      Zusatzpatent        zum        Hauptpatent        Nr.   <B>210831.</B>    Verfahren zur Herstellung eines     ehromierbaren        Farbstoffes    der     Triarylmethaureihe.       Gegenstand dieses Zusatzpatentes ist ein  Verfahren zur Herstellung     eines        chromier-          baren    'Farbstoffes der     Triarylmethanreihe,     welches dadurch gekennzeichnet ist, dass man       1-(4'-Diäthylamino-2'-oxybenzoyl)-o-oxycarb-          oxy-2-benzoesäure,

      die durch Verschmelzen  von 5 -     Oxytrimellitsäureanhydrid        mit        Di-.          äthylamino-m-phenol    während mehrerer Stun  den bei     etwa    120 bis<B>130'</B> C erhältlich ist,       mit    dem aus     diazotiertem        o-Aminophenol    und       Resorcin    erhältlichen     Azofarbstoff    konden  siert.  



       Beispiel:     7,4 Gewichtsteile des salzsauren Salzes der       1-(4'-Diäthylamino-2'-oxybenzoyl)-o-oxycarb-          oxy-2-benzoesäure,    die durch Verschmelzen  von     5-Oxytrimellitsäureanhydrid    mit     Diäthyl-          amino-m-phenol    während mehrerer     Stunden     bei etwa 120 bis 130   C erhältlich ist, und  4,3 Gewichtsteile des     Azofarbstoffes,    der  durch     Diazotieren    und Kuppeln von     o-Amino-          phenol    auf     Resorcin    entsteht,

       werden    in 40         Volumteilen    konzentrierter Schwefelsäure  4 bis 5     Stunden    bei 90   C kondensiert. Man  erhält einen Farbstoff, der sauer gefärbt     ein     stumpfes Violett ergibt, das     beim        Nach-          chromieren        etwas        rotstichiger    und in den  Echtheitseigenschaften verbessert     wird.  



      Additional patent to main patent no. <B> 210831. </B> Process for the production of an honorable dye of the triarylmetha series. The subject of this additional patent is a process for the production of a chromable 'dye of the triarylmethane series, which is characterized in that 1- (4'-diethylamino-2'-oxybenzoyl) -o-oxycarboxy-2-benzoic acid,

      by fusing 5 - oxytrimellitic anhydride with di-. Ethylamino-m-phenol is available for several hours at about 120 to <B> 130 '</B> C, condenses with the azo dye obtainable from diazotized o-aminophenol and resorcinol.



       Example: 7.4 parts by weight of the hydrochloric acid salt of 1- (4'-diethylamino-2'-oxybenzoyl) -o-oxycarboxy-2-benzoic acid, obtained by fusing 5-oxytrimellitic anhydride with diethylamino-m-phenol during several hours at about 120 to 130 C, and 4.3 parts by weight of the azo dye, which is formed by diazotizing and coupling o-aminophenol on resorcinol,

       are condensed in 40 parts by volume of concentrated sulfuric acid at 90 C for 4 to 5 hours. The result is a dye which, when dyed with acid, gives a dull violet, which is somewhat reddish in color when it is chromed and its fastness properties are improved.
