Abstract

Thermoplastics are coloured with dyes of formula (I): where A' is a gp. A or a gp. (II) D is the residue of a diazo component, R is H, alkyl or (methyl)phenyl, X is H, carbamoyl or CN, Z is a (cyclo) alkylene, aralkylene or arylene gp., where the alkylene gp. may be interrupted by O, S or N-substd. imino, and A is H, (substd.) (cyclo)alkyl, aralkyl, phenyl or acyl or may together form a 5-7 membered heterocyclic ring with N. (I) are used for dyeing thermoplastics in bulk at is not >300 degrees C, e.g polystyrene, hard PVC, polyethylene, polyamides, polyesters, polycarbonates, styrene-butadiene copolymers and ABS copolymers. (I) are stable to heat. They have up to 3.5 x the colour strength of dyes normally used for dyeing in bulk.

Überraschenderweise eignen sich die Farbstoffe der Formel I zum Färben zu von Thermoplasten in der Masse, bei Temperaturen von bis ungefähr 300 00. Dieses Verhalten war bei den Azofarbstoffen der Formel I nicht vorhersehbar, da Dispersions-Azofarbstoffe normalerweise nicht so temperaturstabil sind. Insbesondere überrascht es, daß die Azo-Farbstoffe beim Einschmelzen in Polyamid hoch temperaturstabil sind. Färbbare Thermoplasten sind beispielsweise Polystyrol, Hart-Polyvinylchlorid, Polyäthylen, Polyamid, Polyester, Polypropylen, sowie Styrol-Butadien Gemische oder Acrylnitril-Butadien-Styrol Gemische. Man erhält Färbungen mit vorzüglichen Echtheiten, insbesondere Licht-, Wetter- und Weichmacherechtheiten. Die Weichmacherechtheiten lassen sich zudem durch die Wahl der Reste A steuern, die Lichtechtheit hängt im wesentlichen von D und X ab.Surprisingly, the dyes of the formula I are suitable for dyeing to of thermoplastics in bulk, at temperatures of up to about 300 00. This The behavior of the azo dyes of the formula I could not be foreseen, as dispersion azo dyes are usually not as temperature stable. In particular, it is surprising that the Azo dyes are highly temperature stable when melted in polyamide. Dyeable Thermoplastics are, for example, polystyrene, hard polyvinyl chloride, polyethylene, Polyamide, polyester, polypropylene, as well as styrene-butadiene mixtures or acrylonitrile-butadiene-styrene Mixtures. The dyeings obtained have excellent fastness properties, in particular light, Weather and plasticizer fastnesses. The plasticizer fastnesses can also be passed through control the choice of the radicals A, the light fastness depends essentially on D and X off.

In den folgenden Beispielen beziehen sich Angaben über Teile und Prozente, sofern nicht anders vermerkt, auf das Gewicht.In the following examples, parts and percentages relate to unless otherwise noted, by weight.

Beispiel 1 29,5 Teile 2-Aminobenzonitril werden bei Raumtemperatur in 800 Raumteilen Wasser und 80 Raumteilen 30 zeiger Salzsäure gelöst. Dann setzt man 750 Teile Eis und bei 0 bis 5 0 77 Baumteile einer 23 zeigen Natriumnitritlösung auf einmal zu. Nach zwei Stunden Rühren bei 0 bis 5 0 wird die klare bis trübe Diazoniumsalzlösung mit folgender Suspenion versetzt: 66,0 Teile 2,6-Bis-(ß-methoxyäthylamino)-5-cyan-4-methylpyridin werden in 80 Raumteilen Dimethylformamid unter Erwärmen gelöst, dann setzt man 12,5 Teile eines Anlagerungsproduktes von etwa 23 Mol Äthylenoxyd an 1 Mol Spermölalkohol zu und gibt die Lösung unter Rühren zu einem Gemisch aus 30 Raumteilen 30 %iger Salzsäure und 10Q0 Raumteilen Wasser.Example 1 29.5 parts of 2-aminobenzonitrile are at room temperature dissolved in 800 parts by volume of water and 80 parts by volume of 30 pointers hydrochloric acid. Then sets 750 parts of ice and 0 to 5 0 77 tree parts of a 23 show sodium nitrite solution at once to. After two hours of stirring at 0 to 50, the clear to cloudy diazonium salt solution becomes mixed with the following suspension: 66.0 parts of 2,6-bis (ß-methoxyethylamino) -5-cyano-4-methylpyridine are dissolved in 80 parts by volume of dimethylformamide with heating, then 12.5 are added Parts of an adduct of about 23 moles of ethylene oxide with 1 mole of sperm oil alcohol and adds the solution with stirring to a mixture of 30 parts by volume of 30% strength Hydrochloric acid and 10Q0 parts by volume of water.

lö sung Die Kupplungswird mit etwa 500 bis 1000 Teilen Eis und dann mit etwa 65 Teilen 50 %iger Natronlauge versetzt, bis der pE-wert des Gemisches 2,5 bis 3,2 ist. Nach beendeter Kupplung wird das Gemisch auf 70 OC erwärmt, abfiltriert und mit heißem Wasser gewaschen. Nach dem Trocknen erhält man etwa 97 bis 98 Teile eines gelben Pulvers der Formel das sich in Dimethylformamid mit gelber Farbe löst.solution The coupling is mixed with about 500 to 1000 parts of ice and then with about 65 parts of 50% sodium hydroxide solution until the pE value of the mixture is 2.5 to 3.2. After the coupling has ended, the mixture is heated to 70 ° C., filtered off and washed with hot water. After drying, about 97 to 98 parts of a yellow powder of the formula are obtained which dissolves in dimethylformamide with a yellow color.

0,5 Teile dieses Farbstoffes werden mit 1000 Teilen Polystyrolgranulat oder -Pulver nach bekanntem Verfahren intensiv vermischt. Anschließend wird das Gemisch geschmolzen. Der Farbstoff löst sich dabei und ist in der Schmelze bis 300 0 stabil. Nach dem Erstarren erhält man eine kräftig gelb gefärbte Polystyrolmasse mit vorzüglicher Lichtechtheit.0.5 parts of this dye are mixed with 1000 parts of polystyrene granules or powder mixed intensively according to a known method. Then the Melted mixture. The dye dissolves in the process and is up to 300 in the melt 0 stable. After solidification, a bright yellow colored polystyrene mass is obtained with excellent lightfastness.

Der Farbstoff läßt sich ebenso temperaturstabil in Polyamid einschmelzen.The dye can also be melted into polyamide in a temperature-stable manner.

Auch diese Massefärbung ist sehr gut lichtecht. Weiterhin ist er sehr gut zur Massefärbung von Polypropylen, Polyäthylen, Polyvinylchlorid und Polyester geeignet.This mass coloring is also very lightfast. Furthermore, he is very good for mass coloring polypropylene, polyethylene, polyvinyl chloride and polyester suitable.

Beispiel 2 78 Teile 1-Amino-2-trifluormethyl-4-chlor-benzol werden bei 0 bis 20 °C in 400 Teilen96 der Schwefelsäure ist. Man kühlt das Gemisch auf 0 - 4 °C ab, setzt 130 Teile 45 %ige Nitrosylschwefelsäure zu und rührt 3 Stunden bei 0 bis 5 00. Dann wird das Gemisch unter Rührern auf 1200 Teile Eis gegeben, 30 Minuten nachgerührt und filtriert. Nach Zerstörung von überschüssiger salpetriger Säure wird die Diazoniumsalzlösung mit 117 Teilen der Kupplungskomponente der Formel versetzt und der pH-Wert der Kupplungslösung durch Zusatz von Natronlauge bei 0 bis 50C auf 2 bis 3 angehoben. Nach beendeter Kupplung saugt man den ausgefallenen Farbstoff der Formel ab, wäscht ihn mit Wasser und trocknet.Example 2 78 parts of 1-amino-2-trifluoromethyl-4-chlorobenzene are dissolved in 400 parts of sulfuric acid at 0 to 20 ° C. The mixture is cooled to 0-4 ° C., 130 parts of 45% strength nitrosylsulfuric acid are added and the mixture is stirred for 3 hours at 0-5,000. The mixture is then poured onto 1200 parts of ice with stirring, stirred for 30 minutes and filtered. After excess nitrous acid has been destroyed, the diazonium salt solution with 117 parts of the coupling component of the formula added and the pH of the coupling solution was raised to 2 to 3 by adding sodium hydroxide solution at 0 ° to 50 ° C. After the coupling has ended, the dyestuff of the formula which has precipitated out is sucked off wash it off with water and dry it.

Färbt man 1 000 Teile Polystyrol mit 0,5 Teilen dieses Farbstoffs analog Beispiel 1, so erhält man eine gelb gefärbte Polystyrolmasse mit sehr guter Lichtechtheit.1,000 parts of polystyrene are dyed with 0.5 part of this dye analogously to Example 1, a yellow-colored polystyrene composition with a very good color is obtained Lightfastness.
