摘要:
A photosensitive image forming medium coating solution is prepared by converting a water dispersion containing at least an organic silver salt, but substantially free of a photosensitive silver salt into a high pressure, high speed flow, causing a pressure drop of 900-3,000 kg/cm 2 to the flow, and then mixing the flow with a photosensitive silver salt. Using this aqueous coating solution, a photothermographic element having a low haze, low fog and high sensitivity can be produced with the advantages of environmental protection and low cost.

摘要:
A diffusion transfer film unit, containing a light-sensitive sheet, a transparent cover sheet, and a light-shielding alkaline processing composition, in which an adhesive layer and a peeling-agent layer are arranged so that they are adjacent to each other, the adhesive layer and the peeling-agent layer are disposed at a position closer to a light-exposure position than an image-receiving layer in the light-sensitive sheet or at any position in the transparent cover sheet, and the adhesive layer is disposed on the side closer to the image-receiving layer than the peeling-agent layer.
摘要:
A gas sensing material includes a nonphotosensitive organic silver salt. A gas inspecting method includes adhering a gas sensing material to a surface of an inspection object, wherein the gas sensing material includes a nonphotosensitive organic silver salt; and heat developing the gas sensing material.
摘要:
An internal latent image-type direct positive silver halide emulsion comprising a core/shell structure silver halide which is composed of a chemically sensitized core and a chemically sensitized shell and which is not prefogged, and a compound of formula (I): Formula (I) (X) k -(L) m -(A-B) n wherein X represents a light-absorbing group or a silver halide-adsorbing group having at least one atom selected from the group consisting of N, S, P, Se and Te; L represents a divalent linking group having at least one atom selected from the group consisting of C, N, S and O; A represents an electron-donating group; B represents a leaving group or a hydrogen atom, which leaves or undergoes deprotonation after being oxidized, to form a radical A • ; k and m each independently are an integer of 0 to 3; and n is 1 or 2. A color diffusion transfer light-sensitive material containing the emulsion.
