Process for the preparation of water-soluble phthalocyanine dyestuffs |
| abstract |
Water-soluble phthalocyanine dyestuffs having vinylsulfonyl or β-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 β-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. |
