Description

Verfahren zum Herstellen von photographischen Mehrfarbenbildern Die auf Papier hergestellten und gegebenenfalls vergrößerten Bromsilberauszüge für Rot und Blau werden in solche aus Silberkupferrhodanid (Beizkörper) verwandelt und nach dem Trocknen mit entsprechendem, in dünnem Syrup gelöstem Anilinfarbstoff (rot und blau) eingefärbt. Durch den Syrupzusatz wird das Einfärben des Papierfilzes vermieden. Nach kurzem Wässern erhält man dann wasserunlösliche Farbbilder mit reinen Weißen, die folgendermaßen im Register übereinandergedruckt werden: Die in Tanninlösung gegerbte Rotmatrize wird, Bildseite oben, auf eine Glasplatte gelegt, darauf in .genauer Deckung das Blaubild, Bildseite unten. Nachdem das Wasser leicht ausgedrückt ist, wird eine hochprozentige Natriumthiosulfatlösung auf die Rückseite der Blaumatrize aufgetragen. Im Ausgleich der Spannungsdifferenz zwischen der Natriumthiosulfatlösung und dem Wasser in Gelatineschicht und Papierfilz vollzieht sich folgendes: Der lichtunbeständige Beizkörper löst sich, dadurch wird auch die Färbe wieder löslich. Das obenauf liegende Blaubild wird der Flüssigkeitsbewegung nach in das rote übergedruckt. Das rote Teilbild nimmt infolge der Gerbung in Tannin wohl Farbstoff an, gibt aber keinen mehr ab. Nach etwa 15 Minuten ist dieser Vorgang beendet, und die nunmehr farblose Blaumatrize wird abgezogen. Danach wird das rotblauviolette Bild in schwacher Tanninlösung gewässert.Method of Making Multicolor Photographic Images Die Silver bromide extracts for red produced on paper and enlarged if necessary and blue are transformed into those made of silver copper rhodanide (pickling body) and gradually after drying with the appropriate aniline dye dissolved in a thin syrup (red and blue) colored. The addition of syrup prevents the paper felt from being colored. After a short soak, water-insoluble color images with pure whites are obtained, which are printed one on top of the other in the register: Those in tannin solution The tanned red matrix is placed, face up, on a glass plate, then in .precise coverage the blue picture, picture side below. After the water is easily squeezed a high percentage sodium thiosulphate solution is applied to the back of the blue die applied. In balancing the voltage difference between the sodium thiosulfate solution and the water in the gelatin layer and paper felt takes place as follows: The light-unstable The stain dissolves and the dye becomes soluble again. The one on top The blue image is overprinted in the red according to the movement of the liquid. The red part as a result of the tanning in tannin takes on dye, but does not give off any more. This process is over after about 15 minutes and the now colorless blue matrix is finished is withdrawn. Then the red-blue-violet picture is soaked in a weak tannin solution.

Für das gelbe Teilbild ist weder ein Negutiv noch eine Vergrößerung erforderlich. Da dem gelben Teilbild für die Bildzeichnung die geringste Bedeutung zukommt, wird dasselbe durch Handauftrag ergänzt (Ölfarbe, Spezialölmischung, Watte und Wischer). - Auf dieselbe Weise sind Farbe und Form zu retuschieren.The yellow partial image is neither a negative nor an enlargement necessary. Since the yellow partial picture is of the least importance for the picture drawing the same is supplemented by hand application (oil paint, special oil mixture, cotton wool and wiper). - Retouch the color and shape in the same way.

PATENTANSPRUCH: Verfahren zum Herstellen von photographischen Mehrfarbenbildern, dadurch gekennzeichnet, daß die roten und blauen Teilfarbenauszüge nach Umwandlung des Silbers in Silberkupferrhodanid mit in dünnem Syrup gelösten Anilinfarbstoffen angefärbt und im Register aufeinandergedruckt werden, worauf durch Behandeln des einen Teilfarbenauszuges mit Natriumthiosulfat von der Rückseite aus der Beizkörper in diesem gelöst wird, so daß der Farbstoff von ihm in das andere Bild übergeht.PATENT CLAIM: Process for producing multicolor photographic images, characterized in that the red and blue partial color separations after conversion of silver in silver copper rhodanide with aniline dyes dissolved in thin syrup colored and printed on top of each other in the register, whereupon by handling the a partial color extract with sodium thiosulphate from the back of the stain body is dissolved in this, so that the dye passes from it into the other image.
