Water soluble copper-complex phenylazonaphthyl and naphthylazonaphthyl

Abstract

Water-soluble copper complex monoazo compounds of the general formula (1) ##STR1## in which D denotes the radical of a diazo component of the benzene or naphthalene series with the oxy group in the ortho-position relative to the azo bridge, K denotes the radical of a coupling component of the benzene, naphthalene, pyridone or pyrazolone series with the phenolic or enolic oxy group in ortho-position relative to the azo group, R denotes hydrogen or alkyl of 1 to 4 C atoms, Y denotes the radical of the formula --NH--, --N(lower alkyl)-- or --CH.sub.2 --, n represents the number zero or 1, Z denotes the vinyl, .beta.-acetoxyethyl, .beta.-thiosulfatoethyl, .beta.-chloroethyl or .beta.-sulfatoethyl group and X denotes a radical of the general formula (2a), (2b) or (2c) ##STR2## in which R.sup.1 is an optionally substituted alkyl radical, an optionally substituted aryl radical or an optionally substituted heteroaromatic radical, R.sup.2 is a hydrogen or an optionally substituted alkyl radical or a cycloaliphatic radical and R.sup.3 is a hydrogen atom or an optionally substituted alkyl radical or an optionally substituted aryl radical, or R.sup.2 and R.sup.3, together with the nitrogen atom, form a heterocyclic saturated ring which may contain a further hetero atom, and in which the groups of the formulae (3) and (4) ##STR3## in which R, X, Y, Z and n have the abovementioned meaning, are bonded to the radical D and the radical K, either separately from one another or simultaneously to D or K. The new compounds have valuable fiber-reactive dyestuff properties and dye, for example, cellulose fiber materials and polyamide fiber materials, in fast, deep shades.
