      Zusatzpatent    zum hauptpatent Nr. 105485.    Verfahren zur Herstellung eines     nachchromierbaren,    grünen     Triphenylmethan-          Azofarbstoffes.       Es     wurde    gefunden, dass     diazotiertes          p-A,mino-o-sulf        o-tetramethyl-p-p-diamino        -tri-          pheny1methan    mit     1-(4'-Oxy-3'-carboxy-5'-          methyl)        -phenyl    - 3 -     methyl-    5     -pyrazolon    zu  einem gelben Farbstoff gekuppelt werden  kann,

   welcher sich in konzentrierter Schwe  felsäure mit gelber Farbe löst, Wolle     aus     saurem     Bada    goldgelb,     nachchromiert    walk-,       potting-    und lichtecht rein grün färbt.  



  <I>Beispiel</I>  42,5 Teile     p-Amino-o-sulfo-tetra,m-ethyl-          p-p-diamino-triphenylmethan    werden     diazo-          tiert    und zu einer     so#cdaalkalisch    gehaltenen  wässerigen Lösung von 25,0 Teilen 1-(4'  Oxy-3'-carboxy - 5' -     methyl)        -phenyl-3-methyl-          5-pyrazolon    gegeben. Es entsteht sofort ein         orangegelber    Brei des     Pyrazolonfarbstoffes,     welcher nach dem     Aussalzen    filtriert, gepresst  und     getrocknet        wird.  



      Additional patent to the main patent no. 105485. Process for the production of a post-chromable, green triphenylmethane azo dye. It was found that diazotized pA, mino-o-sulf o-tetramethyl-pp-diamino -tripheny1methane with 1- (4'-oxy-3'-carboxy-5'-methyl) -phenyl - 3 - methyl- 5 -pyrazolone can be coupled to a yellow dye,

   which dissolves in concentrated sulfuric acid with a yellow color, wool from acidic Bada dyes golden yellow, after-chrome-plated mill-, potting- and lightfast pure green.



  <I> Example </I> 42.5 parts of p-amino-o-sulfo-tetra, m-ethyl-pp-diamino-triphenylmethane are diazo- tated and converted to an aqueous solution of 25.0 parts of 1 that is kept alkaline in this way - (4 'Oxy-3'-carboxy - 5' - methyl) -phenyl-3-methyl-5-pyrazolone given. An orange-yellow paste of the pyrazolone dye is formed immediately, which is filtered, pressed and dried after salting out.

PATENTANSPRUCH: Verfahren zur Herstellung eines nach chromierbaren, grünen Triphenylmeth@anazo- farbstoffes durch Kuppeln von diazotiertem p-Ammo-o-sulf o-tetramethyl-p=p-diamino -tri- phenylmethan mit 1-(4'-Oxy-3'-carboxy-5'- methyl)-phenyl-3-methyl-5-pyrazolon. Der neue Farbstoff löst sich in konzentrierter Schwefelsäure mit gelber Farbe und färbt Wolle aus saurem Badle goldgelb, nachchro- miert walk-, potting- und lichtecht rein grün. PATENT CLAIM: Process for the production of a chromable, green triphenylmeth @ anazo dye by coupling diazotized p-Ammo-o-sulf o-tetramethyl-p = p-diamino-triphenylmethane with 1- (4'-oxy-3 ' -carboxy-5'-methyl) -phenyl-3-methyl-5-pyrazolone. The new dye dissolves in concentrated sulfuric acid with a yellow color and dyes wool from acidic badle golden yellow, after-chroming pure green, fast to walk, potting and light.
