ABSTRACT:
Phthalocyanine dyes, in particular copper phthalocyanine and nickel phthalocyanine dyes which contain one or more groups of the formula given and defined below ##STR1## or one or more carboxy groups or both groups and which furthermore can contain one or more sulfo groups, customary sulfonamide groups and/or groups of the formula given and defined below ##STR2## dye hydroxy- and/or carboxamide-containing materials, in particular fiber materials, such as cellulose fiber materials, wool and polyamide fibers, in fast, predominantly green hues of high color strength.
In the formulae: R is hydrogen or a lower substituted or unsubstituted aliphatic radical, A is an aromatic carbocyclic or aromatic heterocyclic radical or an alkylene radical, which may be interrupted by 1 or 2 hetero groups, X is a direct bond or a divalent organic bridging member or together with the group --N(R)-- forms the divalent radical of a saturated heterocycle containing two N atoms, Y, in the case where A is an aromatic radical, is a direct bond or a carbamoylalkylene group or a methylene, ethylene, methylamino or .beta.-cyanoethylamino group, or Y is lower alkylene, in which case the grouping --X--A-- must be a direct bond and m is 2, Z is a fiber-reactive group of the vinylsulfonyl series and m is the number 1 or 2.
