ABSTRACT:
New water-soluble azo compounds which have the general formula (1) ##STR1## in which K is the radical of a water-soluble coupling component which can couple at one or two positions in the molecule and which belongs to the series comprising aminobenzenes, phenols, naphthols, aminonaphthols, acylaminonaphthols, dihydroxynaphthalenesulfonic acids, phenylazoaminonaphtholsulfonic and naphthylazoaminonaphtholsulfonic acids, 5-pyrazolones and 5-aminopyrazoles and 2-hydroxy-6-pyridones, R represents an alkoxy group of 1 to 4 C-atoms and X a group of the formula --SO.sub.2 --CH.dbd.CH.sub.2 or --SO.sub.2 --CH.sub.2 --CH.sub.2 --Z in which Z is a group which can be eliminated under alkaline conditions, furthermore, the copper complex compounds of the above-mentioned metal-free compounds of the general formula (1). The novel metal-free compounds as well as the copper complex compounds have valuable dyestuff properties and are particularly suitable as fiber-reactive dyestuffs for dyeing and printing materials containing hydroxy or carbonamide groups, preferably fiber materials. The compounds of the invention produce deep dyeings which have very good fastness to nitrogen oxide and excellent fastness to wet processing such as fastness to boiling with sodium carbonate, fastness to washing at 60.degree. to 95.degree. C. and/or with peroxides, fastness to alkaline and acid perspiration, to water (under severe conditions), to alkalis and acids such as tartaric acid, to cross-dyeing, to bleaching with hypochlorite and to chlorinated water. The copper-complex compounds yield dyeings which are especially fast to light.
