    • Abstract

       

      The 5-hydroxycoumarins behave very similar to 7-hydroxycoumarins in regard to azo-dye formation with one and more than two molecular proportions of diazotisedp-nitraniline. The significance of these results is discussed.

      The authors desire to express their grateful thanks to Prof. T. R. Seshadri for his kind interest in this work.
