Description

  

  Verfahren zur Herstellung farbiger Photographien.         Gemäss    dem Verfahren des Hauptpatentes  zur Herstellung farbiger     Photograpliierr    wan  delt man Silberbilder     zunächst    in Kupferton  bilder uni     und    färbt dieselben mit     solchen          organischen        Farbstoffen,    welche an den Kupfer  tonbildern     festhaften.    Man kann     nrrn    eine für  Farbbilder     etwa    notwendige     Verstärkung     dadurch erzielen,

   dass man bei zu     sehwacher     Färbung durch     nochmaliges        Badear    in     Farb-          atofflüsungen    eine Verstärkung     herbeiführt.     Die     Verstärkung    wird am besten erst nach  erfolgtem Trocknen     vorgenommen.  



  Process for making color photographs. According to the process of the main patent for the production of colored photograpliers, silver images are first converted into copper tone images and colored with organic dyes that adhere to the copper tone images. One can only achieve a reinforcement that may be necessary for color images by

   that if the coloration is too weak, one can bring about a reinforcement by repeated bathing in the dye. The reinforcement is best done after drying.
