Abstract
Inventia se refera la un colorant brun direct nebenzidinic pentru vopsirea firelor celulozice si de amestec cu rezistente ridicate la tratamente umede si lumina si la un procedeu de obtinere a acestuia prin cuplarea asimetrica a 4,4'-diaminobenzanilidei bis-diazotate cu acidul salicilic, urmata de cuplarea alcalina a diazoazocolorantului format cu complexul de cupru al colorantului obtinut prin cuplarea acidului 2-aminofenol-4-sulfonic diazotat cu rezorcina.The invention relates to a direct nebenzidine brown dye for dyeing cellulose yarns and blending with high resistance to wet and light treatments and to a process for obtaining this by asymmetrical coupling of bis-diazotassium 4,4'-diaminobenzanilide with salicylic acid followed by of the alkaline coupling of the diazoazocolorant formed with the copper complex of the dye obtained by coupling the diazotate-2-aminophenol-4-sulfonic acid with resorcinol.
