    摘要: New water-soluble anthraquinone-azo compounds of the general formula ##STR1## and their salts; in this formula the R.sub.1 s both are sulfo groups, or one of the two is a hydrogen atom and the other is a sulfo group, R is hydrogen or lower alkyl and D, as the radical of a diazo component, is the benzene or naphthalene nucleus, which is monosubstituted or disubstituted by a fiber-reactive group Z, corresponding to the index n being 1 or 2, and which furthermore can be substituted by 1 to 3 substituents selected from lower alkyl, lower alkoxy, halogen, nitro and sulfo. The new azo compounds are very suitable as dyestuffs for dyeing fiber materials containing hydroxy groups or carbonamide groups, such as natural or synthetic polyamide fibers or polyurethane fibers and cellulose fibers, yielding deep dyeing and prints with very good fastness properties to wet processing and very good fastness properties to light.The new compounds of the above formula are obtained by diazotizing a 1-amino-2-sulfo-4-(4'-aminophenyl)-aminoanthraquinone compound, which is substituted by sulfo in the 2'- and/or 5'-position, by means of an equivalent amount of sodium nitrite in the presence of a mineral acid, coupling this diazonium salt with an acetylsuccinic acid ester of a lower alkanol, cyclizing this radical of the coupling component to the pyrazolone ring and coupling the pyrazolono-phenylamino-anthraquinone compound, thus obtained, with a diazonium compound of an amine of the formulaH.sub.2 N--D--Z.sub.nD, Z and n being defined as above. Up to the stage of the coupling reaction with the diazonium compound of the aforementioned amine, these reactions can be carried out as a "one-pot" reaction without intermediate isolation of intermediate products.

    摘要: Novel, valuable unsymmetrical 1:2-cobalt complex dyestuffs of an azo compound and an azomethine compound have been found which are well suited for the dyeing of natural and synthetic polyamide fibres, yielding even dyeings of high fastnesses to wet processing and use as well as to light. The novel dyestuffs can be prepared either by cobalting the equimolar mixture of the metalfree azo and azomethine dyestuffs with a cobalt-yielding compound at a pH of 5 to 10 at 60 .degree. to 150.degree. C., or by first cobalting the azomethine compound and then reacting it with the equimolar amount of the metalfree azo compound. The compounds are 1:2-cobalt complex compounds of the compounds ##STR1## in which R.sub.1 is chlorine, lower alkyl or nitro, R.sub.2 is hydrogen, lower alkyl or lower alkoxy, R.sub.3 is hydrogen, chlorine, nitro or lower alkyl, Z is ##STR2## in which R.sub.4 is hydrogen, lower alkyl or lowr alkoxy, R.sub.5 is hydrogen, lower alkyl or lower alkoxy, X is hydroxy, sulfoalkyl of from 1 to 4 carbon atoms, or ##STR3## R.sub.9 is hydrogen or lower alkyl, and R.sub.6 and R.sub.7 are different from each other and each is nitro or sulfo.
