  <B>Zusatzpatent</B> zum Hauptpatent Nr. 100705.    Verfahren zur Herstellung eines neuen     indigoiden    Farbstoffes.    Es wurde gefunden, dass man einen neuen       indigoiden        Farbstoff    erhält, wenn man das       4-Chlor-1    .     2-thionaphthisatin,    welches durch  Kondensieren von     4-Chlor-l-thionaphthol    mit       Oxalylchlorid    erhalten werden kann, mit     Oxy-          thionaphtenkarbonsäure    kondensiert.  



       leer    neue Farbstoff bildet ein rotes Pulver,  löst sich in     konz.    Schwefelsäure mit grüner  Farbe und gibt mit     Hydrosulfit    und Natron  lauge eine gelbe     Küpe,    aus welcher Baum  wolle in blauen     Bordeauxtönen    gefärbt wird,  die beim Seifen etwas röter und sehr echt  werden.  



  <I>Beispiel:</I>  In<B>10000</B> Teile Alkohol werden 248,5  Teile     4-Chlor-1    .     2-thionaphthisatiii    und 194  Teile     Oxythionaplitenkarbonsäure    eingetragen    und hierauf längere Zeit am     Rückflusskühler     gekocht. Der gebildete     Farbstoff    wird filtriert,  gewaschen und getrocknet.



  <B> Additional patent </B> to main patent no. 100705. Process for the production of a new indigoid dye. It has been found that a new indigoid dye is obtained if the 4-chloro-1. 2-thionaphthisatin, which can be obtained by condensing 4-chloro-1-thionaphthol with oxalyl chloride, condensed with oxythionaphtenecarboxylic acid.



       empty new dye forms a red powder, dissolves in conc. Sulfuric acid with a green color and with hydrosulphite and sodium hydroxide solution gives a yellow vat, from which cotton is dyed in blue bordeaux tones, which become a little redder and very real when soapy.



  <I> Example: </I> In <B> 10000 </B> parts of alcohol there are 248.5 parts of 4-chloro-1. 2-thionaphthisatiii and 194 parts of oxythionaplitic acid entered and then boiled for a long time on the reflux condenser. The dye formed is filtered, washed and dried.
