ABSTRACT:
New compounds had been found which correspond to the formula ##STR1## as well as processes for preparing them by sulfonation of 3.beta.-sulfato- or 3-.beta.-hydroxyethylsulfonyl - aminobenzene. The novel compounds are valuable intermediary products for the preparation of azo fibre-reactive dyestuffs which have very good dyeing properties and a high fibre-reactivity yielding dyeings of excellent fastnesses, especially to light and wet processing.
