Abstract

Procedimiento para la obtención de colorantes de cromificación verdescaracterizado porque se copulan ácidos 2-aminofenol-4 o -5-sulfónicos diazotados libres de grupos nitrados queal ser ocupada la 4-posición por el grupo de ácido sulfónicopueden contener en la 5- o 6-posiciónademáshalógeno o grupos alquílicoscon ácido 2-aminonaftalín-3-carbonílico.Procedure for obtaining green chromification dyes characterized in that diazotized 2-aminophenol-4 or -5-sulfonic acids are coupled free of nitrated groups that, when the 4-position is occupied by the sulfonic acid group, can contain in the 5- or 6-position in addition to halogen or alkyl groups with 2-aminonaphthalene-3-carbonyl acid.
