Abstract

L'invention concerne la photothermographie. Le procédé pour la préparation d'une composition photothermographique consiste à mélanger successivement, en les ajoutant dans l'ordre indiqué, 1 une dispersion comprenant un composé mercapto et un sel argentique d'une thione hétérocyclique, 2 une solution d'agent réducteur, 3 un liant et 4 une composition photosensible aux halogénures d'argent contenant un colorant sensibilisateur spectral. Application à l'obtention d'un produit photothermographique de sensibilité spectrale améliorée.
