Abstract: Process for the preferably continuous manufacture of waterinsoluble azo dyestuffs on textile materials made of cellulose fibers, which comprises carrying out, after the application of the coupling component and of the diazo component from an aqueous dye bath, the finishing operation of the dyeings in organic solvents. The diazo component is in the form of a diazo-amino compound capable of being split up or of an anti-diazotate of a primary aliphatic amine. The organic solvent a hydrocarbon which may be halogenated, aromatic or cycloaliphatic.
Abstract translation: 用于在由纤维素纤维制成的纺织材料上优选连续制造水不溶性偶氮染料的方法，其包括在从染料浴中加入偶联组分和重氮组分后进行染色的整理操作 有机溶剂。 重氮组分是能够分裂的重氮 - 氨基化合物或主要脂族胺的抗重氮酸酯的形式。 有机溶剂是可以被卤化的芳族或脂环族烃。
