<p>1. A copper complex formazan compound of the general formula (1) see diagramm : EP0135040,P17,F1 in which A is a benzene or naphthalene nucleus both of which are necessarily substituted by the indicated sulfo group -SO3 M (where M has the meaning given below) in the ortho-position relative to the N-atom of the hydrazone component, and which may be substituted by one to three substituents from the group comprising halogen, nitro, alkyl of 1 to 5 carbon atoms, lower alkylaminoalkyl, alkoxy of 1 to 4 carbon atoms, hydroxy, alkylsulfonyl of 1 to 4 carbon atoms, phenylsulfonyl, sulfamoyl, N-mono- and N,N-dialkylsulfamoyl with in each case 1 to 4 carbon atoms in the alkyl, lower alkanoylamino, aroylamino, N-mono- and N,N-dialkylamino with in each case 1 to 4 carbon atoms in the alkyl, phenyl and phenylsulfamoyl ; B is a benzene or a naphthalene nucleus both of which may be substituted by substituents from the group comprising hydroxy, nitro, halogen, alkyl of 1 to 5 carbon atoms, alkoxy of 1 to 4 carbon atoms, carbalkoxy having 1 to 4 carbon atoms in the alkyl radical, amino, N-mono- and N,N-dialkylamino with in each case 1 to 4 carbon atoms in the alkyl, and phenylsulfamoyl, or B is the radical of a furan, thiophene, pyrrole, imidazole, pyrazole, pyridine, quinoline or benzimidazole, each being optionally substituted by lower alkyl, lower alkoxy, chlorine, benzyl, phenethyl and/or phenyl, or B is a direct bond or a straight-chain or branched alkane radical of 1 to 3 carbon atoms or a straight-chain or branched alkene radical of 2 to 8 carbon atoms, and these alkane and alkene radicals may be further substituted by the phenyl radical which in turn may be substituted by substituents from the group comprising methyl, ethyl, methoxy, ethoxy, fluorine, chlorine, bromine and sulfamoyl ; M is a hydrogen atom or the equivalent of a metal ; X is a hydrogen atom or a sulfo group ; Z is a hydrogen atom or a group which confers watersolubility which - besides the sulfo group necessarily required in the o-position relative to the N-atom of the hydrazone component A - is bonded to A once or twice on an aliphatic or aromatic carbon atom of A, preferably on an aromatic nucleus, and Z**1 is a hydrogen atom or a group which confers watersolubility which is bonded to B once or twice on an aliphatic or aromatic carbon atom of B, preferably on an aromatic nucleus ; Z and Z**1 together denoting not more than three sulfo groups if X is a sulfo group ; Y is the vinyl group or a group of the formula -CH2 -CH2 -E, in which E is a substituent which can be eliminated under alkaline conditions.</p> |
