Abstract

Procedure for obtaining azo dyes derived from dibenzofuran, of the formula: **(See formula)** where R is the radical of a coupling component, R1 is the radical of a coupling component other than R, and n is an integer from 1 to 8, and aromatic rings A and/or B may or may not be substituted by a normal substituent in the field of azo chemistry, and the sulfonic acid group, or groups, may be present in the A or B rings, or in the R or R1 radicals, characterized in that it comprises coupling a tetrazoic compound of a diamine, of formula Ia, **(See formula)** wherein rings A and B are defined as above, with a coupling component, of formula Ib, R - H Ib where R is defined as above, and with a coupling component, of formula Ic, R1 - H Ic where R1 is defined as above.
