Abstract
Polycyclic compounds of the general formula I ##STR1## in which the nucleus A can be further substituted, Y is a hydrogen atom or an optionally substituted hydrocarbon radical, and R.sub.1 and R.sub.2 each denote hydrogen, aryl, aralkyl, cycloalkyl or an aliphatic radical, and R.sub.1 and R.sub.2 can form a ring containing the amine nitrogen and mixtures thereof with one another. The dyestuffs dye natural and synthetic fibres in fast yellow and orange shades.
