  Process for the preparation of a condensation product of the anthraquinone series which can be used as a dye and dye intermediate. It has been found that a new condensation product of the anthrachinone line which can be used as a dye and dye intermediate product is obtained if cyanuric acid is used. chloride and <B> 1 - </B> 5-Diaminoalitlir-, tehiiioii reacts with one another,

   namely under application, (, y- from at most one molecule of the latter to <B> each </B> one molecule of the former.



       Example: 24 parts of <B> 1 - </B> 5-diaminoanthraquinone are mixed with <B> 36 </B> parts of cyanuric chloride for about <B> - /, </B> hours in nitrobenzene to reach you this heated. After cooling, the precipitated xondensation product is separated from the nitrobenzene mother liquor, washed nitrobenzene-free with aluminum alcohol, further cleaned and dried if necessary.

   It is a dark-yellow powder, is soluble in water, contained in and hot alcohol, white, soluble in contained, somewhat more soluble in nifroberizole with a brownish-yellow color.

    The solution in concentrated, cold seliweel acid is <B> yellow </B> to brown, the solution of the product that has been hipened is brittle .; Cotton hates itself. color it in reddish-yellow tones.
