ABSTRACT:
An inorganic system of color photography in which colored images are recorded with compositions comprising a mixture of an iridescent pigment of the type displaying an interference-reinforced reflection color, and finely divided particles of a photosensitive material, such as a silver halide, which can be developed to give black or other light absorbing particles which will absorb light wavelengths complementary to the interference-reinforced reflection color of the iridescent pigment. The system does not require organic dyes in the final image, which is highly light-stable, and uses much smaller amounts of silver than conventional black and white photography.
