  Verfahren zur Herstellung von Zwischenschichten für lichthoffreie Platten. 



   Im weiteren Verlauf der Untersuchungen über die Herstellung von Zwischenschichten bei   photographischen Platten, Films u.   s. w. zur Vermeidung von Lichthofbildung wurde gefunden, dass es noch zweckmässiger ist, an Stelle im Stammpatent beschriebenen Ferrozyanide des Urans und Molybdäns das Ferrozyankupfer zur Präparation bezüglicher Zwischenschichten zu verwenden. 



   Dadurch, dass Ferrozyankupfer eine mehr ins Rot gehende Farbe besitzt, bieten schon sehr diinne Schichten ausreichenden Schutz gegen Lichthöfe. 



   Zur Bereitung solcher Schichten werden Glasplatten mit einer   Lösung überzogen,   
 EMI1.1 
 starren badet man die Platten in einer hinreichend starken Lösung von Ferrozyanwasserstoffsiiure, wäscht kurz in Wasser und trocknet. Auf   die so präparirten Platten   wird alsdann die lichtempfindliche Emulsion aufgetragen. 

**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

  Process for the production of intermediate layers for aero-free panels.



   In the further course of the investigations into the production of intermediate layers in photographic plates, films and the like. s. w. To avoid halation, it has been found that it is even more expedient to use ferrocyanic copper instead of the ferrocyanides of uranium and molybdenum described in the parent patent for the preparation of intermediate layers.



   Because ferrocyan copper has a more red color, even very thin layers offer sufficient protection against halos.



   To prepare such layers, glass plates are coated with a solution,
 EMI1.1
 rigidly, the plates are bathed in a sufficiently strong solution of ferrocyanic acid, briefly washed in water and dried. The light-sensitive emulsion is then applied to the plates thus prepared.
