ABSTRACT:
A method for producing a heat resistant, light resistant, chemically resistant and abrasion resistant noble metal image comprising forming a silver image on a photographic material which comprises a substrate having thereon at least one silver halide emulsion layer, either directly or on at least one subbing layer on the substrate, by exposing and developing the photographic material, converting the silver image into a noble metal image by contacting the silver image with a compound containing a noble metal having an ionization tendency smaller than the ionization tendency of silver, and then heating the photographic material in an oxygen-containing gas to thermally decompose and substantially remove the organic components on the substrate.
