Description

Druck- und Pflatschverfahren Es wurde gefunden, daß die nach dem Verfahren des Patents 483 154 darstellbaren alkalilöslichen Kondensationsprodukte, denen sehr wahrscheinlich die allgemeine Formel zukommt, sich hervorragend zur Erzeugung von Drucken auf pflanzlichen und tierischen sowie auf Kunstfasern eignen, Druckt oder pflatscht man diese Verbindungen in der üblichen Weise bei Gegenwart von Alkalien auf die Faser, so lassen sich die erhaltenen Drucke durch Behandeln mit Oxyd-ationsmitteln in die in dem Patent 483 154 beschriebenen blaugrünen Kondensationsprodukte vom Charakter von Küpenfarbstoffen überführen. Die Oxydation kann, durch Behandeln mit Ferricyankalium- oder Ammoniumpersulfa,flösung oder anderen Oxydationsmitteln, z. B. solchen, die bei schwach saurer Reaktion zur Anwendung gelangen, erfolgen. Beim Verhängen der Drucke an der Luft erfolgt die Oxydation etwas langsam#ei; in diesem Falle kann durch Anwendung geringer Mengen. von Katalysatoren, z. B. vanadinsaurer Salze u. dgl., die zweckmäßig der Druckpa#ste zugesetzt werden, die Oxydation beschleunigt werden.Printing and padding processes It has been found that the alkali-soluble condensation products which can be prepared by the process of patent 483,154, which very probably have the general formula are excellent for producing prints on vegetable, animal and synthetic fibers, if these compounds are printed or patted on the fiber in the usual manner in the presence of alkalis, the prints obtained can be converted into the in the blue-green condensation products described in the patent 483,154 of the character of vat dyes. The oxidation can, by treatment with ferricyanide or ammonium persulfa, solution or other oxidizing agents, e.g. B. those that are used in a weakly acidic reaction. When the prints are suspended in the air, the oxidation takes place somewhat slowly. in this case, small amounts can be used. of catalysts, e.g. B. vanadic acid salts and the like, which are expediently added to the printing paste, the oxidation are accelerated.

B e i s p i e 1 Man stellt eine Druckfarbe herdurch Verrühren von 5o - des im Beispiel des Patents 483 154 beschriebenen alkalilöslichen, bräunlichorange gefärbten Kondensationsproduktes, 50 9 Polyglycoläther, ioo g :2oprozentiger Sodalösung, 6oo g Stärke-Tragant-Verdickung und 2oo g Wasser bei gewöhnlicher Temperatur. Mit dieser Druckfarbe bedruckt oder bepflatscht man z. B. Kaliko und entwickelt den Farbstoff z. B. durch il/, Minuten langes Behandeln mit einer 2prozentigen Ferricyankalium- oder Ammoniumpersulfatlösung oder einer Lösung von i g Kaliumbichromat und 5 ccm 30prozentiger Essigsäure im Liter, oder man läßt die Drucke längere Zeit an der Luft verhängen. Hierauf spült man und seift kochend. Man erhält schöne blaugrüne Drucke von hervorragender Echtheit.B ice p y 1 Prepare a printing ink over the brook Zered stirring of 5o - the alkali-soluble described in the example of patent 483,154, brownish orange colored condensation product, 50 9 polyglycol ethers, ioo g: 2oprozentiger sodium carbonate solution, 6oo g starch tragacanth thickening and 2oo g of water at ordinary temperature. With this printing ink printed or padded z. B. calico and develops the dye z. B. by treatment with a 2 percent potassium ferricyanide or ammonium persulfate solution or a solution of 1 g of potassium dichromate and 5 cc of 30 percent acetic acid per liter for a long time, or the prints are left in the air for a longer period of time. Then you wash up and soap at the boil. Beautiful blue-green prints of excellent fastness are obtained.
