Abstract

Photographische Silberhalogenidmaterialien für die Erzeugung von Bildern mit ultrasteiler Gradation durch Schnellentwicklung, die Hydrazinverbindungen enthalten, müssen bei relativ hohen pH-Werten entwickelt werden. Dementsprechend ist die Stabilität der Entwicklerlösungen unzureichend.
Eine neue Klasse von Arylhydraziden mit einer kationischen Gruppe im Acylrest ermöglicht die Herstellung von Materialien, die bei relativ niedrigem pH-Wert schnell zu ultrasteiler Gradation entwickelt werden können.
Reproduktionstechnik, insbesondere Aufrastern von Halbtonbildern.
