Abstract

Improvements in the object of the main patent No. 237,574 by a process for the manufacture of new azo dyes, characterized in that they are prepared by condensation or coupling disazo dyes corresponding, as free acids to the formula ** (See formula) ** in which X means a hydrogen atom or a sulfonic acid group, D1 means a phenyl or naphthyl radical, free of nitrogen atoms, containing at least one sulfonic acid group and/or a carboxylic acid group, and Y means a heterocyclic reactive substituent.
