ORGANIC COMPOUNDS

摘要

Compounds of the formula +TR 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 R1 and R2 is independently hydrogen or C1-6 alkyl, each R4 is independently hydrogen, halo, hydroxy, C1-4 alkoxy, C1-4 alkyl, carboxy or sulfo, each R6 is hydrogen, cyano, carbamoyl or wherein An (-) is a non-chromophoric anion, each R7 is hydrogen, C1-4 alkyl, C5-6 cycloalkyl, phenyl, benzyl, phenylethyl or carboxy, each W is linear or branched C2-6 alkylene; linear or branched C3-6 alkylene monosubstituted by hydroxy; linear or branched C2-6 alkylene interrupted by +TR wherein R11 is linear or branched C1-4 alkylene, m is 0 or 1, and the ** indicates the bond attached to the nitrogen atom of the pyridone ring, or 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 R3 is independently hydrogen, C1-4 alkyl or C2-4 hydroxyalkyl, each R5 is independently halo, amino or an aliphatic, cycloaliphatic, aromatic or heterocyclic amino group, and each R12 is independently linear or branched C2-4 -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.
