibrous materials, such as fibrous materials of celluloseacetates, polyamides, polyurethanes, polyolefins, polycarbonates and, particularly, polyesters, the dyeings obtained on these fibres being distinguished by a very good fastness to wet processing, ironing, waste gas and light and by a very good building up.
and R2 represents hydrogen, lower alkyl, -lower alkylene-OH, lower alkylene-CN,
R1 represents lower alkyl, lower alkylene-OH,
WHEREIN IN WHICH D represents nitro-phenylene, dinitro-phenylene, carbo-lower alkoxy-phenylene, chloro-nitro-phenylene, cyano-nitrophenylene, dichloro-nitro-phenylene, chloro-bromo-nitrophenylene, chloro-dinitro-phenylene, bromo-dinitro-phenylene, chloro-lower alkyl sulfonyl-phenylene, nitro-lower alkylsulfonyl-phenylene, bromo-cyano-nitro-phenylene, chlorotrifluoromethyl-phenylene, phenylazo-phenylene, nitrothiazolyl, carbo-lower alkoxy-thiazolyl or nitrobenzothiazolyl, A represents hydrogen, chlorine, lower alkyl, lower alkoxy or O-lower alkylene-lower alkoxy, B represents hydrogen, chlorine, lower alkyl, lower alkoxy, lower alkyloylamino, benzoylamino,
