Abstract

L'invention concerne la photothermographie. Le produit photographique thermodéveloppable selon l'invention, comprend un support et, en association réactive, au moins une couche thermodéveloppable A contenant 1 un halogénure d'argent photosensible, 2 au moins un développateur actif, 3 un précurseur d'activateur de développement, et 4 un liant polymère, et au moins une couche B contenant un colorant d'azoaniline qui, par développement thermique uniforme de l'image latente de la couche A, est blanchi dans les plages non insolées du produit. Application à l'obtention d'un produit photographique thermoéveloppable fournissant des images argentiques amplifiées par un colorant et protégées contre le halo.The invention relates to photothermography. The thermodevelopable photographic product according to the invention comprises a support and, in reactive combination, at least one thermodevelopable layer A containing 1 a photosensitive silver halide, 2 at least one active developer, 3 a development activator precursor, and 4 a polymeric binder, and at least one layer B containing an azoaniline dye which, by uniform thermal development of the latent image of layer A, is bleached in the non-exposed areas of the product. Application to obtaining a thermo-developable photographic product providing silver images amplified by a dye and protected against the halo.
