摘要：
The present invention is directed to a method of forming a positive image in a photothermographic element comprising a potentially negative-working emulsion wherein fog density development is imagewise inhibited in exposed areas of the image upon thermal development. In one embodiment of the invention, a density-inhibiting agent is released during thermal development which agent inhibits the thermal development of unexposed silver salts in the exposed areas relative to the unexposed areas. The method preferably comprises imagewise exposing the film with a non-solarizing amount of radiation/energy to form a latent image and thermally developing the latent image in a single development step to produce a positive image in the element. The present invention is also directed to a photothermographic element 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.
摘要（中）：
本发明涉及一种在光热敏成像元件中形成正像的方法，该光热敏成像元件包括潜在的负性乳液，其中在热显影时图像的暴露区域中的雾密度显影成像抑制。 在本发明的一个实施方案中，在热显影期间释放密度抑制剂，其中该试剂抑制相对于未曝光区域的曝光区域中未曝光的银盐的热显影。 该方法优选地包括以非日化量的辐射/能量成像曝光所述膜以形成潜像并在单个显影步骤中热显影所述潜像，以在所述元件中产生正像。 本发明还涉及一种光热敏成像元件，其可用于本发明的曝光和热加热至150℃以上时形成以高速和鉴别为特征的正像的方法。
