Abstract

Procedure for the production of disazo dyes containing sulfonic acid groups, of formula I, **(See formula)** wherein the Xs each stand for a halogen atom, R1 stands for a hydrogen or halogen atom, or a nitro, hydroxy, -SO3H, alkyl or alkoxy group, or an alkylated or acylated amino group, and R2 stands for a hydrogen atom or a hydroxy, alkyl, alkoxy or -SO3H group; characterized by the coupling of a diazotized amine which, in the form of free acid, corresponds to formula II, **(See formula)** wherein R1, R2 and X are as defined above, with a coupling component which, in the form of free acid, corresponds to formula III, **(See formula)** in a neutral to acidic medium.
