Abstract

L'invention concerne la photographie. Les compositions photosensibles selon l'invention contiennent des grains d'halogénures d'argent aptes à former une image latente interne qui comprennent, adsorbé à leur surface, un agent de nucléation hétérocyclique de la classe du N-(acyl-hydrazino-phényl)thioamide. Application à l'obtention de produits améliorés donnant des images positives directes et, particulièrement, de produits composites pour la photographie par diffusion-transfert.
