    摘要： Monoazo dyestuffs which in the form of the free acid correspond to the general formula ##STR1## wherein R.sub.0, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6 and R.sub.7 have the meaning given in the description and their use for the dyeing of natural and synthetic fibre materials, especially for dyeing polyamide fibres. Dyeings obtained distinguish themselves by very good fastness to light. Dyestuffs are absorbed well on polyamide fibres already in a neutral to weakly acid dye bath. By polyamide fibres there are here especially understood those from synthetic polyamides such as .EPSILON.-polycaprolactam, or condensation products of adipic acid and hexamethylenediamine.

    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.
