Abstract
Claims (11)
- Elément photographique aux halogénures d'argent inversible comprenant un support portant au moins une couche d'émulsion photographique aux halogénures d'argent, l'émulsion photographique aux halogénures d'argent comprenant un milieu dispersant et un halogénoiodure d'argent photographique qui(a) est un halogénoiodure d'argent à coeur et à coque, à effet négatif, dans lequel le coeur n'est pas sensibilisé chimiquement,(b) a une teneur totale en iodure comprise entre 0,5 et 8 moles% ; et(c) dans lequel l'halogénoiodure d'argent a une fraction volumique de la coque (Vs) qui est supérieure à 0,05 mais inférieure ou égale à une constante (A) fois la teneur totale en iodure en moles% (It) dans lequel A est un paramètre sans unité égal à 0,15.
- Elément inversible selon la revendication 1, dans lequel l'halogénoiodure d'argent est le bromoiodure d'argent.
- Elément inversible selon la revendication 1, dans lequel l'halogénoiodure d'argent comprend des grains de bromoiodure d'argent octahédriques.
- Elément inversible selon la revendication 1, dans lequel l'halogénoiodure d'argent a une taille de grain moyenne comprise entre 0,3 et 1,0 µm.
- Elément inversible selon la revendication 1, dans lequel l'halogénoiodure d'argent est un bromoiodure d'argent ayant une teneur totale en iodure comprise entre 2 et 6 moles%.
- Elément inversible selon la revendication 1, dans lequel le milieu dispersant est la gélatine ou un dérivé de la gélatine.
- Elément photographique aux halogénures d'argent inversible selon la revendication 6, qui est un élément photographique aux halogénures d'argent inversible en couleurs.
- Elément inversible selon la revendication 1, comprenant un support portant des couches d'émulsions pour enregistrer séparément la lumière bleue, la lumière verte et la lumière rouge.
- Elément inversible selon la revendication 8, comprenant au moins une couche sensible au bleu, contenant au moins un coupleur formateur d'image de colorant jaune, au moins une couche sensible au vert contenant un coupleur formateur d'image de colorant magenta et au moins une couche sensible au rouge contenant au moins un coupleur formateur d'image de colorant cyan.
- Traitement inversible pour la formation d'une image dans un élément photographique aux halogénures d'argent inversible exposé tel que défini à la revendication 1, comprenant, dans l'ordre, les étapes qui consistent à développer l'élément dans un premier révélateur noir et blanc, laver l'élément dans l'eau, traiter l'élément obtenu dans une solution de traitement inversible pour rendre développables les halogénures d'argent non exposés ; développer l'élément obtenu dans un développateur chromogène ; et blanchir puis fixer l'élément.
- Traitement inversible pour la formation d'une image dans un élément photographique aux halogénures d'argent inversible exposé tel que défini à la revendication 9, comprenant, dans l'ordre, les étapes consistant à développer l'élément dans un premier révélateur noir et blanc, laver l'élément dans l'eau, traiter l'élément obtenu dans une solution de traitement inversible, développer l'élément obtenu dans un développateur chromogène ; et blanchir puis fixer l'élément.
