Abstract

L'invention concerne un nouveau procédé de formation d'images photographiques. Pour former une image photographique comprenant une image argentique et une image de colorant, on développe un matériau photosensible à l'halogénure d'argent exposé en présence d'un dihydroxynaphtalène et d'une 3-pyrazolidone. On obtient des images de densité améliorée.
