Das Färben von Polystyrol in der Masse stellt an die zu verwendenden Farbstoffe hohe Ansprüche. So wird verlangt, daß die Farbstoffe unter den hohen Temperaturen, bei denen Polystyrol verarbeitet wird, beständig sind. Sie müssen deshalb eine Temperaturstabilität von mindestens 200° C besitzen. Außerdem sollen sich die Farbstoffe beim Einarbeiten in die Polystyrolmasse leicht verteilen und dabei gut reproduzierbare gleichmäßige Färbungen von hoher Lichtechtheit liefern.The dyeing of polystyrene in the mass places high demands on the dyes to be used. So it is required that the dyes under the high temperatures at which polystyrene is processed, are persistent. They must therefore have a temperature stability of at least 200 ° C. Besides that the dyes should be easily distributed when incorporated into the polystyrene composition and should be easily reproducible deliver uniform colorations of high lightfastness.

Die meisten der bekannten Farbstoffe erfüllen diese extremen Anforderungen nicht. Azofarbstoffe zersetzen sich in der Regel bei den hohen Temperaturen und genügen meistens nicht in der Lichtechtheit. Anorganische Pigmente lassen sich in Polystyrol nicht immer gleichmäßig verteilen und erfordern eine hohe Dispergierarbeit. Auch sind bekanntlich sowohl der Farbton als auch die Farbstärke der mit anorganischen Pigmenten erhältlichen Färbungen unbefriedigend, insbesondere bei transparenten Färbungen.Most of the known dyes do not meet these extreme requirements. Azo dyes usually decompose at the high temperatures and are usually not sufficient in terms of lightfastness. Inorganic pigments cannot always be evenly distributed in polystyrene and are required a high work of dispersion. It is also known that both the hue and the color strength are with Inorganic pigments obtainable in colorings are unsatisfactory, especially in the case of transparent ones Colorations.

Erfindungsgegegenstand ist die Verwendung von 1,4-Dihydroxyanthrachinonderivaten, die in Nachbarstellung zu einer Hydroxygruppe ein Halogenatom, eine Aminogruppe oder einen Alkyl-, Aryl-, Aralkyl-, Alkylamino-, Arylamino-, Aralkylamine-, Acylamino-, Alkoxyalkylamino-, Hydroxyalkylamino- oder Hydroxyalkylmercaptorest enthalten, für das Färben von Styrolpolymerisaten in der Masse.The subject of the invention is the use of 1,4-dihydroxyanthraquinone derivatives, which are in the adjacent position to a hydroxy group a halogen atom, an amino group or an alkyl, aryl, Aralkyl, alkylamino, arylamino, aralkylamine, acylamino, alkoxyalkylamino, hydroxyalkylamino or Hydroxyalkylmercaptorest contain, for the dyeing of styrene polymers in the mass.

Diese Farbstoffe sind bekannt. Nach den Angaben der schweizerischen Patentschrift 374 964 kann man sie zum Färben von Polyolefinfasern aus wäßrigem Bad verwenden. Es ist deshalb überraschend, wenn nun gefunden wurde, daß die nach der Erfindung zu verwendenden Farbstoffe die für die Massefärbung von Polystyrol geforderten hohen Ansprüche, wie sehr gute Temperaturstabilität, in hohem Maß erfüllen.These dyes are known. According to the information in Swiss patent 374 964, one can they are used for dyeing polyolefin fibers from aqueous Use bath. It is therefore surprising when it has now been found that according to the invention too using dyes meet the high standards required for mass coloring of polystyrene, how much good temperature stability, meet to a high degree.

Die nach der Erfindung zu verwendenden 1,4-Dihydroxyanthrachinonderivate. die sich vorzüglich als orange bis rot färbende Farbstoffe für das Färben von Styrolpolymerisaten in der Masse eignen, sind in Nachbarstellung zu einer Hyrdrogruppe substituiert. Als Substituenten kommen in Betracht: Aminogruppen, Halogenatome, wie Chlor- oder Bromatome. Alkylreste, wie Methyl-, Propyl- oder Butylgruppen. Arylreste, wie Phcnylgruppen.

Aralkylaminoreste. wie die ResteThe 1,4-dihydroxyanthraquinone derivatives to be used according to the invention. which are excellent as orange to red coloring dyes for dyeing of styrene polymers are suitable in the mass, are substituted in the adjacent position to a hydrogroup. Possible substituents are: amino groups, halogen atoms, such as chlorine or bromine atoms. Alkyl radicals, such as methyl, propyl or butyl groups. Aryl radicals, such as phenyl groups. Aralkyl radicals, such as Benzyl or ethylbenzene groups, alkylaminoresy. such as methylaniino, ethylamino, propylamine. Stearylamino or cyelohexylnmino groups.

bis 200° C in einer Schneckenpresse mehrmals geknetet, bis eine homogene Färbung entstanden ist. Man läßt die aus Düsen austretende gefärbte Masse abkühlen und zerkleinert die Stränge in einer Abschlagmühle zu einem Granulat der Teilchengröße von etwa 2 bis 4 mm. Das so erhältliche Granulat wird in einer Spritzgußmaschine bei Temperaturen zwischen 200 und 220° C zu Formkörpern verarbeitet. Man erhält eine transparente orange Färbung von ausgezeichneter Lichtechtheit.Kneaded several times in a screw press up to 200 ° C until a homogeneous color is obtained. The colored mass emerging from the nozzles is allowed to cool and the strands are comminuted in a cut-off mill to a granulate with a particle size of about 2 to 4 mm. The granules obtainable in this way is processed into moldings in an injection molding machine at temperatures between 200 and 220 ° C. A transparent orange dyeing of excellent lightfastness is obtained.

Verfährt man wie angegeben, wobei man jedoch an Stelle von 2-Methylchinizarin solche Derivate des Chinizarins verwendet, die in 2-Stellung die nachfolgend genannten Substituenten enthalten, so erhält man Färbungen mit den in der Tabelle bezeichneten Farbtönen.If the procedure is as indicated, but instead of 2-methylquinizarin such derivatives of the Quinizarins used in the 2-position the following contain the substituents mentioned, then one obtains colorations with those indicated in the table Shades.
