PURPOSE:To make an image forming material usable as a dot resolving film, a lith film, etc. by forming a dot resolved image on a photosensitive silver emulsion layer on a photo-insolubilizable colored layer, irradiating active light to form an image on the colored layer, and dyeing the image. CONSTITUTION:A photo-insolubilizable water-soluble colored layer of gelatin or the like contg. a condensation product of a diazonium salt is formed on a transparent support of polyethylene terephthalate, polypropylene or the like. a photosensitive silver emulsion layer is formed on the colored layer with a strippable intermediate barrier layer in-between, and a dot image with >=2.5 optical transmission density I is formed on the emulsion layer. Active light is irradiated through the image, and the barrier layer, together with the silver salt image, is stripped. The resulting colored image with 0.5-1.5 density I is dyed with an aqueous dye soln. to form a dyed image with >=2.5 density I. |
