      Additional patent to main patent No. 198713. Process for the preparation of a chromable dye of the triarylmethane series. The subject of this additional patent is a process for the production of a chromable dye of the trarylmethane series, which is characterized in that

          meow -4-diogybenzoic acid with 1 -, (4'-dimethylamino-2'-ogybenzoyl) -o-ogy-, carbogy = 2-benzoic acid, which is formed by condensation of dimethyiamino-m-phenol with 5- Oxytrimellitic anhydride is available at 1.5-140 C, condensed.

      <I> Example: </I> 3.4 parts by weight of 1- (4'-dimethylamino-2'-oxy-benzoyl) -oxy-, earboxy-2: -benzoic acid (obtained by condensation of dimethylamino-m-phenol with 5 -Ogytrimellitic anhydride is available at 1.3,5-140 ° C). And 1-6 parts by weight of 2,4-diogybenzoic acid are pulverized together, in 1200 parts by volume of sulfuric acid (95%)

      .dissolved and heated to <B> 90'C </B> for about 8 hours. After cooling, water is added to about 3000 parts, the dye which has separated out is filtered off with suction, washed neutral and dried.

   It represents a red powder and dyes wool from an acid bath in a very clear red, which: when recliromised, becomes a little more bluish and its fearfulness is considerably improved.
