  Zusatzpatent zum Hauptpatent     Nir.   <B>115703.</B>    Verfahren zur Herstellung eines neuen     inetallhaltigen    Farbstoffes.    Es wurde gefunden,     dass    man einen neuen       niefallhaltigen    Farbstoff erhält, wenn man  das     Kupplungsprodulzt    aus     diazotierter        2-          Aniino-l-oxynaphilialin-4,8-disulfosäure    und       ,#--1,8-iiaphthalsäure    mit Kupfersulfat       3-0x-          behandelt.    Der neue metallhaltige     Farbstoff-          bildet    ein dunkles Pulver,

   löst sieh in Was  ser mit violetter Farbe und erzeugt auf  Wolle, ans saurem Bade gefärbt, echte vio  lette Töne.    <I>Beispiel<B>:</B></I>  64,9 Teile des Farbstoffes aus der     Dia-          zoverbindung    der     2-Amino-l-oxynaphtlialiii-          4,8-disulfosäure        und        3-Oxy-1,8-naphthalsäiire     werden in 2000 Teilen Wasser kochend ge  löst.

   Hierauf setzt man dieser     Lösling   <B>21</B>  Teile     Kupfersuliat,    gelöst in<B>300</B> Teilen  heissem Wasser, zu und kocht das Gemisch    noch einige Zeit weiter, indem die frei  ,gewordene Mineralsäure mit     Natriumaeetat     <B>D</B>  abgestumpft wird. Der     klipferhaltige    Farb  stoff -wird hernach durch Zusatz von Koch  salz gewonnen.



  Additional patent to the main patent Nir. <B> 115703. </B> Process for the production of a new metal-containing dye. It has been found that a new dyestuff which does not contain any cases is obtained if the coupling product of diazotized 2-amino-1-oxynaphilialin-4,8-disulfonic acid and, # - 1,8-iaphthalic acid is treated 3-0x- with copper sulfate. The new metal-containing dye - forms a dark powder,

   Dissolves in water with a violet color and produces real violet tones on wool dyed in an acid bath. <I> Example<B>:</B> </I> 64.9 parts of the dye from the diazo compound of 2-amino-1-oxynaphtlialiii- 4,8-disulfonic acid and 3-oxy-1,8- naphthalic acids are dissolved in 2000 parts of water at the boil.

   This solubility is then added to <B> 21 </B> parts of copper sulate, dissolved in <B> 300 </B> parts of hot water, and the mixture is boiled for some time by mixing the released mineral acid with sodium acetate > D </B> is blunted. The dye, which contains clippers, is then obtained by adding cooking salt.
