摘要:1. Water-soluble copper-complex disazo compounds of the general formula (1)see diagramm : EP0085378,P48,F1 in which : m is the number zero or 1 (where in the caseof m = 0 this group is hydrogen) ; the free azo group can be bonded in 6- or 7-position tothe centrally located naphthalene nucleus ; if m is equal to 1, this sulfo group is bondedin the 5-position when the azo group is in the 6-position, and is bonded in the 6-positionwhen the azo group is in the 7-position ; R**1 is a hydrogen atom or straight-chain orbranched alkyl group having 1 to 4 carbon atoms which can be substituted ; R**2 is ahydrogen atom or a cycloalkyl group which can be substituted by 1 to 3 methyl groups,or a straight chain or branched alkyl group having 1 to 4 carbon atoms which can besubstituted, or an optionally substitued aryl radical ; R**1 and R**2 can be identical to ordifferent from each other ; or R**1 and R**2 are alkylene groups having 1 to 4 carbonatoms and form together with the nitrogen atom and optionally an oxygen, sulfur ornitrogen atom as a further heteroatom a heterocyclic 6-membered radical ; Y is the vinylgroup or a group of the general formula (2) -CH2 -CH2 -X (2) in which X denotes an

inorganic or organic radical which can be eliminated under alkaline conditions ; M is ahydrogen atom or the equivalent of a metal.
