 insbesondere des Eisens. Nickels oder Kobalts erzielte Wirkung der Verhinderung der Schleierbildung beim Entwickeln unterbelichteter photographischer Platten o. dgl. wesentlich verbessert wird. wenn man ausserdem noch Anilin beifügt. 



   Der Zusatz von Anilin kann entweder mit dem Zusatze an Verbindungen der Metalle der Elementengruppe VIII in den Entwickler eingeführt und nachträglich zugefügt werden. Er bewirkt im Verein mit diesen Stoffen eine überraschend gute Verhinderung der Schleierbildung, ohne die Reduktionskraft des starken Entwicklers nachteilig zu beeinflussen.

  Method to prevent fogging and to reduce the exposure time without
Risk of fogging.
 EMI1.1
 especially of iron. Nickel or cobalt's effect of preventing fogging when developing underexposed photographic plates or the like is significantly improved. if you also add aniline.



   The addition of aniline can either be introduced into the developer with the addition of compounds of the metals of element group VIII and can be added subsequently. In combination with these substances, it produces a surprisingly good prevention of fogging without adversely affecting the reducing power of the strong developer.
