Abstract

Procedure for preparing water-soluble disazo dyes which, in the form of the free acid, have the general formula: ** (See formula) ** wherein R1 and R2 independently represent hydrogen, halogen, or an alkyl, alkoxy, acylamino, or sulfonic acid group, the hydroxyl group in ring A being in the ortho or meta position with respect to the azo group and E representing the residue of a coupling component of the series aminobenzene, aminonaphthalene, phenol, naphthol, pyrazolone, hydroxypyridone, aminopyrazole, indole or acetoacetarylamide; characterized in that it comprises diazotizing an aminophenolsulfonic acid of the formula: ** (See formula) ** wherein the hydroxyl group is in the ortho or meta position with respect to the amino group, couple the diazo compound with a coupling component of the formula: ** (See formula) ** wherein R1 and R2 are defined as above and then diazotize the aminomonoazoic compound and couple with a coupling component of the series aminobenzene, aminonaphthalene, phenol, naphthol, pyrazolone, hydroxypyridone, aminopyrazole, indole, or acetoacetarylamide.
