It was found that (by coupling diazolated 2-amiilo-IIIiiti-olo # xybeiizole with the urea of the 2-amino-5-oxy-napbtalin-7-sulfo acid we get a correct o-oxyazo substance,

      which dyes cotton in light and alkali-sensitive yellow-pink tones. After copper or even better by dyeing in the manner customary for substantive dyes with the addition of copper compounds to the bath, one can obtain blue-red tones which are light- and alkali-fast.
