Abstract

Improvements in the object of the main patent No. 291 121 by "process for preparing diazo dyes of difficult solubility in water", characterized in that disazo dyes of the formula I are synthesized ** (See formula) ** in which A and D each means a radical of the benzene series, and B means an amino group, optionally substituted, an alkoxy group having at least 4 carbon atoms, a cycloalkoxy group, an aralkoxy group or an aryloxy group, optionally substituted on the ring, copulating the diazonic compound of an aminoazoic dye of the formula II ** (See formula) ** in which A and D have the meaning set forth in formula I, with a 1-hydroxynaphthalene compound, coupler in position 2, of formula III ** (See formula) ** in which B has the meaning set forth in formula I, and for this the components are chosen so that the dye does not present water-solubilizing groups that dissociate in water with acidity.
