Monoazo dyes of the benzisothiazole series which are not soluble in water

摘要

Monoazo dyes having a diazo component derived from a 4-amino-7-nitro-1,2-benzisothiazole optionally substituted in the 5-position by chlorine, bromine, nitro or cyano and a substituted aniline as coupling component. The dyes are eminently suitable for dyeing synthetic linear polyesters.
