Syntheses and Properties Studies on New Dispersed Dyes With Intermediate BIT

摘要

The target production were obtained by coupled reaction of 3-amino-5-nitro-2, 1- benzoisothiazole,as a diazo component,with some derivatives of anilline or some derivatives of naphthylamine sulfonic acid in proper condition. Their colors are from red to violet. They have excellent tight property. The chemical and physical test of production verified that they were some unique properties.
