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…
