Abstract

Inventia se refera la un colorant rosu-galbui direct pentru vopsirea fibrelor celulozice si de amestec, obtinut prin dicuplarea simetrica a 4,4'-diaminobenzanilidei-bis-diazotate cu acidul 1-naftilamino-4-sulfonic si transformarea colorantului în sare de amoniu.The invention relates to a direct red-yellow dyestuff for the dyeing of cellulosic and blended fibers obtained by symmetrically dissociating 4,4'-diaminobenzanilide-bis-diazotate with 1-naphthylamino-4-sulfonic acid and transforming the dye into ammonium salt.
