Water-soluble phthalocyanine dyes, processes for their preparation and

Abstract

There are described water-soluble phthalocyanine dyes, in particular copper phthalocyanine and nickel phthalocyanine dyes, which have the formula (1) defined hereinafter and can be used for the dyeing and printing of hydroxy and/or carboxyamido-containing fiber material, such as cotton, wool and synthetic polyamide, by the techniques customary in the art for fiber-reactive dyes. ##STR1## in which Pc is a phthalocyanine radical, R.sup.1 and R.sup.2 are both hydrogen or alkyl, A is an aromatic carboxylic or heterocyclic radical, which may be substituted by substituents customary in dyes, or is an alkylene radical, which may be substituted by 1 or 2 hetero groups, X is a direct bond or a divalent organic binding link, such as an alkylene radical or an alkyleneamino group, Y is a direct bond or a group of the formula --CO--NH--alkylene-- or a methylamino or .beta.-cyanoethylamino group, Z is a fiber-reactive radical from the vinylsulfonyl series or is .beta.-hydroxyethylsulfonyl, m is the number 1 or 2, W is halogen, sulfo, phenylsulfonyl, alkylsulfonyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms or substituted or unsubstituted aryloxy or W is an amino group of the formula (2) or (3) ##STR2## in which R.sup.2, X, A, Y, Z and m have one of the above-mentioned meanings, and R.sup.3 is hydrogen or substituted or unsubstituted alkyl or cycloalkyl and R.sup.4 is hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted phenyl or cyano, or R.sup.3 and R.sup.4, together with the nitrogen atom, form a heterocyclic ring, a is a number from 1 to 4 and b is a number from zero to 3, and the sum of (a+b) is a number from 1 to 4, and M is a hydrogen atom or an alkali metal or another salt-forming metal.
