  Process for the production of a subatantive azo dye. The subject matter of the present additional patent is a process for the production of a subatantive azo dye, characterized in that

      that 2 moles of diazotized 1- oxy- 2- amindbenzene-4-carboxylic acid phenyl amide with 1 Mül of the ternary condensation product of 1 mole of Cyanurohlori @ d, 2 moles of 2 - amino-5-oxynaphthalene-7-sulfonic acid and 1-aminobenzene combined in an alkaline medium.



  The new dye dyes cotton from a weakly alkaline bath to which copper sulfate and sodium tartrate have been added in real bluish red tones.



  <I> Example: </I> 45 "; 6 parts by weight of 1, oxy-2-arninobenzene- 4-, carbonic acid plienylamide are diazotized at 0 with the addition of 14 parts by weight of sodium nitrite and 54 parts by weight of concentrated hydrochloric acid and the diazo compound is diazotized with 64, 6 parts by weight of the learning condensation product,

      from 1 mole of cyanuric chloride, 2: mole of '21 -Aimlno-5-, oxynapbtholine-7-ssulfonic acid and 1 mole of 1-aminobenszene, which is obtained as sodium sa7.z with the addition of 2100 parts by weight of 2.0% calcium hydroxide in 21000 Part of the water has been dissolved,

   united. After 4 hours, the dye formed is deposited by adding hydrochloric acid and filtered. The filter residue is dissolved as sodium salt. Out. The dye is removed from the solution with common salt, filtered and dried.

   It is a black powder that dyes cotton in a black alkaline bath in red tones. By adding a copper salt solution of copper sulfate and tartrate of sodium to the dyebath, the color changes to a bluish red. The coloring is washable and fast-drying.
