  <B> Additional patent </B> to main patent no. <B> 245067. </B> 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 by the fact that 2 moles of diazotized 1. - oxy-2-aminob:

  enzene-4-, carboxylic acid-1'-nap'h-thylamide with 1 mol of the ternary condensation product from 1 time cyanuric chloride, 2 mol of 2-amino-5-oxynaphthalene-7-sulphonic acid, and 1 mol 1-aminobenzene combined in an universal medium.



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



  <I> Example: </I> 55.6 parts by weight of 1-oxy-2-aminodbenz.ol- 4-carbon-acid-1'-nap, 'hthy @ lamid are added with the addition of 14 parts by weight of sodium nitrite and 54 parts by weight of concentrated hydrochloric acid 0 dianotated and the diazo compound with 64,

  6 parts by weight of the ternary condensation product of 1 mole of cyanuric chloride, 2 moles of 2-amino-5-oxynaphthalene-7-sulfonic acid and 1 mole of 1-aminobenzal, which is the sodium salt with the addition of 2;

  00 parts by weight of 20% calcium hydroxide were dissolved in 2000 parts by weight of water,

         united. After 4 hours the dye formed is separated off by adding hydrochloric acid and filtered. The filterwAstand is dissolved as the sodium salt. The dye is separated from the solution with coconut oil,

   filtered and dried. It steals an e-black powder that dyes cotton in a weakly alkaline bath in red tones. When the dyebath is mixed with a copper solution of copper sulfate and acidic sodium, the color changes to a bluish red.

   The color is washable and lightfast.
