Description

Verfahren zur Herstellung wertvoller Färbungen und Drucke auf Celluloseestern oder -äthern Es wurde gefunden, daß die Kondensationsprodukte aus aliphatischen Aminen und Naphthazarin wertvolle Färbungen und Drucke auf Celluloseestern öder -äthern liefern. Man erhält mit ihnen beim Färben nach den für Celluloseester oder -:äther üblichen Arbeitsweisen kräftige Färbungen verschiedener Nuancen von wertvollen Echtheitseigenschaften.Process for the production of valuable dyeings and prints on cellulose esters or ethers It has been found that the condensation products of aliphatic Amines and naphthazarin valuable dyeings and prints on cellulose esters are wasted - deliver ethers. One obtains with them when dyeing according to the for cellulose esters or -: ethereal working methods strong colorations of various nuances of valuable ones Authenticity properties.

Beispiel i Man färbt ioo Gewichtsteile Acetatseide in einem Bade, welches in 2ooo Volumteilen 3 Gewichtsteile des durch Erhitzen von Naphthazarin mit einer wässerigen Methylaminlösung unter Zusatz von wenig Zinkstaub auf 6o" erhältlichen und durch. Kristallisieren aus -Monochlorbenzol gereinigten Trimonomethylaminon;aphthochinons und zweckmäßig etwa 5 Gewichtsteile Seife enthält, bei ¢o bis 70° während i"2 bis i Stunde. Beispiel 2 Mit einer Kombination, die aus 3 % Trimonomethylaminonaphtho,chänon, o,8 % einer nach Patent 4.17 q.2o, K1. 22a, aus p-Nitranilin und Oxyäthyl-m-toluidin hergestellten Azoverbindung und 0,3 % i-Amino-q.--oxy-anthrachinon besteht, erzielt man in direkter Ausfärbung auf Cellulosee.stern oder ,äthern ein blumiges, echtes Schwarz.Example i 100 parts by weight of acetate silk are dyed in a bath which in 2,000 parts by volume 3 parts by weight of the by heating naphthazarine with an aqueous methylamine solution with the addition of a little zinc dust to 6o "available and through. Crystallize from -Monochlorobenzene Purified Trimonomethylaminon; Aphthochinons and expediently contains about 5 parts by weight of soap, at ¢ 0 to 70 ° while i "2 to i hour. Example 2 With a combination consisting of 3% trimonomethylaminonaphtho, chänon, 0.8% one according to patent 4.17 q.2o, K1. 22a, from p-nitroaniline and oxyethyl-m-toluidine produced azo compound and 0.3% i-amino-q .-- oxy-anthraquinone is achieved one in direct coloring on Cellulosee.stern or, ether a flowery, real one Black.
