    oder ist ein Gemisch dieser beiden Stoffe.  Er färbt Wolle aus saurem Bade in blau  stichig roten Tönen, die durch     Nachchromie-          ren    bedeutend an Echtheit     gewinnen;    bei  dem Chromdruck auf Baumwolle und Kunst  seide wird ein sehr     klares    blaustichiges Rot  von sehr guten     Echtheitseigenschaften    er  halten.



  <B> Additional patent </B> to main patent no. 19871.3. Process for the preparation of an honorable dye of the triarylmethane grater. The subject of this additional patent is a process for the preparation of a chromable dye of the triarylmethane series, which is characterized in that N- (3-Ogypheny)

  -morpholine condensed with 5-ogytrimellitic anhydride.



  <I> Example: </I> 9, parts by weight of N- (3-ogyphenyl) morpholine of the formula
EMI0001.0021
    (colorless substance with a melting point of <B> 1131 </B> to <B> 132 '</B> C, obtainable by condensation of norpholine and resorcinol) and 15 parts by weight of 5-Ogytrimellitlisäure- anhydride are 4 stuxides with stirring to 180 190'C heated.

   After cooling, the finely powdered melt is divided into 500 parts. 25% hydrochloric acid dissolved with gentle heating and stirring, the red dye solution .through a glass filter; sucked and from: the red filtrate precipitated the dye by adding twice the volume of water.

    It is suctioned off, washed neutral against the Congo with cold water and dried. The dye has the constitution:
EMI0001.0056
    
EMI0002.0001
    or is a mixture of these two substances. He dyes wool from an acid bath in blue, pungent red shades, which gain significantly in authenticity through re-chrome plating; With the chrome print on cotton and artificial silk, a very clear blue-tinged red with very good fastness properties is obtained.
