Kamel, M. published the artcileHeterocyclic azo dyes. V. Further studies on azo dyes containing a benzothiadiazole ring, HPLC of Formula: 1753-29-3, the publication is Kolorisztikai Ertesito (1976), 18(5-6), 155-61, database is CAplus.
Disperse and acid dyes were prepared by coupling 5-hydroxy-1,2,3-benzothiadiazole (I) [7686-40-0] with various aromatic amines, and their dyeing and fastness properties on nylon 66 or wool were determined The disperse dyes showed poor affinity for nylon (except at high temperature) in contrast to corresponding dyes from 5-amino-1,2,3-benzothiadiazole which have good affinity; the latter dyes also show better light- and washfastness. All the acid dyes, prepared by coupling I with diazotized naphthylamine sulfonic acids, showed good affinity for wool and good leveling properties; light- and washfastness were 2-3 and 3-4, resp.
