Abstract

Procedure for the preparation of hardly water-soluble disazo dyes of the formula I **(See formula)** in which R stands for a phenyl radical optionally substituted by halogen, lower alkyl or lower alkoxy groups, X stands for oxygen or sulfur, Q means the radical of a benzene or naphthalene compound, possibly substituted by halogen, lower alkyl or lower alkoxy groups in which the nitrogen bonds are found in position 1 and 4, B a phenyl radical optionally further substituted, showing the hydroxy group in the ortho position or for the azo group, and the benzene nucleus A may still be substituted, characterized in that the diazonium compound is coupled from an aminoazo compound of the formula **(See formula)** in which R, X, A and Q have the meanings indicated under formula I, with a hydroxybenzene compound optionally substituted in the ring that has an ortho position or for the hydroxyl group, for which the starting materials are chosen, so that the final product does not show water-soluble groups of acid dissociation in water.
