Abstract
Inventia se refera la un colorant brun-violet direct cuprabil pentru vopsirea rezistenta, dupa cuprare, a firelor celulozice si la un procedeu de obtinere a cestora, prin cuplarea asimetrica a 4,4'-diamino-3,3'-dimetoxidifenilului bis-diazotat cuacidsalicilic, urmata de cuplarea intermediarului format cu un colorant monoazoic, obtinut prin monocuplarea acidului 2-aminofenol-4-sulfonic cu rezorcina.
