Abstract

High-resolution photographic images are prepared by exposing a film composed of a metal-organic chelate polymer to a radiant energy source. The metal ion is reduced to its zero oxidation state. Metal-organic chelate polymers are prepared from polyethyleneimine and salts of tetracoordinate metals selected from Ag, Pt, Pd, Au, etc. The prepared polymer is coated by conventional methods onto a suitable substrate and exposed in a predetermined pattern to a radiant energy source. The radiant energy source is selected from visible light, ultraviolet light, infrared radiation, electron beam radiation, laser beam radiation and x-radiation. The energy source is of sufficient energy to cause the reduction of the metal ion to its metallic state.

Preparation and Process for Producing High Resolution Photographs

High-resolution photographic images are prepared by exposing a film composed of a metal-organic chelate polymer to a radiant energy source. The metal ion is reduced to its zero oxidation state. Metal-organic chelate polymers are prepared from polyethyleneimine and salts of tetracoordinate metals selected from Ag, Pt, Pd, Au, etc. The prepared polymer is coated by conventional methods onto a suitable substrate and exposed in a predetermined pattern to a radiant energy source. The radiant energy source is selected from visible light, ultraviolet light, infrared radiation, electron beam radiation, laser beam radiation and x-radiation. The energy source is of sufficient energy to cause the reduction of the metal ion to its metallic state. After exposure of the polymer film, the image is developed by removing the unexposed portions of the film in a suitable solvent.
