| abstract | 1454524 Photographic heat-processable silver halide materials KODAK Ltd 19 April 1974 [19 April 1973] 19028/73 Heading G2C Heat-processable photographic materials are made by forming a photo-sensitive silver halide emulsion by precipitating silver halide grains in an aqueous dispersion medium containing two peptizing agents (i) a polyoxyethylene surfactant having a hydrocarbon hydrophobic portion and at least one polyoxyethylene group bonded thereto through a hetero atom e.g. N or O and (ii) an anionic surfactant e.g. sodium lauryl sulphate, or a polymeric peptizing agent e.g. gelatin; and mixing the dispersion so obtained, if necessary after replacing the aqueous medium with an organic solvent, with a binder solution, e.g. of polyvinyl butyral; and then mixing the emulsion with an oxidation/reduction image-forming system comprising a light-insensitive reducible metal compound e.g. silver stearate or silver behenate and a reducing agent therefor e.g. a phenol or naphthol, and coating the mixture on a support, or coating the emulsion and the oxidation/reduction image-forming system in separate layers on the same side of the support. |
