Abstract
There are described novel dyes of the formulae ##STR1## in which R.sub.1 and R.sub.2 independently of one another are each hydrogen, unsubstituted or substituted alkyl, cycloalkyl, aralkyl or aryl, and R.sub.1 and R.sub.2 together with the nitrogen atom, and optionally with the inclusion of further hetero atoms, can also form a 5- to 7-membered heterocycle, or one of the radicals R.sub.1 or R.sub.2 can be linked with the carbon atoms, in the o-position with respect to the amino group, of the ring A to form a fused-on, saturated, unsubstituted or substituted 5- or 6- membered ring,
