  Verfahren zur Herstellung neuer     Anthrachinonfarbstoffpigmente       Es wurde gefunden, dass man zu wertvollen     Anthra-          chinonfarbstoffpigmenten    der Formel  
EMI0001.0004     
    gelangt,     worin    Y ein     Wasserstoff-    oder Chloratom be  deutet, wenn man ein     Phenyldihalogentriazin    der Formel  
EMI0001.0008     
    mit einem     Anthrachinon    der Formel  
EMI0001.0010     
    im     Molverhältnis    1:2 kondensiert. Man geht     zweckmäs-          sig    vom     2-(4'-Chlorphenyl)-4,6-dichlor-1,3,5-triazin    aus.  



  Als     Aminoanthrachinone    kommen das     1-Amino-          anthrachinon    und das     1-Amino-6-chloranthrachinon    in  Betracht.  



  Die Kondensation erfolgt zweckmässig in einem     iner-          ten    organischen Lösungsmittel, beispielsweise     Nitroben-          zol,    Chlorbenzol,     o-Dichlorbenzol    oder Naphthalin bei  erhöhten Temperaturen, d. h. vorteilhaft zwischen 90  und 210 , nötigenfalls unter Zugabe kondensierend wir  kender Mittel, beispielsweise     Kupferchlorür    und/oder  säurebindender Mittel.  



  Die verfahrensgemäss erhaltenen Farbstoffe eignen  sich zum Färben und Bedrucken der verschiedensten  Materialien, wie synthetischen oder natürlichen Fasern,  beispielsweise aus     Celluloseestern,    Polyestern, insbeson  dere     Polyäthylenterephthalaten,    Polyamiden, Polyacryl  nitril,     Polyvinylchlorid,    Wolle, Seide und insbesondere  zum Färben und Bedrucken von Textilmaterialien aus  natürlicher oder regenerierter     Cellulose    aus der     Küpe.     



  Die mit den erfindungsgemässen Farbstoffen erhal  tenen Färbungen zeichnen sich durch ausgezeichnete  Licht- und     Nassechtheiten    aus.  



  Die neuen Farbstoffe stellen auch sehr wertvolle  Pigmente dar, welche für die verschiedensten Pigment  applikationen verwendet werden können, so z. B. in  feinverteilter Form zum Pigmentieren hochmolekularer  organischer Verbindungen, wie Viskose,     Celluloseäther     und     -ester,    Superpolyamide,     Superpolyurethane    oder  Polyester in der Spinnmasse, Lacke oder Lackbildner,  Lösungen und Produkte aus     Acetylcellulose,        Nitrocellu-          lose,    natürlicher Harze oder Kunstharze, wie     Polymeri-          sationsharze    oder Kondensationsharze, z.

   B.     Amino-          plaste,        Alkydharze,        Phenoplaste,        Polyolefine,    Polyäthy  len,     Polypropylen    oder Polystyrol sowie     Polyvinylchlo-          rid,        Polyacrylnitril,    Gummi, Casein, Silikon und Silikon  harze.  



  Im nachfolgenden Beispiel bedeuten die Teile, so  fern nichts anderes angegeben wird, Gewichtsteile, die      Prozente Gewichtsprozente, und die Temperaturen sind  in Celsiusgraden angegeben.  



  <I>Beispiel</I>  Eine Mischung von 7,6 Teilen     1-Aminoanthrachinon,     4,3     Teile        2-(4'-chlorphenyl)-4,6-dichlor-1,3,5-triazin    und  124     Vol.-Teilen    Nitrobenzol wird allmählich auf 120        erwärmt,    3     Stunden    bei dieser Temperatur gerührt, da  nach auf l60      erwärmt    und 2 Stunden bei 160  gerührt._  Der in gelben     Mikroblättern    kristallisierende Farbstoff  wird bei 120      abfiltriert    und gegebenenfalls mit Nitro  benzol ausgekocht, nochmals     abfiltriert,    mit Alkohol ge  waschen und getrocknet.

   Er färbt     Polyvinylchlorid    in  gelben Tönen von ausgezeichneten     Echtheiten.     



  Verwendet man anstelle des     1-Aminoanthrachinons     das     1-Amino-6-chloranthrachinon,    so gelangt man zu  einem Farbstoff mit ähnlichen Eigenschaften.



  Process for the production of new anthraquinone dye pigments It has been found that valuable anthraquinone dye pigments of the formula
EMI0001.0004
    arrives, in which Y is a hydrogen or chlorine atom, when using a phenyldihalotriazine of the formula
EMI0001.0008
    with an anthraquinone of the formula
EMI0001.0010
    condensed in a molar ratio of 1: 2. It is appropriate to start from 2- (4'-chlorophenyl) -4,6-dichloro-1,3,5-triazine.



  As aminoanthraquinones, 1-aminoanthraquinone and 1-amino-6-chloroanthraquinone come into consideration.



  The condensation is expediently carried out in an inert organic solvent, for example nitrobenzene, chlorobenzene, o-dichlorobenzene or naphthalene at elevated temperatures, ie. H. advantageously between 90 and 210, if necessary with the addition of condensing agents, for example copper chloride and / or acid-binding agents.



  The dyes obtained according to the process are suitable for dyeing and printing a wide variety of materials, such as synthetic or natural fibers, for example made of cellulose esters, polyesters, in particular polyethylene terephthalates, polyamides, polyacrylic nitrile, polyvinyl chloride, wool, silk and especially for dyeing and printing textile materials made of natural or regenerated cellulose from the vat.



  The dyeings obtained with the dyes according to the invention are distinguished by excellent light and wet fastness properties.



  The new dyes are also very valuable pigments that can be used for a wide variety of pigment applications, such. B. in finely divided form for pigmenting high molecular weight organic compounds such as viscose, cellulose ethers and esters, super polyamides, super polyurethanes or polyesters in the spinning mass, lacquers or lacquer formers, solutions and products made from acetyl cellulose, nitrocellulose, natural resins or synthetic resins such as polymer sationsharze or condensation resins, z.

   B. Amino- plastics, alkyd resins, phenoplasts, polyolefins, Polyäthy len, polypropylene or polystyrene and polyvinyl chloride, polyacrylonitrile, rubber, casein, silicone and silicone resins.



  In the following example, unless otherwise specified, the parts are parts by weight, the percentages are percentages by weight, and the temperatures are given in degrees Celsius.



  <I> Example </I> A mixture of 7.6 parts of 1-aminoanthraquinone, 4.3 parts of 2- (4'-chlorophenyl) -4,6-dichloro-1,3,5-triazine and 124 vol. Parts of nitrobenzene is gradually warmed to 120, stirred for 3 hours at this temperature, since after warmed to 160 and stirred for 2 hours at 160._ The dye which crystallizes in yellow microleaves is filtered off at 120 and optionally boiled with nitrobenzene, filtered again with alcohol ge wash and dry.

   It dyes polyvinyl chloride in yellow shades with excellent fastness properties.



  If 1-amino-6-chloroanthraquinone is used instead of 1-aminoanthraquinone, a dye with similar properties is obtained.
