    Abstract: 1. Water-soluble copper-complex disazo compounds of the general formula (1) see diagramm : EP0084849,P29,F1 X is a chlorine atom or a group of the formula (2a), (2b) or (2c) see diagramm : EP0084849,P29,F2 in which R**1 denotes a straight-chain or branched alkyl group of 1 to 4 carbon atoms which can be sustituted, or an optionally susbtitut aryl radical, or represents a hydrogen atom, R**2 denotes a straight-chain or branched alkyl group of 1 to 4 carbon atoms which can be sustituted, or represents an optionally substituted aryl radical, R**3 is a hydrogen atom or denotes a straight-chain or branched alkyl group of 1 to 4 carbon atoms which can be susbtituted, and R**4 is a hydrogen atom or represents a cycloalkyl group which can be substituted by 1 to 3 methyl groups, or denotes a straight-chain or branched alkyl group of 1 to 4 carbon atoms which can be susbtituted, or is an optionally susbtituted aryl radical, and R**3 and R**4 can be identical or different, or R**3 and R**4, as alkylene radicals of 1 to 4 carbon atoms, together with the nitrogen atom and optionally an oxygen, sulfur or nitrogen atom as a further heteroatom, form a heterocyclic 6-membered radical ; Y is the vinyl group or a group of the general formula see diagramm : EP0084849,P30,F3 in which R denotes an inorganic or organic radical which can be eliminated under alkaline conditions ; Z is a chlorine atom ; M is a hydrogen atom or the equivalent of a metal.
