  <B> Additional patent </B> to main patent no. 232121. Process for the production of a urea derivative. It has also been found that a new urea derivative can be obtained which at the same time: represents a western full azo dye if 2-methyl-4- (3 "- amina) -benzoyl.amino-4 '-ogy- @ 1,1' - @ azabenzol- a'-carboxylic acid-5 '= suIfo:

  Nisäure 1 mole of phosgene c can act.



  The new dye is a light brown powder, which dyes cotton in a weakly alkaline bath to which a copper salt solution of copper sulfate and tartrate of sodium has been added in a washable, greenish yellow shade.



  <I> Example: </I> 70.2 parts by weight of the mon: oazofarbsto: ffes from diazotized 1-amino-4-, oxyblenzene-3-carbo-oxy-5-sulfone # lure and 1-methyl-3 = aminobic! Enz: ol are: dissolved as Na salt with the addition of 27 parts by weight of sodium acetate in 500 parts by weight of water.

   This solution winds up at around. <B> 60 '</B> treated with 39 parts by weight of 3-I \ titrobenzoyl chloride: to which 10 parts by weight of acetone were added. Man reduces the formed nitrobenzo:

  yl product with 84 parts by weight of crystallized sodium sulfide, which were dissolved in 150 parts by weight of water, at 65-70 to the amine. o: benzoyl product. The separated reduction product is with the addition of sodium carbonate: until the @deutliehen alkaline reaction in 4000:

          Parts by weight of water dissolved and treated with phosgene for 24 hours with stirring at 3: 0-40; until no free NHZ group, e: can be detected anymore. The urea derivative obtained from @ is precipitated as the sodium salt, filtered and dried.
