Description

Photographisches Diapositiv- und Reproduktionsmaterial. Die bisher verwendeten Träger für Diapositivschichten sind entwdder -durchsichtig wie Glas oder Zelluloid oder durchscheinend wie Milchglas. Eine Kolorierung der auf diesem Material hergestellten Diapositive konnte nur von der Vorderseite aus, d. h. durch Auftrag der Farbe auf das Bild selbst, ausgeführt werden, da einerseits die wäßrige Farblösung auf der Rückseite nicht haftete und anderseits die auf der Rückseite der Milchglasplatte etwa aufgebrachten Färbungen bis zur Vorderseite nicht durchscheinen. Durch diesen Farbauftrag auf der Bildseite werden jedoch die feinen Bilddetails verdeckt, wodurch eine ganz erhebliche Benachteiligung des beabsichtigten Effekts eintritt. Ebenso war es auch nach den .bisher bekannt gewordenen Verfahren (s. z. B. die deutsche Patentschrift 812q.6) nicht möglich, zu einem Material zu gelangen, welches zur Herstellung von Reproduktionen und Diapositiven, die auf der Rückseite ohne weiteres -bemalt werden können, in der Praxis geeignet ist, weil hiernach zunächst eine Photographie auf abziehbarem Material hergestellt und dann erst auf sehr umständliche Weise mit mehreren Gelatineschichten überzogen werden muß.Photographic transparencies and reproductive materials. The so far The supports used for slide layers are either transparent like glass or celluloid or translucent like frosted glass. A coloring of the one on this one Slides made from the material could only be viewed from the front, i.e. H. by Application of the color to the picture itself, as on the one hand the aqueous Color solution on the back did not adhere and the other on the back Any colorings applied to the frosted glass plate do not show through to the front. However, this application of paint to the picture side makes the fine picture details more visible hidden, whereby a very considerable disadvantage of the intended effect entry. It was the same after the previously known procedures (see e.g. B. the German patent specification 812q.6) not possible to get to a material, which for the production of reproductions and slides that are on the back can easily be painted, is suitable in practice, because after that first a photograph made on removable material and only then on very cumbersome Way must be coated with several layers of gelatin.

Es wurde nun ein photographisches Diapositiv- und Reproduktionsmaterial gefunden, das die oben erwähnten Nachteile beseitigt, so daß es für die Herstellung von farbigen Bildern, welche keine Unterdrückung der Details aufweisen, ohne weiteres geeignet ist.It now became a photographic slide and reproductive material found that eliminates the above-mentioned disadvantages, making it suitable for manufacture of colored images that do not have any suppression of details, without further ado suitable is.

Für dieses neue photographische Dia.-positiv- und Reproduktionsmaterial wird als Unterlage für die lichtempfindliche Emulsion eine mit einem durchscheinenden Pigment versehene, zweckmäßik nicht über 0,3 mm dicke Folie verwendet, welche auf der Rückseite eine für den Auftrag von Farbstoffen oder Farbpigmenten geeignete Gelatineschicht trägt, d'i'e gleichzeitig ein Rollen des Materials bei seiner Verarbeitung verhindert: -Beispiel. Eine Azety lzelluloselösung wird mit photographischem Barytweiß, das zu einer alkoholfeuchten Paste verrührt ist, vermengt und in der üblichen Weise filtriert. Aus der homogenen Masse wird in bekannter Weise eine nicht über 0,3 mm dicke Folie hergestellt und diese auf der einen Seite mit einer Emulsionsschicht, auf der anderen Seite mit einer zweckmäßig gehärteten Gel.atineschicht versehen. For this new photographic slide positive and reproduction material, a film provided with a translucent pigment, expediently not more than 0.3 mm thick, is used as a base for the light-sensitive emulsion, on the back of which a gelatin layer suitable for the application of dyes or color pigments is used carries, d'i'e at the same time prevents the material from rolling during its processing: -Example. An acetyl cellulose solution is mixed with photographic barite white, which has been mixed to form an alcohol-moist paste, and filtered in the usual way. A film not more than 0.3 mm thick is produced from the homogeneous mass in a known manner and this is provided on one side with an emulsion layer and on the other side with an appropriately hardened gelatin layer.

An Stelle des genannten Pigments können auch andere derartige Pigmente, wie Ocker oder andere Erdfarben oder mit Farbstoffen angefärbte Pigmente, Verwendung finden. Ebenso kann die Azetylzelluloselösung durch eine andere Zellulosederivatlösung, wie Äthylzelluloselösung; Benzylzelluloselösung, Nitrozelluloselösung usw., ersetzt werden.Instead of the pigment mentioned, other such pigments, such as ocher or other earth colors or pigments colored with dyes, use Find. The acetyl cellulose solution can also be replaced by another cellulose derivative solution, how Ethyl cellulose solution; Benzyl cellulose solution, nitrocellulose solution etc., to be replaced.
