    摘要： Water-soluble disazodyestuffs of the formula ##STR1## in which R.sub.1 and R.sub.2 are identical or different and each is hydrogen, methyl, ethyl or methoxy, and R.sub.3 is hydrogen, chlorine, nitro or alkyl of 1 to 4 carbon atoms, and their salts have been found which possess very good dyeing characteristics and are very well suitable for dyeing of synthetic polyamides and yield dyeings on these fibers with good to very good wet fastnesses and fastnesses to processing and to use. In accordance with this, an improved process had been found for coloring synthetic polyamide fibres by applying the above dyestuffs of the invention on said fibres in usual dyeing and printing methods and fixing them on the fibre by methods as usual in the art.
