Abstract
Description
Die Erfindung betrifft ein einteiliges Bleichfixierbadkonzentrat (BX-Konzentrat), mit dem Bleichfixierbäder angesetzt bzw. regeneriert werden können.The invention relates to a one-piece bleach-fixing bath concentrate (BX concentrate), with bleach-fix baths can be prepared or regenerated.
BX-Bäder werden im farbfotografischen Verarbeitungsprozess eingesetzt, um das durch die Entwicklung entstandene metallische Silber zu einer löslichen Form zu oxidieren (Bleichung) und in dieser Form zusammen mit nicht entwickeltem Silber halogenid durch Komplexbildung aus dem Material zu lösen (Fixierung). BX-Bäder enthalten für diese Aufgaben eine Reihe notwendiger Chemikalien, nämlich ein Eisen (III)-komplexsalz als Oxidationsmittel, ein Thiosulfat als Fixiermittel und ein Sulfit, Disulfit oder eine Sulfinsäure als Stabilisator für das Thiosulfat, die sich gegenseitig beeinflussen, so dass sie nicht längere Zeit in der gleichen Lösung gehalten werden können. Zum Beispiel oxidiert das Eisen(III)-komplexsalz das Sul fit, Disulfit oder die Sulfinsäure. Dadurch entfällt die Stabilisierung des Thiosulfates, das sich dann zersetzt.BX baths are used in the color photographic processing process to achieve this metallic silver created by the development into a soluble form oxidize (bleaching) and in this form together with undeveloped silver to release halide from the material by complex formation (fixation). BX baths contain a number of chemicals necessary for these tasks, namely a Iron (III) complex salt as an oxidizing agent, a thiosulfate as a fixing agent and a Sulfite, disulfite or a sulfinic acid as a stabilizer for the thiosulfate, which itself influence each other so that they are not in the same solution for long periods of time can be held. For example, the iron (III) complex salt oxidizes the sul fit, disulfite or the sulfinic acid. This eliminates the need to stabilize the thiosulfate, which then decomposes.
Aus diesem Grund werden BX-Bäder zwei- oder dreiteilig konfektioniert, wobei die Teile erst unmittelbar vor dem Gebrauch vereinigt werden. Ebenso werden Konzen trate, die zum Regenieren, d. h. zum Nachdosieren verbrauchter Chemikalien benötigt werden, zwei- oder dreiteilig konfektioniert.For this reason, BX baths are made up in two or three parts, the Parts are only combined immediately before use. Likewise, concessions kicked to regenerate, d. H. needed to replenish used chemicals are made up in two or three parts.
Die mehrteilige Konfektionierung der Bestandteile einer BX-Tankfüllung oder eines BX-Regenerators ist nachteilig, weil sie einerseits aufwendig und unökonomisch ist, andererseits aber auch immer wieder zu Dosierungsfehlern führt.The multi-part assembly of the components of a BX tank filling or one BX regenerators are disadvantageous because, on the one hand, they are complex and uneconomical, on the other hand, it also leads to dosing errors.
Es besteht daher ein großer Bedarf, die Chemikalien für BX-Bäder einteilig zu kon fektionieren und insbesondere ein einteiliges BX-Konzentrat bereitzustellen, das in einfachster Weise durch Verdünnen mit Wasser zum gebrauchsfertigen BX-Bad umgesetzt oder ebenso einfach zum Regenerieren eines BX-Bad eingesetzt wird. There is therefore a great need to mix the chemicals for BX baths in one piece assemble and in particular to provide a one-piece BX concentrate, which in easiest by diluting with water to the ready-to-use BX bath implemented or just as easily used to regenerate a BX bath.
Es wurde nun überraschend gefunden, dass diese Aufgabe dadurch gelöst werden kann, dass man als Eisenspender ein Komplexsalz des zweiwertigen Eisens einsetzt und beim Ansetzen der BX-Tankfüllung einen Starter hinzugibt, der die Aufoxida tion des Fe(II)-komplexsalzes zum Fe(III)-komplexsalz in Gang setzt.It has now surprisingly been found that this object is achieved in this way can use a complex salt of divalent iron as an iron donor and when starting the BX tank filling adds a starter that the Aufoxida tion of the Fe (II) complex salt to the Fe (III) complex salt starts.
Fe(III)-komplexsalze, die sich für fotografische Bleich- und Bleichfixierbäder eig nen, sind aus einer Vielzahl von Dokumenten bekannt (z. B.

Gegebenenfalls kann der Regenerator auch vor dem Einsatz z. B. mit Luft, Sauerstoff, Wasserstoffperoxid oder Peroxid freisetzenden Substanzen aufoxidiert werden.Oxidation in the regenerator takes place during the batch, during the standing time in the regenerator, when the regenerator enters the tank and through the um pumping in the tank instead. If necessary, the regenerator can also be used e.g. B. with air, oxygen, hydrogen peroxide or peroxide releasing substances be oxidized.
