Abstract
Colorant stilbenic direct complexat cu cupru, rezistent la lumina, cu nuanta brun, caracterizat prin aceea ca este constituit dintr-un rest de compus monoazoic obtinut prin diazotarea acidului 2-aminofenol-4-sulfonic si cuplare cu m+anisidina cu formula I: (vezi form. in desc.) si o componenta de condensare reprezentata de acidul 4,4'-dinitrostilben-2,2'-disulfonic într-un raport molar compus monoazoic:componenta de condensare de circa 1:0,8. Procedeu de obtinere a unui colorant stilbenic conform revendicarii 1 caracterizat prin aceea ca diazoteaza acidul 2-aminofenol-4-sulfonic cu formula II: cu azotit sodiu în prezenta de acid clorhidric la temperatura de 18....20 degree C si se cupleaya cu m+anisidina cu formula III: (veyi form. in desc.) sub forma de clorhidrat la temperatura de 20....40 degree C în prezenta de acetat de sodiu pentru obtinerea unui colorant monoazoic cu firmula I, care se condenseaza în continuare cu acid 4,4'-dinitristilben-2,2' -disulfonic cu formula IV: (veyi form. in desc.)........
