Description
Die Erfindung betrifft eine photographische Silber-' halogenidemulsion mit einem sauerstoff-, schwefel- oder -selenhaltigen quaternären Cycloammoniumsalz als Antischleiermittel.The invention relates to a photographic silver 'halide emulsion with an oxygen, sulfur or selenium-containing quaternary cycloammonium salt as an antifoggant.
Es ist bekannt, daß photoempfindliche Emulsionen zur Schleierbildung neigen, d. h. bei längerer Lagerung auch ohne Belichtung entwickelbar werden. Um diesem Nachteil abzuhelfen, sind verschiedene Substanzen bereits als Antischleiermittel angewandt worden, die jedoch wieder andere Nachteile besitzen, nämlich die Verringerung der Empfindlichkeit und/oder des Kontrastes der Emulsion. Dies gilt insbesondere bei spektral sensibilisierten Schichten, wie sie in der Farbphotographie angewandt werden. Diese Verschlechterung der Emulsionen ist bei Anwendung mehrerer Antischleiermittel in Verbindung mit sonstigen Zusätzen oft beträchtlich. So ist aus der USA.-Patentschrift 2131038, die als Antischleiermittel quaternäre Cycloammoniumsalze, nämlich N-alkylsubstituierte Azole erwähnt, zu entnehmen, daß diese Schichten eine bemerkenswerte Desensibilisierung zeigen.It is known that photosensitive emulsions have a tendency to fog; H. for longer Storage can also be developed without exposure. To remedy this disadvantage, there are several Substances have already been used as antifoggants, but have other disadvantages namely, reducing the sensitivity and / or contrast of the emulsion. This applies in particular to spectrally sensitized layers such as those used in color photography will. This deterioration of the emulsions is with the use of multiple antifoggants often considerable in connection with other additives. So is from the USA patent specification 2131038, the quaternary antifoggant Cycloammonium salts, namely N-alkyl-substituted azoles mentioned, can be seen that these layers show remarkable desensitization.
Es wurden aber auch schon an Stickstoff sulfoalkylierte Thioazolverbindungen selbst als Zusatz zu einer Silberhalogenidemulsion vorgeschlagen. Die zuzusetzende Menge belief sich jedoch hierbei auf mindestens 1 Mol dieser Verbindungen pro Mol Silberhalogenid und bezweckte, das Nachdunkeln des entwickelten Bildes bei gewöhnlicher Raumbeleuchtung zu verhindern und das übliche Fixieren, z. B. mit Natriumthiosulfat, überflüssig zu machen.But there have already been sulfoalkylated on nitrogen Thioazole compounds themselves have been suggested as an additive to a silver halide emulsion. the However, the amount to be added was at least 1 mole of these compounds per mole Silver halide and aimed to darken the developed image in normal room lighting to prevent and the usual fixing, z. B. with sodium thiosulfate, to make superfluous.
Aufgabe der Erfindung ist es, eine photographische Silberhalogenidemulsion anzugeben, die als Antischleiermittel ein quaternäres Cycloammoniumsalz enthält, das neben einer vorteilhaften Wirksamkeit als Antischleiermittel nicht zu einer Verschlechterung der Empfindlichkeit und des Kontrastes führt. Dies gilt auch für solche Wellenlängen, für die eine Emulsion erst auf Grund einer spektralen Sensibilisierung empfindlich ist.The object of the invention is to provide a silver halide photographic emulsion useful as an antifoggant contains a quaternary cycloammonium salt which, in addition to having a beneficial effect as an anti-fogging agent does not lead to deterioration in sensitivity and contrast. this also applies to those wavelengths for which an emulsion is only due to a spectral sensitization is sensitive.
Der Gegenstand der Erfindung geht daher aus von einer photographischen Silberhalogenidemulsion mit einem sauerstoff-, schwefel- oder selenhaltigen quaternären Cycloammoniumsalz als Antischleiermittel und ist dadurch gekennzeichnet, daß sie in einer Konzentration von 0,005 bis 5 g pro Mol Silberhalogenid ein quaternäres Cycloammoniumsalz der allgemeinen FormelThe object of the invention is therefore based on a photographic silver halide emulsion a quaternary cycloammonium salt containing oxygen, sulfur or selenium as an antifoggant and is characterized in that it is used in a concentration of 0.005 to 5 grams per mole of silver halide a quaternary cycloammonium salt of the general formula

It is also possible to use it as a to apply coating immediately before the application of the emulsion on a film carrier, with also under These conditions allow the anti-fogging agent to penetrate into the already applied and dried one Emulsion takes place.
Die jeweils anzuwendende Menge an erfindungsgemäßem Antischleiermittel richtet sich nach den Eigenschaften der Emulsion selbst, nämlich ihrer spezifischen Neigung zur Schleierbildung. Größere Mengen an Antischleiermittel als die obengenannten bringen keine weiteren Vorteile mehr; geringere Mengen führen zu einer ungenügenden Stabilisierung. Es wird noch darauf hingewiesen, daß selbst bei beträchtlichen Mengen es zu keiner Desensibilisierung kommt.The amount of antifoggant according to the invention to be used in each case depends on the Properties of the emulsion itself, namely its specific tendency to fog. Bigger ones Amounts of antifoggant other than those mentioned above no longer provide any further benefits; lesser Quantities lead to insufficient stabilization. It is also pointed out that even no desensitization occurs with considerable amounts.
Die erfindungsgemäße Emulsion zeichnet sich durch besondere Stabilität auch bei trockener oder feuchter Wärme aus; die Empfindlichkeit auch gegenüber größeren Wellenlängen ist nicht herabgesetzt; die Farbtrennung ist auch beim farbphotographischen übertragungsverfahren einwandfrei.The emulsion according to the invention is characterized by particular stability even when it is dry or moist heat from; the sensitivity to longer wavelengths is not reduced; the color separation is perfect even with the color photographic transfer process.
Die erfindungsgemäßen Antischleiermittel lassen sich insbesondere in solchen Emulsionen anwenden, in denen'anliegend an die aus der erfindungsgemäßen Silberhalogenidemulsion hergestellte Schicht eine Schicht mit einem Farbkuppler vorliegt, z. B. Substanzen mit einer entwickelnden Hydrochinoyl-, o-Dihydroxyphenyl- oder o- oder p-aminosubstituierten Hydroxyphenylgruppe. Im allgemeinen handelt es sich hierbei um Substanzen mit Benzolstruktur, die bei der Oxydation in eine Chinonstruktur übergehen. The antifoggants according to the invention can be used in particular in such emulsions in which one adjoins the layer produced from the silver halide emulsion according to the invention Layer with a color coupler is present, e.g. B. Substances with a developing hydrochinoyl, o-dihydroxyphenyl or o- or p-amino-substituted hydroxyphenyl group. Generally acts These are substances with a benzene structure that transform into a quinone structure during oxidation.

9% Gelatine wurden 12 ml destilliertes Wasser, 2 ml der 0,5gewichtsprozentigen methanolischen Lösung des Antischleiermittels, 1,5 ml 10%ige Saponinlösung und 1,5 ml lOgewichtsprozentige Natriummethyloleyl-taurat-Lösung zugesetzt, das Ganze 5 Minuten bei 38 0C gerührt und auf einen Celluloseacetatträger aufgebracht.9% gelatin, 12 ml of distilled water, 2 of 0,5gewichtsprozentigen methanolic solution of the anti-fogging agent, 1.5 ml of 10% saponin and 1.5 ml lOgewichtsprozentige ml Natriummethyloleyl taurate solution was added, the whole was stirred for 5 minutes at 38 0 C. and applied to a cellulose acetate support.
Das so enthaltene Aufzeichnungsmaterial wurde in einem Standard-Sensitomeier belichtet und 105 Sekunden mit einem Entwickler, enthaltend im Liter 3 g Monomethyl-p-aminophenolsulfat, 45 g Natriumsulfit, 12 g Hydrochinon, 80 g Natriumcarbonatmonohydrat und 2 g Kaliumbromid, entwickelt.The recording material contained in this way was exposed in a standard Sensitome egg and 105 Seconds with a developer containing 3 g of monomethyl-p-aminophenol sulfate, 45 g of sodium sulfite per liter, 12 g hydroquinone, 80 g sodium carbonate monohydrate and 2 g potassium bromide.
Das Aufzeichnungsmaterial wurde einerseits gleich nach Fertigstellung, andererseits nach einer Lagerzeit von einer Woche bei 490C Lagertemperatur, geprüft.The recording material was tested immediately after completion, on the one hand, and after a storage time of one week at a storage temperature of 49 ° C., on the other hand.
In folgender Tabelle sind zunächst vier erfindungsgemäße Antischleiermittel mit ihrer Konzentration, bezogen auf Silber, aufgeführt und die Ergebnisse hinsichtlich maximaler Dichte und Schleier gleich nach der Fertigstellung und nach einer Lagerzeit von einer Woche bei 490C enthalten. Aus der Differenz der Eigenschaftsverschlechterung bei der Lagerung ergibt sich die Überlegenheit der erfindungsgemäßen Antischleiermittel gegenüber vier nachfolgenden, strukturell verwandten Vergleichssubstanzen. In the following table are initially four anti-fogging agents according to the invention with its concentration, based on silver, and contain the results listed with regard to maximum density and fog immediately after completion and after a storage time of one week at 49 0 C. The difference in the deterioration in properties on storage results in the superiority of the antifoggants according to the invention over four of the following, structurally related comparison substances.
