Abstract

The invention comprises reactive, heavy metal-containing formazane dyestuffs of Formula I wherein A represents the radical of a diazo component which has a substituent X in the o-position to the azo bond X represents a metal-binding substituent R represents an optionally substituted aliphatic hydrocarbon radical, a cycloaliphatic radical or a carbocyclic-aromatic or heterocyclic-aromatic radical R1 represents hydrogen or a C 1-5 alkyl.group Y represents an acyl radical which forms at least one covalent bond with the substrate under dyeing conditions Z represents a salt-forming, water-solubilizing group which dissociates acid in neutral water. Me represents a heavy metal of the atomic numbers 24 to 30, and m represents a positive whole number of at most 7 by coupling the diazonium compound of an amine X1-A-NH 2 , wherein A has the meaning for Formula I, and X1 represents a metallizable group or a substituent which can be converted thereto during metallization with a coupling component of Formula III wherein Y, R1 and R have the meanings given for Formula I, and Q represents hydrogen or a substituent which can be replaced by azo coupling to form a formazane dyestuff of Formula IV wherein A, R, R1, Y, Z and m have the meanings given for Formula I, and X1 has that given for Formula II, the components being so chosen that the formazane dyestuff of Formula IV contains at most six Z groups, and reacting the formazane dyestuff obtained of Formula IV simultaneously or subsequently with an agent introducing a heavy metal Me to form a formazane dyestuff of Formula I. The dyes may be used to colour wool, silk, synthetic polyamides and polyurethanes and, in particular, cellulose fibres in green and blue shades.
