Gegenstand der Erfindung ist ein Verfahren zur Herstellung der für photographische Entwickler- und Fixierbäder verwendeten Stoffe. Die Erfindung besteht darin, daß zur Regelung des Waschens der phötographischen. Platten, Filme oder Papierabzüge den für das. photographische Verfahren erforderlichen Chemikalien ein wasserlöslicher Farbstoff hinzugesetzt wird, welcher die das Bild tragende Schicht 'vorübergehend färbt und durch Waschen erst dann wieder gänzlich entfernt wird, wenn die für die Erhaltung des Bildes schädlichen Chemikalien vollständig beseitigt sind.The invention relates to a process for the production of photographic materials Developing and fixing baths used substances. The invention consists in that to regulate the washing of the photographic. Plates, films or paper prints for use in the photographic process A water-soluble dye is added to the required chemicals, which the layer carrying the picture temporarily colors and only then again by washing It is completely removed if the chemicals harmful to the preservation of the image are completely eliminated.

Jeder Photograph kennt die Schwierigkeit, festzustellen, wann das Bild, sei es Platte, Film oder Papierabzug, genügend gewaschen . worden ist, um die Stoffe (beispielsweise Natrium, Hyposulfit) zu beseitigen, die sonst das Bild bei der Aufbewahrung verderben würden. Durch die Erfindung wird diese Schwierigkeit in der einfachsten Weise behoben, indem der dem Stoff hinzugesetzte Farbstoff, z. B. eine Anilinfarbe, so gewählt und in solcher Menge genommen wird, daß die hervorgerufene Färbung zugleich mit den letzten. Spuren des schädlichen Produktes verschwindet. . Zweckmäßig wählt man für die verschiedenen Produkte abweichende Farben, um jeden Irrtum bei ihrer Verwendung zu vermeiden.Every photographer knows the difficulty of determining when the picture, be it plate, Film or paper print, washed enough. has been used to remove the substances (e.g. sodium, Hyposulfite), which otherwise spoil the picture when stored would. The invention solves this problem in the simplest way, by the dye added to the fabric, e.g. B. an aniline dye, is chosen and taken in such an amount that the color that has been evoked at the same time as the last. Traces of the harmful product disappears. . It is advisable to choose different ones for the various products Colors to avoid any mistake in their use.

Zweckmäßig wird die Erfindung in der 'Weise ausgeführt, daß die in Betracht kommenden Chemikalien und der Farbstoff mit einer viskosen Flüssigkeit, die in Wasser löslieh ist, z.. B. Zuckersirup, Glukose, Glyzerin, alkalische Silikate, Alaun-oder Gemische, oder mit irgendeinem anderen Stoff, sei er je nach den Erfordernissen sauer, alkalisch oder neutral, der die Pastenform für eine unbegrenzte Zeit beibehält, vermengt. Das Gemisch wird durch Zerreiben und Kneten erzeugt. Man erzielt hierbei eine Masse von größerer oder geringerer Konsistenz, je nach den gewählten Bestandteilen. Der dem photographischen 45_ Zwecke dienende Stoff verteilt sich über die ganze Masse, wobei jeder kleinste Teil von der sirupartigen Masse umgeben ist. Der Stoff wird hierdurch vor der atmosphärischen Luft geschützt, so daß er sehr haltbar wird.The invention is expediently carried out in such a way that those in question Chemicals and the dye with a viscous liquid that dissolves in water is, for example, sugar syrup, glucose, glycerine, alkaline silicates, alum or mixtures, or with any other substance, be it acidic, alkaline or neutral, depending on the requirements, which maintains the paste form for an indefinite period of time. The mixture will generated by grinding and kneading. One achieves a mass of greater or lower consistency, depending on the ingredients chosen. The photographic 45_ Purpose-serving substance is distributed over the whole mass, with every smallest part of surrounded by the syrupy mass. The fabric is thereby in front of the atmospheric Air protected so that it is very durable.

Das beschriebene Verfahren läßt sich selbstverständlich für alle in Frage kommenden photographischen Stoffe, auch für Natriumsulfat, Natriumkarbonat, Natriumhyposulfit USM-. verwenden.. Für Gemische dieser Stoffe ' kann das Verfahren ebenfalls Verwendung finden. Solche Gemische werden zwecks Erzeugung des gewünschten Bades einfach aufgelöst. The method described can of course be used for all photographic materials in question, including sodium sulfate, sodium carbonate, sodium hyposulfite USM-. use .. For mixtures of these substances' the method can also be used. Such mixtures are used for the purpose of production of the desired bath simply dissolved.

Natürlich werden die sirupartigen oder viskosen Stoffe, die als Träger für die Chemikalien dienen, so gewählt, daß sie einen schädlichen Einfluß auf die Chemikalien nicht ausüben. Of course, the syrupy or viscous substances act as carriers for the chemicals are chosen so that they do not have a harmful influence on the chemicals.
