ABSTRACT:
Water-soluble phthalocyanine dyestuffs having vinylsulfonyl or .beta.-substituted ethylsulfonyl groups are prepared by reaction of phthalocyanine sulfonyl chlorides, which may contain sulfo groups, with a primary or secondary amine having vinylsulfonyl or .beta.-substituted ethylsulfonyl groups and, if appropriate, with a second primary or secondary amine of the aliphatic, heterocyclic or aromatic series, in the presence of a pyridinesulfonamide or pyridinecarboxamide.
