| 摘要 |
The present invention is directed to a photothermographic imaging element comprising at least one silver halide imaging layer containing a fluorophore. The imaging element can be exposed and then processed by heating to form an image in which the intensity of the fluorescence from the element is modulated imagewise to yield a fluorescent image of the light intensities to which the element was exposed. The present invention is also directed to a method of processing photothermographic film that has been imagewise exposed in a camera, which method in order comprises thermally developing the film step without any externally applied developing agent, comprising heating said film to a temperature greater than 80° C., preferably in an substantially dry process, and detecting the luminescence latent image emitted by a fluorescent dye associated with at least one imaging layer and, based thereon, providing a digital electronic record, wherein substantial amounts or all of the silver and silver halide salts in the film are not removed before detection. A preferred embodiment of the invention is directed to a color photothermographic film.
