Abstract
Procedure for the preparation of water soluble disazo dyes of the formula ** (See formula) ** in which X stands for oxygen or sulfur; the benzene nuclei A and D may each be further substituted by halogen or by lower alkyl or lower alkoxy groups; the benzene nucleus B may contain halogen atoms or groups of lower alkyl, lower alkoxy or nitro; and the phenylene radical E may still be further substituted, characterized by coupling the diazonic compound of an amine of the formula ** (See formula) ** in which A, B, D and X have the same meaning as in formula I, with a coupling hydroxybenzene compound in position para with respect to the hydroxylic group and which is eventually substituted in the ring.
