Abstract

Ein fotografisches Umkehrverfahren zur Herstellung von positiven fotografischen Bildern durch bildmäßige Be­ lichtung des mindestens eine Silberhalogenidemulsions­ schicht enthalten lichtempfindlichen Materials, Schwarzweiß-Erstentwicklung des Materials, chemische Verschleierung oder diffuse Zweitbelichtung und an­ schließende Farbentwicklung, dadurch gekennzeichnet, daß
  • 1. bei der Erstentwicklung ausschließlich mindestens ein N,N-Dialkyl-p-phenylendiaminderivat als Ent­ wickler verwendet wird,
  • 2. das Erstentwicklungsbad wenigstens eine Verbindung enthält, die eine Kupplung des bei der Erstent­ wicklung entstandenen Entwickleroxidationsproduktes mit den in dem farbfotografischen Umkehrmaterial befindlichen Farbkupplern zu Bildfarbstoffen ver­ hindert,
  • 3. die Silberhalogenidemulsionsschichten des foto­ grafischen Materials einen Chloridgehalt von min­ destens 80 Mol-% aufweisen,
    • erweist sich als besonders geeignet zur Schnellent­ wicklung von Umkehrmaterialien durch Wegfall oder Kür­ zung des Wässerungsschrittes zwischen Erst- und Zweit­ entwickler, ohne daß dadurch Nachteile bezüglich der Qualität der durch diesen Prozeß gefertigen Farbbilder auftreten.
