Abstract

L'invention est relative à l'électrophotothermographie, et plus particulièrement à un produit d'enregistrement à la fois formateur et récepteur d'image à structure intégrale multicouche. Ce produit comprend un support 1 portant une couche électriquement conductrice 2, éventuellement une couche adhésive 3, une couche semi-conductrice 4, et une couche sensible aux charges et thermo-développable 5, contenant un sel métallique réductible et un agent réducteur des ions argent. La figure montre un mode de réalisation dans lequel ce produit est associé à un dispositif comprenant un support transparent 10, portant une couche conductrice 9 et un transducteur opto-électrique 8. Le produit et le dispositif sont séparés par une lame d'air 7, et des dispositifs d'espacement 6. L'exposition a lieu sous une échelle sensitométrique 11, tandis qu'un courant électrique est appliqué simultanément aux couches conductrices 2 et 9, à partir d'une source 12. Application à l'obtention de produits d'enregistrement améliores, notamment pour la radiographie
