Phthalocyanine compounds having fiber-reactive dye properties which dye hydroxyl- and/or carboxamido-containing material, in particular fiber material, such as cellulose fibers, wool and synthetic polyamide fibers, in fast and deep shades and which conform to the general formula (1) <IMAGE> (1) where Pc is the radical of copper- or nickel-phthalocyanine whose benzene nuclei can be substituted by chlorine or phenyl, R is a hydrogen atom or an alkyl group of 1 to 4 carbon atoms which can be substituted by a hydroxy, sulfato, cyano or sulfo group, M is a hydrogen atom or one equivalent of a salt-forming metal, preferably a hydrogen atom or an alkali metal, Y is a vinyl group or preferably a beta -sulfatoethyl group, R1 is a hydrogen atom or an alkyl group of 1 to 4 carbon atoms which can be substituted, and R2 has one of the meanings of R1 and is identical to R1 or different from R1 or -NR1 R2 together form a group of the formula (2) <IMAGE> (2) where M has the abovementioned meaning, m is the number 1, 2, 3 or 4, a is an integral or fractional number from 1 to 4, b is an integral or fractional number from zero to 3, and c is an integral or fractional number form zero to 3, with the proviso that the sum of (a+b+c) is an integral or fractional number from 2 to 4, the sulfonamide and sulfo groups are each bonded to the carbocyclic aromatic rings of the phthalocyanine in the 3- and/or 4-position.
