  Additional patent to main patent; No. <B> 217493. </B> Process for the production of a pimple dye. The present patent relates to a process for the production of a vat dye, characterized in that

       that 2 moles of a mixture of 1-aminoanthraquinone-6-earboyl-l'-aminoanthraquinone and <B> 1 - </B> aminoanthraquinone <B> -7 - </B> earboyl <B> - l'- </B> amineo - anthraquinone with <B> 1 </B> Mol 6-Bz, -dibromobenzanone. condensed and the condensation product obtained is heated with an alkali hydroxide in the presence of an inert solvent.



  The vat dye obtained in this way dissolves in concentrated sulfuric acid with a green color <B> and </B> dyes cotton from a brown-black vat in real olive tones. <I> Example: </I> 20 parts of 6-Bz, -Dibromobenzanthron who with 48 parts of 1-aminoanthraquinone-6- resp. -7-earbciyl-I'-aminoanthraquinone condensed by heating for 16 hours in nitrobenzene in the presence of sodium carbonate and copper chloride as a catalyst.

   The condensation product dissolves in brown-centered sulfuric acid and dyes cotton from a violet-brown vat in brown tones.



  20 parts of the termination product are finely divided with a solution of 20 parts of Ätzhali in <B> 150 </B> parts of aminoethano # 1 for about <B> 2-3 </B> hours for <B> 110 ' C </B> he heats up. The dye formed is deposited by adding water and blowing air into it.
