Abstract
Nouveaux produits et procédés photographiques. Le procédé consiste en les étapes d'exposition d'une unité de film photosensible comprenant une pluralité de couches y compris au moins un support supportant une couche d'halogénure d'argent photosensible, au moins une desdites couches contenant un précurseur d'agent de filtre optique essentiellement incolore activé à un pH alcalin pour former un agent de filtre optique coloré, ledit agent de filtre optique coloré après un temps prédéterminé a un pH alcalin prédéterminé formant un composé essentiellement incolore différent dudit précurseur ou dudit agent de filtre et non réversible en un de ceux-ci par changement de pH, de mise en contact de ladite couche photosensible et dudit précurseur avec une composition de traitement ayant un pH alcalin au moins aussi élevé que ledit pH alcalin prédéterminé pour initier le développement et effectuer la formation dudit agent de filtre optique et le maintien du pH de ladite composition de traitement en contact avec ledit agent de filtre optique à une valeur au moins aussi élevée que ledit pH alcalin prédéterminé au moins jusqu'à ce que ledit agent de filtre optique coloré ait été converti en ledit composé incolore.
