      Additional patent to main patent No. 226692. Process for the production of an acidic wool dye. The present patent relates to a process for the production of an acidic wool dye, thereby .gekenn, z @ eichne @ t "that the 1-amino-4-bro @ m:

  a @ nthraquinone-2-sulphonic acid with 3-amünobenzyl- (benzyl, anvioline-4'-sudfonic acid) of the formula
EMI0001.0013
         condensed. The dyestuff obtained dyes wool in clear, reddish-blue shades of good lightfastness and good water-fastness properties with sufficient easiness.



       Example: 40 TeiMia, the sodium salt of 1-amiroo-4-bromanthraquinone-2-sulfonic acid, are dissolved in about 2,000 parts of Waoseir with the addition of 50 parts of sodium bicarbonate. After adding 60 parts of 3 - aminobenzyl - (benzyl-anik # n-4'-sulfone:

  acid) of the formula
EMI0001.0042
    and 5 parts of copper chloride is heated for several hours in an elusive water bath. When the dye formation is over,

   is filtered and the dye formed is salted out. It is conveniently cleaned by de-ironing from water.
