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. A reverse photographic process for producing positive photographic images by imagewise exposure of the at least one silver halide emulsion layer contains light-sensitive material, black and white initial development of the material, chemical fogging or diffuse second exposure and subsequent color development, characterized in that
  • 1. only at least one N, N-dialkyl-p-phenylenediamine derivative is used as a developer in the initial development,
  • 2. the first development bath contains at least one compound which prevents coupling of the developer oxidation product formed during the first development with the color couplers in the color photographic reversal material to form image dyes,
  • 3. the silver halide emulsion layers of the photographic material have a chloride content of at least 80 mol%,
    • proves to be particularly suitable for the rapid development of reversal materials by eliminating or shortening the washing step between the first and second developer, without any disadvantages in terms of the quality of the color images produced by this process.
