Abstract

Novel azo pigments of formula (I) (in which R is methyl or ethyl), are useful in colouring auto and industrial lacquers, plastics, printing inks. spinning compsns, etc. in orange shades. (I) gives brilliant full shades with very good light- and weather-fastness and high covering power. (I) are obtd. by diasotisation of cpd. (II) followed by coupling with (III).

Description

Pizmentfarbstoffe Die Erfindung betrifft die Farbstoffe der Formel in der R Athyl oder vorzugsweise Methyl ist.Pizza dyes The invention relates to the dyes of the formula in which R is ethyl or preferably methyl.

Die Farbstoffe haben ausgezeichnete Pigmenteigenschaften.The dyes have excellent pigment properties.

Insbesondere zeigen sie bei brillantem Voll ton sehr gute Licht- und Wetterechtheit und sehr hohes Deckvermögen, so daß sie besonders zur Färbung von Auto- und Industrielacken geeignet sind. Die Farbstoffe können aufgrund ihrer guten Echtheiten auch zum Färben von Kunststoffen, wie Gummi, PVC, Polystyrol, zur Herstellung von Druckfarben, zum Spinnfårben oder zu anderen bekannten Pigmentverwendungszwecken benutzt werden.In particular, they show very good light and color with a brilliant full tone Weather fastness and very high hiding power, making them particularly suitable for coloring Car and industrial paints are suitable. The dyes can be due to their good Fastness properties also for coloring plastics such as rubber, PVC, polystyrene, for manufacturing from printing inks, spin dyeing, or other known pigment uses to be used.

Die Herstellung der Farbstoffe erfolgt auf an sich bekannte Weise durch Diazotieren von 2-Methyl- oder 2-Athylsulfonyl-4-nitranilin und Kuppeln auf 2,4-Diamino-6-hydroxypyrimidin.The dyes are produced in a manner known per se by diazotizing 2-methyl- or 2-ethylsulfonyl-4-nitroaniline and domes 2,4-diamino-6-hydroxypyrimidine.

Nach der Abtrennung können die Farbstoffe gegebenenfalls in an sich bekannter Weise in eine physikalische Form Uberftihrt werden, die der gewünschten speziellen Verwendung am besten angepaßt ist.After the separation, the dyes can, if appropriate, per se can be converted into a physical form which is the desired one in a known manner is best adapted to specific use.

Beispiel 21,6 g p-Nitranilin-o-methylsulfon werden bei.O bis 500 in 46 g 98 kige Schwefelsäure eingetragen, dann werden 29 g 45 ziege Nitrosylschwefelsäure zugetropSt, und es wird 6 Stunden gerührt. Die Lösung wird dann unter kräftigem Rühren auf 150 g Eis getropft. Die so erhaltene Diazolösung wird zu einer Suspension von 21,8 g 2,4-Diamino-6-hydroxypyrimidinsulfat, 9 g Natriumhydroxid und 10 g Natriumacetat in 350 ml Wasser zugetropft und kräftig gerührt. Example 21.6 g of p-nitroaniline-o-methylsulfone are added at. 0 to 500 entered in 46 g of 98 kige sulfuric acid, then 29 g 45 goat Nitrosylsulfuric acid is added dropwise, and the mixture is stirred for 6 hours. The solution will be then added dropwise to 150 g of ice with vigorous stirring. The diazo solution thus obtained becomes a suspension of 21.8 g of 2,4-diamino-6-hydroxypyrimidine sulfate, 9 g of sodium hydroxide and 10 g of sodium acetate in 350 ml of water were added dropwise and stirred vigorously.

Nach dreistündigem Rühren wird abgesaugt und mit Wasser gewaschen. Das Filtergut wird in 200> ml Wasser suspendiert und 3 Stunden bei 950C gerührt, danach abgesaugt, gewaschen und getrocknet. Man erhält so 31 g eines orange gefärbten Pigments, das beim Einfärben in Lack eine brillante, sehr stark deckende, licht-, wetter- und überspritzechte Orangefärbung ergibt,After three hours of stirring, it is filtered off with suction and washed with water. The filter material is suspended in 200 ml of water and stirred for 3 hours at 950C, then suctioned off, washed and dried. This gives 31 g of an orange colored one Pigments, which, when colored in lacquer, produce a brilliant, very opaque, light, weather and oversprayed orange color results,
