Abstract: Metal complex compounds which in the form of the free acids correspond to the formula I I 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-, n is 1, 2, 3 or 4, Y is =CH- or =N- and Z is 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 R1 and R2 are substituents conventionally present in dyes. The compounds of the formula I give fast dyeings on natural polyamides and synthetic nylons.

Abstract: 2:1-chromium complex dyes of the formula: in which: A is the radical of a carbocyclic diazo component with a complex-forming hydroxy or carboxy group adjacent to the azo bridge; B is the radical of a carbocyclic, heterocyclic or open-chain coupling component with a complex-forming hydroxy or amino group adjacent to the azo bridge; D is the radical of a carbocyclic aldehyde with a complex-forming hydroxy group adjacent to the azomethine bond; E is an aliphatic radical with a complex-forming amino group; and n is the number of carboxy groups not participating in the formation of the complex and the sulfonic acid groups. The dyes are eminently suitable for dyeing natural and synthetic polyamides, clear shades with good fastness properties being obtained.
