The once-imaged photosensitive material consists of two types of substrates. The first layer of the film base is a negative film, and its surface is coated with a silver halide sensitizer with a high silver content and a thin coating; the second layer film base is a positive film, and the surface is coated with a layer of activated carbon, sulfide, rubber, etc. Layers of composition. The two layers are separated by a plastic bag filled with a slurry. The syrup is made up of a developer fixer, a silver halide solvent, a rubber compound, and the like. After the negative film is exposed to light, the two bases are simultaneously pressed from a pair of rollers, the plastic bag is squeezed, and the slurry evenly coats the overlapping surfaces of the negative film and the positive film. A series of rapid chemical reactions occur between positive and negative films. In the emulsion layer of the negative film, the silver halide of the photosensitive portion is reduced to form metallic silver on the negative film; the silver halide of the unexposed portion is dissolved by the slurry, diffused to the receiving layer of the positive film, and the silver sulfide and other catalysts in the receiving layer are used as catalysts. Contact, reduced to metal silver, in the two-layer film base, forming what people need positive image. In this way, a photo is formed.
