    Abstract: A process for the preparation of water-soluble phthalocyanine dyestuffs containing a fiber-reactive group of the vinylsulfone series, by reacting phthalocyanine sulfochlorides, optionally containing sulfo groups, with a primary or secondary amine which contains a fiber-reactive group of the vinylsulfone series, and optionally with a further primary or secondary amine in common manner, wherein according to the invention a pyridine-sulfonic acid or a pyridine-carboxylic acid is used as catalyst instead of the pyridine, as used previously. The use of pyridine-sulfonic acids or pyridine-carboxylic acids-which results in the same good reaction rate and yield as the use of pyridine in the preparation of phthalocyanine dyestuffs-avoids the considerable drawbacks occurring in the preparation on an industrial scale, which drawbacks are caused by the toxic properties and the unpleasant smell of the pyridine.
