  Additional patent to main patent no. <B> 198710. </B> Process for the production of a disazo dye. According to the method described in the main patent, a disazo dye is obtained which dissolves in organic solvents with a brownish yellow color when p-aminoazobenzene is diazotized and the diazo compound is coupled with p-isohexylphenol.



  'As has now been found further, a disazo dye with similar properties is obtained if one uses 4. 4' <B> - </B> Diamino- 2. 2. <B> 5. </B> 5'-th- # rametl-iyl - # riphenylmethane tetrazotized and the tetrazo compound is coupled with p-isohexylplienol.



  <I> Example: </I> One tetrazotizes at <B> 0 '33 </B> parts 4.4'- Diamino <B> - </B> 2. 2'. <B> 5. </B> Ä '- tetramethyl-triphenyl-methane with the addition of <B> 100 </B> parts of hydrochloric acid, 12 <B>' </B> B6, with <B> 13.8 </B> parts of sodium nitrite and leaves the filtered Solution at <B> 0 '</B> to * a solution of <B> 35.6 </B> parts of p-isohexylphenol, 14 parts of sodium hydroxide and <B> 6 </B> parts of an emulsifying agent. The dye is worked up in the usual way.

   It stains organic solvents in yellow tones.
