Abstract
A procedure for preparing sulfonated azo dyes represented by the general formula **(See formula)** in which A represents: **(See formula)** characterized in that 4,4'-diamino-benzanilide is tetraazoted, and the resulting tetrazoic derivative is reacted with 2-amino-8-naphthol-6-sulfonic acid in a substantially acidic medium followed by reaction in a substantially alkaline medium, with phenol, with 8-amino-1-naphthol-3,6-disulfonic acid or with 2-amino-5-naphtho1-7-sulfonic acid to link the appropriate group A.
