Description
Verfahren zur Herstellung echter Drucke. Es wurde gefunden, daß man echte Drucke herstellen kann, wenn man Gemische von Alkalisalzen der Azokomponenten, welche zur Herstellung von Azofarbstoffen auf der Faser geeignet sind, und der Sulfnitrosaminsätiren von Aminoazokörpern der allgemeinen Formel worin R und R' aromatische Reste bedeuten, m it den in der Drucktechnik üblichen Zusati zen auf dieFaser aufbringt, dämpft und durch Säuren oder Lösungen von sauren Salzen und sodann durch Alkalilösungen passiert. Es entstehen auf diese Weise völlig waschechte-Drucke. Bei der bekannten Zersetzlichkeit der stilfnitrosaminsauren Salze, besonders in trockenem Zustande (vgl. Berichte 28, 3 164, sowie Berichte 30, 870, 87d., 88o), erscheint es durchaus überraschend, daß diese in den Gemischen finit den Alkalisalzen der Azokomponenten den Trocken- und Dämpfprozeß aushalten, und daß man brauchbare, volle Färbungen erhält.Process for making real prints. It has been found that true prints can be produced by using mixtures of alkali salts of the azo components, which are suitable for the production of azo dyes on the fiber, and the sulfnitrosamine saturations of amino azo bodies of the general formula where R and R 'denote aromatic radicals, with the additives customary in printing technology, applies, steams and passes through acids or solutions of acidic salts and then through alkali solutions. In this way, completely real prints are created. Given the known decomposability of the stilfnitrosamic acid salts, especially in the dry state (see Reports 28, 3 164, as well as Reports 30, 870, 87d., 88o), it appears quite surprising that these in the mixtures are finite to the alkali salts of the azo components in the dry - withstand the steaming process, and that you get usable, full colorations.
Weiterhin wurde beobachtet, daß man bei dem Verfahren nicht von den Sulfnitrösaniina.lkalisalzen auszugehen braucht, sondern daß man dieselben guten Resultate erhält, wenn inan Gemische von Alkalisalzen der Azokomponenten, der Stilfaminoazoverbindungen und Alkalinitrit verwendet. Vielleicht entstehen interniediä r die Stilfnitrosaminsäuren, welche dann, wie oben dargelegt, mit den betreffenden Azokomponenten Farbstoffe bilden. Daß eine derartige Arbeitsweise möglich ist, war in keiner Weise vorauszusehen, da bei der Anwesenheit von zwei zur Bildung von Nitrosoderivaten befähigten Körpern, Sulfaminsäure und Azokomponente, die Möglichkeit vorlag, daß die frei werdende salpetrige Säure ganz oder zum großen Teil zur Nitrosierung der Azokomponente verbraucht werden würde, so daß entweder gar keine oder nur schwache Färbungen entständen. Man ei-hält aber auch auf diese Weise schöne, satte Drucke.It was also observed that the process does not involve the Sulphnitrösaniina.lkalisalzen needs to go out, but that one needs the same good ones Results are obtained when using mixtures of alkali salts of the azo components, the stilfaminoazo compounds and alkali nitrite are used. Maybe the stilfnitrosamic acids arise internally, which then, as set out above, with the relevant azo components dyes form. That such a way of working would be possible was by no means foreseeable, because in the presence of two bodies capable of forming nitroso derivatives, Sulfamic acid and azo component, the possibility existed that the nitrous acid that was released Acid can be completely or largely consumed for nitrosation of the azo component so that either no coloration at all or only weak coloration would result. One holds but also beautiful, rich prints in this way.
Die neuen Druckfarben können auch im Nfehrfarbendruck neben den bekannten
Nitresamindruckfarben verwendet werden.
Beispiel 3.
Man erhält einen Zweifarbendruck, ein blumiges Schwarz neben Rot.A two-color print is obtained, a flowery black next to red.
Mit anderen 2 - 3-Oxynaphthoesäurearylamiden sowie mit anderen Azokomponenten, wie z. B. ß-Naphthol, die Acylaminonaphthole, die in der amerikanischen Patentschrift 145366o erwähnten Derivate der i-Oxynaphthalin-4-carbonsäure, ferner Körper, welche eine kupplungsfähige, saure Methylengruppe enthalten, also beispielsweise Pyrazolonderivate oder Abkömmlinge des ß-Ketonaldehyds, z. B. Acylessigsäurearylide, wie sie in der französischen Patentschrift 5672,84 beschrieben sind, und anderen Sulfaminoazokörpern bzw. deren Nitrosoverbindungen kann das Verfahren in der gleichen Weise durchgeführt werden.With other 2 - 3-Oxynaphthoesäurearylamiden and with other azo components such. B. ß-naphthol, the acylaminonaphthols, the derivatives of i-oxynaphthalene-4-carboxylic acid mentioned in American patent specification 145366o, and also bodies which contain an acidic methylene group capable of coupling, for example pyrazolone derivatives or derivatives of ß-ketone aldehyde, e.g. B. acyl acetic arylides, as described in French patent 5672.84, and other sulfaminoazo bodies or their nitroso compounds, the process can be carried out in the same way.
