Description

Es wurde gefunden, daß die Tetraaminoanthrachinone, in welchen eine oder zwei Aminogruppen aryliert sind und die weder Sulfo- noch Carboxylgruppen enthalten, sich zur Herstellung echter Töne auf den Estern und Äthern der Cellulose sehr gut eignen, indem sie dieses Material aus wäßrigen Suspensionen bzw. Emulsionen in blauen bis grünen Tönen färben, welche sich gegenüber den nicht arylierten Produkten durch wesentlich verbesserte Echtheitseigenschaften auszeichnen. It has been found that the tetraaminoanthraquinones in which one or two Amino groups are arylated and which contain neither sulfo nor carboxyl groups very well suited for the production of real tones on the esters and ethers of cellulose, by converting this material from aqueous suspensions or emulsions in blue to green tones, which differ significantly from the non-arylated products characterized by improved fastness properties.

Beispielexample

0,5 Teile 1, 5-Diamino-4, 8-diphenylaminoanthrachinon, welche in feine Verteilung gebracht worden sind, z. B. durch Lösen in Schwefelsäure, Austragen in Wasser, Filtrieren und Verreiben des Rückstandes mit Sulfitcelluloseablauge oder Türkischrotöl oder den Kondensationsprodukten aus Formaldehyd und Napthalinsulfonsäuren oder noch den Produkten des schweizerischen Patents 122569 und des deutschen Patents 506838, werden in etwa 3000 Teile Wasser eingetragen. Hierauf geht man mit 100 Teilen Acetatseidegarn bei 300 ein, treibt die Temperatur bis 70 bis 75° und färbt eine Stunde bei dieser Temperatur. Dann wird in üblicher Weise gespült, aviviert und getrocknet. Die Acetatseide wird in grünblauen Farbtönen von vorzüglichen Echtheitseigenschaften gefärbt. Wesentlich rötere bzw. blauere Farbtöne werden mit dem 1, 8-Dianilido-4, 5-diaminoanthrachinon erhalten, während das i, 5~Diamino-4, 8-(4', 4"-diamino)-dianilidoanthrachinon blaugrüne Nuancen gibt. Mit dem i-Anilido-4, 5, 8-triaminoanthrachinon werden blaue Färbungen erhalten.0.5 parts of 1, 5-diamino-4, 8-diphenylaminoanthraquinone, which have been finely divided, e.g. B. by dissolving in sulfuric acid, discharging into water, filtering and triturating the residue with sulfite cellulose waste liquor or Turkish red oil or the condensation products of formaldehyde and naphthalenesulfonic acids or the products of Swiss patent 122569 and German patent 506838, about 3000 parts of water are entered. Thereon is entered at 30 0 with 100 parts Acetatseidegarn, the temperature drives up to 70 to 75 °, and dyeing for one hour at this temperature. It is then rinsed, finished and dried in the usual way. The acetate silk is dyed in green-blue shades with excellent fastness properties. Significantly redder or bluer shades are obtained with the 1,8-dianilido-4,5-diaminoanthraquinone, while the 1,5-diamino-4, 8- (4 ', 4 "-diamino) -dianilidoanthraquinone gives blue-green shades the i-anilido-4, 5, 8-triaminoanthraquinone, blue colorations are obtained.

Claims (1)

Patentanspruch :Claim: Verfahren zum Färben von Celluloseestern und -äthern mit Tetraaminoanthrachinonen, dadurch gekennzeichnet, daß dieses Material mit solchen Tetraaminoanthrachinonen gefärbt wird, in welchen eine oder zw'ei der Aminogruppen durch einen Arylrest substituiert sind und die weder Sulfo- noch Carboxylgruppen enthalten. Process for coloring cellulose esters and ethers with tetraaminoanthraquinones, characterized in that this material with such tetraaminoanthraquinones is colored, in which one or two of the amino groups are substituted by an aryl radical and the contain neither sulfo nor carboxyl groups.
