Abstract
Procedure for the preparation of diazo dyes, characterized by coupling 2 moles of a diazo compound of a monocyclic or bicyclic amine with a coupling component of the formula **(See formula)** in which X is a hydroxylic group or, preferably, an amine group; R1 and R2 are each a hydrogen atom, an aryl radical, an alkoxy radical and, in particular, an alkyl radical; and when X = OH, also a carboalkoxy or carbonamidic radical; R3 and R4 signify alkyl or alkoxy groups, halogen atoms, and in particular hydrogen atoms, and Z means an oxygen or sulfur atom or an organic radical devoid of off-chain oxygen atoms, * and, optionally, quaternized when the D1 and/or D2 radicals have quaternizable nitrogen atoms.
