ABSTRACT:
Metal complex compounds which in the form of the free acids correspond to the formula I ##STR1## where A is an aliphatic, carbocyclic or heterocyclic radical,
E is an aliphatic or carbocyclic radical,
B is a cyano, acyl, substituted sulfonyl, carboxylic acid ester or carboxamide radical, or
B and E together with the carbon atoms by which they are linked may be an alicyclic or heterocyclic radical,
F is an aliphatic, carbocylic or heterocyclic radical,
L is --O--, --COO--, ##STR2## n is 1, 2, 3 or 4, Y is .dbd.CH-- or .dbd.N-- and
Z is ##STR3## or the radical of a coupling component, alkyl being of 1 to 4 carbon atoms, and
R is hydrogen or unsubstituted or substituted alkyl, cycloalkyl, aryl or acyl and R.sup.1 and R.sup.2 are substituents conventionally present in dyes.
The compounds of the formula I give fast dyeings on natural polyamides and synthetic nylons.
