Tn beiden Fällen wird nach dem Drucken und Trocknen die Farbe entweder durch längeres Verhängen in der Wärme oder besser noch durch 5 Minuten langes Dämpfen im Matherplatt entwickelt, dann gewaschen und geseift. Durch Passage in einer Bichromatlösung erfährt die braune Farbe noch eine Vertiefung.In both cases, after printing and drying, the color either takes longer Hang up in the warmth or better still by steaming for 5 minutes in the Matherplatt developed, then washed and soaped. Learned by passage in a bichromate solution the brown color is still a depression.

KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. PATENTSCHRIFTPATENT LETTERING KLASSE Sn. GRUPPECLASS Sn. GROUP Patentiert im Deutschen Reiche vom 24. Januar 1913 ab.Patented in the German Empire on January 24, 1913. Es wurde gefunden, daß man braune bis graue Drucke von guten Echtheitseigenschaften erhält, wenn man ätzalkalische Lösungen von Aminonaphtolen, vorteilhaft unter Zusatz von Formaldehyd oder von Aceton oder Alkohol, zweckentsprechend verdickt, auf die pflanzliche Faser aufbringt und nach dem Trocknen entweder durch längeres Verhängen oder durch Dämpfen entwickelt. FormaldehydIt has been found that brown to gray prints with good fastness properties can be obtained obtained when caustic solutions of aminonaphthols, advantageously with addition of formaldehyde or of acetone or alcohol, appropriately thickened, to the vegetable fiber and, after drying, either by prolonged hanging or developed by steaming. formaldehyde ίο beschleunigt die Entwicklung der Farbe und verkürzt demnach die Dauer des Dämpfens oder Verhängens, während ein Zusatz von Alkohol oder Aceton die Druckfarbe langer flüssig und brauchbar erhält. Durch eine nachträgliche Chromatpassage der fertigen Drucke kann die Nuance vertieft werden.ίο accelerates the development of color and accordingly shortens the duration of steaming or impregnation, while the addition of alcohol or acetone keeps the printing ink liquid and usable for longer. By a Subsequent chromate passage of the finished prints can deepen the nuance. Von den bekannten Aminonaphtolen wurden die folgenden als besonders brauchbar befunden: Of the known aminonaphthols, the following have been found to be particularly useful: 2 · 5-Aminonaphtol, 2 · 8-Aminonaphtol, 1 · 5-Aminonaphtol, 1 · 7-Aminonaphtol oder Gemenge dieser Körper.2 · 5-aminonaphtol, 2 · 8-aminonaphtol, 1 · 5-aminonaphtol, 1 · 7-aminonaphtol or mixture of these bodies.
