Abstract

Procedure for obtaining low solubility diazo compounds, of formula I, **(See formula)** wherein R1 is 1,4- or 1,5-naphthylene or a radical of formula II, **(See formula)** wherein R3 and R4, which may be the same or different, each signify hydrogen, chlorine, bromine, methyl or methoxy, the radicals R2, which may be the same or different, each signify an alkyl radical of 1 to 8 carbon atoms, or the phenyl radical, and the X radicals, which may be the same or different, each mean fluorine, chlorine or bromine, characterized in that 2-hydroxynaphthalene-3-carboxylic acid or a functional derivative thereof, with (i) a compound of formula III, H2N - R1 - NH2 wherein R1 is as defined above, and (ii) a diazonium derivative of a compound, or of compounds of formula IV, **(See formula)** wherein R2 and X are as defined above.
