Sulfo group-containing metal phlhalocyanine azo compound having a 6-hydroxypyrid-2-one coupling component radicals having a fiber-reactive group

Abstract

Compounds of the formula ##STR1## and water-soluble salts thereof each cation of which is independently a non-chromophoric cation, wherein Me is cobalt, copper or nickel, Pc is the phthalocyanine radical, each R.sub.1 and R.sub.2 is independently hydrogen or C.sub.1-6 alkyl, each R.sub.4 is independently hydrogen, halo, hydroxy, C.sub.1-4 alkoxy, C.sub.1-4 alkyl, carboxy or sulfo, each R.sub.6 is hydrogen, cyano, carbamoyl or ##STR2## wherein An .crclbar. is a non-chromophoric anion, each R.sub.7 is hydrogen, C.sub.1-4 alkyl, C.sub.5-6 cycloalkyl, phenyl, benzyl, phenylethyl or carboxy, each W is linear or branched C.sub.2-6 alkylene; linear or branched C.sub.3-6 alkylene monosubstituted by hydroxy; linear or branched C.sub.2-6 alkylene interrupted by ##STR3## wherein R.sub.11 is linear or branched C.sub.1-4 alkylene, m is 0 or 1, and the ** indicates the bond attached to the nitrogen atom of the pyridone ring, or ##STR4## wherein the ** is as set forth above, each Y is a fiber-reactive group, a is 1, 2 or 3, b is 0, 1 or 2, c is 1 or 2, with the provisos that a+b+c does not exceed 4 and that each of the four units of the phthalocyanine nucleus contains a maximum of one substituent selected from those to which a, b and c relate, and n is 0 or 1, wherein each R.sub.3 is independently hydrogen, C.sub.1-4 alkyl or C.sub.2-4 hydroxyalkyl, each R.sub.5 is independently halo, amino or an aliphatic, cycloaliphatic, aromatic or heterocyclic amino group, and each R.sub.12 is independently linear or branched C.sub.2-4 -alkylene, and mixtures of such compounds and salts, useful for dyeing and printing hydroxy group- or nitrogen- containing organic substrates, for example leather and fiber materials containing or consisting of natural or synthetic polyamides or of natural or regenerated cellulose, preferably textile material containing or consisting of cotton.
