Description

Verfahren zur Herstellung lichtempfindlicher Präparate zur Verfertigung von Lichtbildern. Es wurde gefunden, daß man zur Herstellung von Lichtbildern geeignete lichtempfindliche Präparate in einfacher Weise dadurch erhalten kann, daß man Eisenkarbonyl mit oder ohne Verwendung von Bindemitteln oder Trägern auf Unterlagen verschiedener Art, z. B. Papier, Glas, Filmen, porösen Massen u. a., aufbringt. Die so erhaltenen Präparate zeichnen sich durch erhebliche Lichtempfindlichkeit aus. Nach der Belichtung haben die belichteten Stellen eine dunklere Färbung angenommen.Method of making photosensitive preparations for manufacturing of photographs. It has been found that they are suitable for the production of photographs light-sensitive preparations can be obtained in a simple manner by iron carbonyl with or without the use of binders or carriers on substrates of various types Kind, e.g. B. paper, glass, films, porous masses and others. The so obtained Preparations are characterized by their considerable sensitivity to light. After exposure the exposed areas have taken on a darker color.

Es wurde weiterhin gefunden, daß man diese Lichtbilder in einfacher Weise dadurch fixieren kann, daß man sie mit Flüssigkeiten, «-ie Wasser, Benzol, Alkoholen, Benzin usw.. behandelt, welche das unbelichtete Eisenkarbonyl entfernen. Dabei tritt gleichzeitig eine Verstärkung des Farbtons der belichteten Stellen ein. Man kann außerdem den Farbton verändern, indem man das Bild mit anderen Stoffen behandelt, -welche den durch die Belichtung erzeugten Niederschlag umwandeln. So ruft z. B. Behandeln tnit saurer Ferrocyankaliumlösung eine blaue Färbung, solche mit verdünnter Gallussäure eine schwarze Färbung hervor. Beispiel: Ungeleimtes Papier wird mit Eisenkarbonyl getränkt und bei Zimmertemperatur im Dunkeln getrocknet. Nach der Belichtung wird die Kopie mit Benzol behandelt unrl getrocknet. Die belichteten Stellen erscheinen braun auf weißem Grunde.It has also been found that these photographs can be obtained more easily Can be fixed by using liquids, such as water, benzene, Alcohols, gasoline, etc. treated, which remove the unexposed iron carbonyl. At the same time, the hue of the exposed areas is intensified. You can also change the hue by mixing the image with other fabrics treated, -which convert the precipitation generated by the exposure. So calls z. B. Treat a blue coloration with an acidic ferrocyanic potassium solution, such a black color appears with dilute gallic acid. Example: Unsized paper is soaked in iron carbonyl and dried in the dark at room temperature. After exposure, the copy is treated with benzene and dried. The exposed Spots appear brown on a white background.
