      Additional patron to main patent no. <B> 180057. </B> Process for the production of an azo dye. It has been found that a new azo dye is obtained if <B> 1 </B> mole of cyano-nitride, <B> 1 </B> mole of 1,4-oxy-amino-anthraellinone, 5-sulionic acid,

     <B> 1 </B> mol of the monoazo dye from <B> 1 </B> mol of diazotized 1-i-methoxy-2-amino-4-benzenesulphonic acid and <B> 1 </B> mol of 2-amino-5 -oxynaphthalene-7-sulfonic acid and <B> 1 </B> mol of aniline act on one another in such a way that

          that <B> every 1 </B> halogen atom of the cyanuric fluoride is replaced by <B> every 1 </B> mol of the three other starting materials.



  The new dye forms a dark powder that dyes cotton and viscose silk in clear yellow-tinged red tones. <I> Example: </I> A suspension of <B> 18.5 </B> parts of cyanuric chloride in <B> 500 </B> parts of water is given a neutral solution of <B> 31.9 </ B> Parts of 114-oxy-amino-anthraeliinone-5-sulfonic acid in 1200 parts of water. The mixture is stirred for 4 to <B> 5 </B> hours at la <B> '</B> and the reaction is kept neutral by adding sodium carbonate solution.

    45.3 parts of the monoazo dye from diazotized 1-methoxy-2-amino-4-benzenesulfonic acid and 2-amino-5 are added / B> oxynaphthalene-7-sulionic acid at 40 ', stir until the condensation is complete and the hydrochloric acid formed is neutralized at the same time, then add 18 g aniline, stir for 2 hours at 90 </B> to <B> 95 </B> ', and salt out the dye.
