  Photographisches Papier mit Schutzschicht. 



   Photographische Papiere müssen bekanntlich eine sehr reine Beschaffenheit haben und sind   daher verhältnismässig   teuer. Sie werden in der Regel mit Schutzschichten, wie Stärke, Gelatine u. dgl. überzogen, um die im Papier etwa noch vorhandenen schädlichen Beimengungen von der lichtempfindlichen Emulsionsschicht fern zu halten. 



   Die vorliegende Erfindung bezieht sich auf ein photographisches Papier mit Schutzschicht und besteht darin, dass als Schutzschicht eine dünne Papierlage benutzt wird, welche mit der unteren   Papierlag,   die dem ganzen   photographihchen   Papier den nötigen Körper gibt, in irgend einer Weise, beispielsweise vermittels   eines Kiebestoffes verbunden wird.   



  Ein derartiges photographisches Papier, welches also aus zwei miteinander   verbundenen   Papierlagen besteht, bietet den Vorteil, dass   man   für   einen   Teil   des zur herstellung des@   selben erforderlichen Papierstoffes, nämlich für die Unterlage, unabhängig von der   Reinheit   und der Zusammensetzung wird, wodurch der Preis des fertigen Papieres bedeutend ermässigt wird.

  Photographic paper with a protective layer.



   As is well known, photographic papers must have a very pure quality and are therefore relatively expensive. They are usually covered with protective layers such as starch, gelatin and the like. Like. Coated in order to keep any harmful additions still present in the paper away from the light-sensitive emulsion layer.



   The present invention relates to a photographic paper with a protective layer and consists in that a thin paper layer is used as the protective layer, which is connected to the lower paper layer, which gives the entire photographic paper the necessary body, in some way, for example by means of a glue becomes.



  Such a photographic paper, which thus consists of two paper layers connected to one another, offers the advantage that for part of the paper material required for the production of the same, namely for the base, one becomes independent of the purity and the composition, whereby the price of the of finished paper is significantly reduced.
