Title: Process for the preparation of fiber-reactive dyestuffs

Abstract: A fiber-reactive dyestuff mixture is obtained by reacting a phthalocyanine sulfochloride with an aromatic amine having a fiber-reactive group selected from vinyl sulfonyl, .beta.-sulfatoethyl-sulfonyl and .beta.-hydroxyethyl-sulfonyl groups, diazotizing unreacted amine in the resulting mixture and reacting the diazo compound in the mixture with a conventional coupling component to form a mixture of phthalocyanine and azo dyestuffs.
