Zusatz zum Patente 206320 vom 9. Mai 1907.Addendum to patent 206320 of May 9, 1907.
In der Patentschrift 206320 ist in bezug auf ein Verfahren zur Herstellung lichtempfindlicher Molybdänschichten gezeigt worden, daß Molybdänsäurederivate, dem bekannten Sensibilisierungsgemisch für Eisenblaupapiere zugesetzt, die Empfindlichkeit dieser Papiere bedeutend steigern.The patent specification 206320 relates to a method for producing more photosensitive Molybdenum layers have been shown to be molybdic acid derivatives, the well-known sensitizing mixture added for iron blue papers, significantly increase the sensitivity of these papers.
Im weiteren Verlaufe von in dieser Richtung angestellten Versuchen ergab sich, daß nicht nur die erwähnten Abkömmlinge der Molybdänsäure imstande sind, eine derartig günstige Wirkung auf Eisenblaupapiere auszuüben, sondern daß diese Eigenschaft auch den Verbindungen solcher Metalle zukommt, die gleich dem Molybdän in ihren höheren Oxydationsstufen Lichtempfindlichkeit zeigen. Solche Verbindungen sind die Salze des Uranyls, des Kobalt- und des Manganoxyds.In the further course of experiments made in this direction, it turned out that this was not the case only the above-mentioned derivatives of molybdic acid are capable of producing such a favorable one Effect on iron blue papers, but that this property also affects the compounds such metals belong to, which are like molybdenum in their higher degrees of oxidation Show sensitivity to light. Such compounds are the salts of uranyl, des Cobalt and manganese oxide.
Bereitet man z. B. eine Normalmischung von rotem Blutlaugensalz; und Ferriammoniumcitrat und setzt diesem Gemisch kleinere Mengen von Uranylnitrat und Ammoniumoxalat, Cobaltioxalat oder Manganisalz, das nach Lumiere (Eder, Jahrbuch der Photographic 1893, S. 48) bereitet wurde, hinzu, so sind die mit Zusätzen genannter Oxydsalze sensibilisierten Papiere erheblich empfindlicher als das mit der Normallösung präparierte.If you prepare z. B. a normal mixture of red blood liquor salt; and ferric ammonium citrate and adds smaller amounts of uranyl nitrate and ammonium oxalate, cobalt dioxalate or manganese salt to this mixture Lumiere (Eder, Jahrbuch der Photographic 1893, p. 48) was added, so are the papers sensitized with the addition of the named oxide salts are considerably more sensitive than that prepared with the normal solution.
Diese Erfahrungen, die experimentell in den Versuchen mit Molybdänsäurederivaten, mit Salzen des Uranyls, des Kobalt- und Manganoxyds begründet sind, scheinen allgemeine Bedeutung zu haben.These experiences, which were made experimentally in the experiments with molybdic acid derivatives, with Salts of uranyl, cobalt and manganese oxide seem to be of general importance to have.
Die Lösungen, welche zum Sensibilisieren von Eisenblaupapieren benutzt werden, bestehen im wesentlichen aus einem Gemisch von Ferrisalzen mit Kaliumferricyanid. Bei der Belichtung bildet sich durch Reduktion der Ferrisalze Ferrosalz, das beim Entwickeln unter Bildung von Turnbullblau mit dem Ferricyanid reagiert und die blaue Bildsubstanz liefert. Sind aber, wie in dem vorliegenden Fall, dem Sensibilisierungsgemisch weitere lichtempfindliche Stoffe einverleibt, so wird sich außer der erwähnten Hauptreaktion eine Nebenreaktion abspielen, die eben die Erhöhung der Empfindlichkeit zur Folge hat. Denn außer der bekannten Zersetzung des Eisenoxyd-Ferricyankaliumgemisches findet bei der Belichtung solcher Papiere eine Reduktion der höheren Oxydationsstufen zu niederen statt. Diese letzteren wirken auf das überschüssige Ferriferricyankalium reduzierend ein, so daß bei der Entwicklung der Papiere im Wasser sich nicht nur die der Hauptreaktion, sondern die der letzterwähnten Nebenreaktion entsprechende Menge blauer Bildsubstanz bildet.The solutions used to sensitize iron blue papers are in essentially from a mixture of ferric salts with potassium ferricyanide. In the exposure Ferrous salt is formed by reduction of the ferric salts, which is formed during development von Turnbullblau reacts with the ferricyanide and supplies the blue image substance. Are but, As in the present case, add other light-sensitive substances to the sensitization mixture incorporated, in addition to the main reaction mentioned, a side reaction will take place, which just results in an increase in sensitivity. Because apart from the known Decomposition of the mixture of iron oxide and ferricyanide takes place on exposure to light Paper a reduction of the higher oxidation levels to lower ones instead. These latter have a reducing effect on the excess potassium ferricyanide, so that during development of the papers in the water not only corresponds to that of the main reaction, but also that of the last-mentioned side reaction Amount of blue image substance forms.
Ferner ist als allgemein gültige ErklärungIt is also a generally applicable declaration
für diese Erscheinung in Betracht zu ziehen, daß die Reduktionsprodukte der Molybdänsäurederivate, der Uranyl-, Kobalti- und Manganisalze als Übertrager wirken können, indem sie durch das vorhandene Ferriferricyankaliumgemisch unter gleichzeitiger Bildung von Berliner- und Turnbullblau zurückoxydiert werden und so die Lichtwirkung von neuem wesentlich unterstützen können.for this phenomenon to consider that the reduction products of the molybdic acid derivatives, the uranyl, cobaltic and manganese salts can act as transmitters by it by the existing ferriferricyan potassium mixture with simultaneous formation of Berliner- and Turnbull blue are re-oxidized and so the lighting effect is again essential can support.

Präpariert man Papier oder irgendeinen anderen Schichtträger mit diesen Lösungen, so zeichnen sich diese Präparate durch ihre erhöhte Lichtempfindlichkeit gegenüber solchen aus, die nur mit dem entsprechenden Ferriferricyangemisch allein sensibilisiert wurden.If you prepare paper or any other support with these solutions, these preparations are characterized by their increased sensitivity to light which were only sensitized with the corresponding ferriferricyan mixture alone.
