ABSTRACT:
An image-forming agent selected from polyacids of molybdenum and tungsten and salts and complexes of these polyacids and disposed as a layer on at least one surface of a support substrate is reduced thereby being caused to undergo coloring in the form of an image and is then irradiated over its entire surface including thus colored parts and yet uncolored parts with long wavelength light rays which are absorbable by only the colored parts thereby to produce a colored image wherein the optical density of only the colored parts is selectively increased to a remarkable degree.
