  <B> Additional patent </B> to main patent no. 200369. Process for the production of a vat dye. The present patent relates to a process for the production of a vat dye, characterized in that a functional derivative of diphenyl-azogy-diphenyl-4,4'-,

  dicarboxylic acid condensed with 1-amino-5-benzoylaminoanthraquinone in a molecular ratio of 1: 2.



  The dye thus obtained dissolves in concentrated sulfuric acid with a dark red color and dyes cotton from a violet vat in red-embroidered, tanned shades with excellent fastness properties. <I> example:

  </I> In a solution of 35 parts of 1-amin.o-5-benzoyl.- aminoauthraquinone in about 500 parts of monochlorobenzene, kept at 100 to 120 ° C., 24 parts of diphenyl azogy -idip.henyl-4,

  4'-dicarboxylic acid dichloride and then boil for about 1 hour with stirring and reflux cooling. The dye formed is then sucked off, washed and dried.



  The acid dichloride used, which has the following formula. comes to:
EMI0001.0055
    has a melting point of 19-2 ° C. The corresponding dicarboxylic acid can be reduced by reduction. obtained from 4-nitrodiphenyl-4 ', carboxylic acid with grape sugar.
