  Additional patent to main patent no. <B> 198713. </B> Process for the production of an honorable dye of the triarylmethane series. The subject of this additional patent is a process for the production of an honorable dye of the triarylmethane series, which is characterized in that W-diethylamino AY-oxy)

     <B> - 1 - </B> benzoyl <B> - </B> o <B> - </B> oxy-earboxy-2-benzoic acid, which dureli condensation of dietliylamino-m-phenol with 5-oxytrimellitic anhydride at 125-130 '<B> C </B>, condensed with 2.4.6-tribromobesorein.



  <I> Example: </I> 41 parts by weight (4'-diethylamino-2'-oxy) -1-benzoyl-o-oxycarboxy-2-benzoic acid, which is obtained by condensation of diethylamino-m-phenol with 5-oxtrimellitic acid - anliydride is available at 125-130 ° C, are 34,

  7 parts by weight of 2.4.6-Tribromresorein in <B> 250 </B> parts by weight of 95% strength sulfuric acid heated to <B> 100 ° C </B> for 10-20 hours and sucked off warm through a gas duct. The dye is precipitated by adding ice to the sulfuric acid solution. It is vacuumed and dried. For further purification, the dye can be stirred out with concentrated hydrochloric acid, which causes it to dissolve. After suctioning off the residue, precipitating it from the salt-acid solution by adding water, a red powder is obtained.

   After transferring into the sodium salt, a soluble dye is obtained which colors the animal fiber in a bright red tone, which is only slightly changed by chromium plating. The fastness properties are then excellent, including the light fastness.
