ABSTRACT:
A camera-speed color photothermographic imaging method is disclosed. A photothermographic film is employed that contains a photographically responsive, thermally developable panchromatically sensitized emulsion layer unit capable of concurrently forming silver and dye image densities. The emulsion layer unit is exposed in three separate image capture areas to blue, green or red light received from the photographic subject to create latent images of blue, green and red light exposure. The photothermographic element is thermally processed to produce images of the same hue in each of the three separate image capture areas. The images of blue, green and red light exposures are then converted into a corresponding additive or subtractive primary hue, and integrated to provide a positive or negative color image of the photographic subject.
