      Additional patent to: Main patent no. 245067. Process for the production of a noun azo dye. The subject of the present additional patent is a process for the production of a noun azo dye, characterized in that

       Then you get 2 mol of diazotized 1-oxy-2-aminobenzene-4-carabonsäure-4 '- @ ch @ loTphenyd- amid with 1 mol of the learner condensation product from 1 Mo, l cyanuric chloride @ d @,

      2 moles of amino-5-oxyna! Phthalene-7-sulfonic acid and 1 mole of 1-aminobenzene are combined in an alkaline medium.



  The new dye dyes cotton from weakly al'kalis-ohem baths, to which copper sulfate and sodium tartrate have been added, in real bluish red tones.



  <I> Example: </I> 5'2.4 weighted 1-oxy-2i-aminobenzo. 1-4-carboxylic acid-4'-chlorophenylamide 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 with 6.4,

  6 parts by weight of the learning condensation product from 1 time Cyanur- chlorld, 2 mol 2-Ami.no-5-oxynaph@halin-7- sul'foneäuije and 1 mol 1-aminobenzene, which as the sodium salt with the addition of 200 parts by weight 20 e igem calcium hydroxide were dissolved in 2000 parts by weight of water, combined.

   After 4 shots, the dye formed is separated off by adding hydrochloric acid and filtered. The filter residue is dissolved as the sodium salt. The dye is separated from the solution with common salt,

          filtered and dried. It is a black powder that dyes cotton in a very weakly alkaline bath in red tones. By adding copper sulfate and tartaric acid sodium to the dyebath, the color changes to bluish red. The color is washable and light-proof.
