    • The present invention is directed to a method of forming a positive image in a photothermographic assembly comprising a photothermographic material and an intensifying means for converting ionizing radiation, wherein the assembly has been imagewise exposed to ionizing radiation to form a latent image in the photothermographic material. The photothermographic material has at least one imaging layer comprising a potentially negative-working emulsion, wherein thermal development of unexposed silver salts in exposed areas relative to unexposed areas is inhibiting when thermally developing the imagewise exposed assembly, thereby producing a positive image. The present invention is also directed to a photothermographic assembly that can be used in the present process in which a positive image characterized by high speed and discrimination is formed when exposed and thermally heated above 150° C.
    • 本发明涉及一种在光热敏成像组件中形成正像的方法,该光热敏成像组件包括光热成像材料和用于转换电离辐射的增强装置,其中该组件已成像地暴露于电离辐射以在光热敏成像材料中形成潜像。 光热敏成像材料具有至少一个成像层,该成像层包括潜在的负性乳液,其中相对于未曝光区域的曝光区域中未曝光的银盐的热显影在热显影图像曝光组件时被抑制,由此产生正像。 本发明还涉及一种光热敏成像组件,其可用于本发明的方法中,其中当暴露并热加热至150℃以上时,形成以高速和鉴别为特征的正像。
