Abstract
Inventia se refera la un procedeu de obtinere a colorantului negru complex Cr 2 : 1 acid 6-nitro-1-diazo-2-naftol-4-sulfonic - 2-naftol în care colorantul obtinut în urma reactiei de cuplare efectuata în prezenta de eter-sulfat de nonilfenol etoxilat, în calitate de agent tensioactiv si de alcool 2-etilhexilic în calitate de agent antispumant, se complexeaza în acelasi mediu de reactie, fara separare, prin tratare cu o solutie apoasa a unei sari de Cr III sau de Cr VI în prezenta unui agent reducator, dupa care colorantul metalizat se izoleaza din masa de reactie la pH acid, cu NaCl.
