Description

Verfahren zur Desensibilisierung von lichtempfindlichen Halogensilberschichten durch Anthrachinonabkömmlinge Es ist bekannt, zur Desensibilisierung von photographischen Emulsionen Anthrachinonderivate zu verwenden. So sind als besonders wirksam bekannt Tauride der Anthrachinonsulfo- bzw. Caxbons:äuren bzw. Anthrachinonsäureamine, in deren Amidogruppen mindestens ein Wasserstoffatom durch einen Sulfo-oder Carboxylgruppen tragenden Restersetzt ist. Nach Patent 68o o93 zeigen ferner besonders :die Äther und Thioäther des Anthrachinons 'mit aliphatischen und aromatischen Resten gute Diesensibilisierungseigenschaften.Process for the desensitization of photosensitive halogen silver layers by anthraquinone derivatives It is known for the desensitization of photographic To use emulsions anthraquinone derivatives. So are known to be particularly effective Taurides of the anthraquinone sulfo- or caxbons: acids or anthraquinonic acid amines, in their amido groups have at least one hydrogen atom through a sulfo or carboxyl group load-bearing residue is replaced. According to patent 68o 093 also show in particular: the ethers and thioethers of anthraquinone with aliphatic and aromatic residues are good These sensitizing properties.

Es -wurde nun gefunden, daß miau allgemein die Eigenschaften der Diesensibilisatorendieser Klasse verbessern kann, wenn man Abkömmlinge von Anthrachinon verwendet, ;die durch .carbücyclische Kondensation mit einem Triazol entstanden sind, wie z. B. Anthrachinontriazol, Anthrachinontriazolsulfosäure, Anthrachinontriazalcarbonsäure, Nitroanthrachinontriazol usw. Es zeigte sich, daß die Sulfos,äuren dieser neuen Körper gegenüber den bisher bekannten-Substanzen noch -weiter gesteigerte Wirkung besitzen. Gleichzeitig zeigen diese Stoffe eine sehr ;günstige Löslichkeit und ebenfalls Haltbarkeit der Lösungen und werden auch nicht durch Kalksalze ausgefällt.It has now been found that the properties of these sensitizers in general meow Class can be improved by using derivatives of anthraquinone; which by .carbücyclische condensation with a triazole have arisen, such as. B. Anthraquinone triazole, Anthraquinone triazole sulfonic acid, anthraquinone triazalcarboxylic acid, nitroanthraquinone triazole etc. It turned out that the sulfos acids of these new bodies compared to those previously known substances still have an increased effect. Show at the same time these substances have a very favorable solubility and also durability of the solutions and are not precipitated by calcium salts.

Diese Körper können natürlich sowohl ,als Vorbad wie als Entwicklerzusatz verwendet werden.These bodies can of course be used both as a pre-bath and as a developer additive be used.

Beispiel i o,5 g der i, 2-Tria.zoanthrachinon-3-sulfosäure werden in i 1 Entwickler gelöst. In diesem Entwickler werden - ortho- bzw. panchromatische photographische Schichten i bis 2 Minuten im Dunkeln entwickelt tmd können dann bei hellgrünen bzw. gelbem Licht zu Ende entwickelt werden.Example i o.5 g of i, 2-triazoanthraquinone-3-sulfonic acid become solved in i 1 developer. In this developer - ortho- or panchromatic Photographic layers can then be developed in the dark for up to 2 minutes can be fully developed in light green or yellow light.

Beispiel 2 o,3 g des ?, 3-Triazoanthrachinons werden in i 1 Entwickler gelöst. Die in diesem Entwickler entwickelten ortho- und panchromatischen Schichten können nach einer kurzem Entwicklung im Dunkeln bei hellgrünem oder gelbem Licht zu Ende entwickelt werden.Example 2 0.3 g of?, 3-triazoanthraquinone are used in 1 developer solved. The ortho- and panchromatic layers developed in this developer can after a short development in the dark in light green or yellow light to be developed to the end.
