    摘要： Azo dyestuffs which contain, as the coupling component an indole of the formula ##STR1## wherein R denotes an optionally substituted alkyl radical, an optionally substituted aryl radical or an optionally substituted aralkyl radical, and the benzene ring A can be further substituted,frequently exhibit an undesired irreversible change in the color shade in acid solutions, which surprisingly can be prevented by adding nitrogen-containing complex-forming substances.

The dyestuffs are suitable for dyeing nitrogen-containing materials especially for dyeing synthetic polyamide and polyurethane fibers. The dyestuffs are very well absorbed on the polyamide fibers both from an acid dyebath and from a neutral dyebath. In one example synthetic polyamide fibers are dyed in clear shades having good to very good fastness properties.
