Disperse monoazo dyestuffs, free from carboxylic and sulphonic acid groups, derived from 3,5-dinitro-2-amino thiophene as disazo component and an arylamine coupling component exhibit superior properties when used to give colorations to textile materials such as secondary cellulose acetate and cellulose triacetate, polyamide and aromatic polyester textile materials, said colorations having excellent fastness to light and to wet and dry heat treatments. The dyestuffs also have high tinctorial strength and excellent dyeing and build-up properties and produce depths of shade which are relatively independent of the dyebath pH, or the temperature of the dyebath or the liquor ratio of the dyebath.
这些分散的单偶氮染料,不含羧基和磺酸基,由3,5-二硝基-2-氨基噻吩作为二偶氮组分和芳胺偶联组分衍生而来,用于给予织物材料如次级醋酸纤维素和三醋酸纤维素、聚酰胺和芳香族聚酯纤维材料的着色时,表现出卓越的性能,这些着色具有优异的耐光、耐湿和耐干热处理性。这些染料也具有高染色力和优异的染色和建立性能,并产生相对独立于染液pH、染液温度或染液比的色深。
