Abstract

L'invention concerne l'industrie de la photographie. Procédé de fabrication d'émulsions photographiques par addition d'halogénure d'argent à une dispersion d'un acide gras à longue chaîne, à l'état fondu, dans l'eau, en l'absence de sels ammoniacaux ou alcalins de l'acide. Application à la formation de feuilles photothermographiques.
