A total of 110 arylazo dyes have been prepared, based on five benzenoid and heterocyclic coupling components, and containing combinations of chlorine and sulphonate (sulpho) substituents in the diazo components. Their visibleabsorptionmaxima have been analysed in order to determine the degree to which chloro and sulpho substituentinfluences are constant and transferable, both within a series, and
