Abstract
L'invention concerne un procédé pour préparer des produits destinés à fournir simultanement des micro-images argentiques de fort contraste et des macro-images argentiques de contraste moins fort. Le procédé consiste à utiliser comme couche sensible un mélange comprenant : 1 degrés des grains d'halogéno-iodure formateurs d'image dont le taux d'iodure est compris entre 5/1000 et 10/100 en moles; 2 degrés des grains d'halogénure d'argent voilés en surface et développables indépendamment de l'exposition photographique comme s'ils avaient été exposés à un rayonnement d'intensité maximale. Application au microfilmage des documents et à la reproduction des documents ainsi microfilmés.
