Verfahren zur Herstellung metallisch wirkender photographischer Papiere.
Die Erfindung betrifft ein Verfahren zur Herstellung photographiseher Papiere, welche durch Metallglanz die Wirkung des Bildes erhöhen.
Es sind zwar Verfahren bekannt, welche ähnliche Zwecke anstreben. Dieselben wollen aber den metallischen Charakter durch einen Zusatz von Metallpulvern zur Gelatineschicht erreichen, welche dann gehärtet wurde. Durch dieses Verfahren konnte naturgemäss kein richtiger metallischer Charakter des Bildes erzielt werden, da der Metallstab immer deutlich den Charakter eines Anstriches zeigt.
Gemäss der Erfindung wird zwischen dem Papier und der photographisehen Emulsion eine Metallfolie eingelegt, welche durch einen gehärteten Albuminuberzug sowohl für die Papierunterlage als auch für die Emulsion gut haftend gemacht wurde.
Durch diese metallene Zwischenschicht wird nicht nur dem fertigen Lichtbilde ein vollkommen metallischer Charakter verliehen, sondern es wird das Bild auch gegen Feuchtigkeit sowie gegen das Verziehen oder Werfen geschützt, was namentlich bei grösseren Formaten von grossem Werte ist. Die Stärke der Metallfolie ist natürlich beliebig und nur von der gewünschten Festigkeit und Steifheit abhängig, da der erfindungsgemäss gewollte Zweck sowohl mit dünnen als auch dicken Folien erzielt wird.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Process for the production of photographic papers with a metallic appearance.
The invention relates to a process for the production of photographic papers which use metallic luster to increase the effect of the image.
Methods are known which aim at similar purposes. But they want to achieve the metallic character by adding metal powders to the gelatin layer, which was then hardened. Naturally, this process could not achieve a real metallic character of the picture, since the metal rod always clearly shows the character of a paint.
According to the invention, a metal foil is inserted between the paper and the photographic emulsion, which has been made adherent to both the paper base and the emulsion by a hardened albumin coating.
This metal intermediate layer not only gives the finished photograph a completely metallic character, but also protects the picture against moisture and against warping or throwing, which is particularly important in larger formats. The thickness of the metal foil is of course arbitrary and only depends on the desired strength and rigidity, since the purpose intended according to the invention is achieved with both thin and thick foils.
