The new dyestuffs are especially suitable for dyeing and printing fiber materials, such as silk, wool, synthetic polyamide or polyurethane, and above all, native and regenerative cellulose. They possess a very high fiber reactivity so that they fix on the fiber material very rapidly even at low temperatures and are thus very suitable in continuous dyeing processes.

Abstract: Dyestuffs of the formula (1) ##SPC1##Wherein A is an optionally substituted radical of the benzene or naphthalene series which, however, does not contain a sulfonic acid group, B is the radical of a coupling component of the benzene, naphthalene, pyrazolone, aminopyrazole, hydroxyquinoline or aceto-acetyl-arylamide series, which, however, does not contain a sulfonic acid group, and R is hydrogen or the lower alkyl.These dyestuffs are very well water-soluble in spite of having a high molecular weight and containing only one sulfonic acid group. They are especially suitable for dyeing or printing materials of natural and synthetic nitrogen-containing fibers, such as wool, silk, polyamide or polyurethane fibers, preferably if dyed from an acid to neutral dye bath. They show a very good colour buildup and migration power when being applied on the material mentioned which allows to obtain even dyeings of good fastnesses to light and to wet processing, for example, to washing and to perspiration.

Abstract: 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.
