A heat-developable photosensitive material having: (a) at least one layer of photosensitive image-forming layer containing an organic silver salt, a photosensitive silver halide, a reducing agent and an organic binder; and (b) a functional layer containing a binder and a solid dispersion; the binder consisting of a water-dispersed thermoplastic resin, and the solid dispersion being made of a precursor of a photographically useful compound capable of releasing the photographically useful compound when heated to 100° C. or higher and not higher than heat development temperature is disclosed.
摘要:
Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer and an electrically-conductive layer comprising a dispersion in a film-forming binder of very small particles of antimony-doped tin oxide having a high antimony dopant level and a small crystallite size. Use of such particles provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.

摘要:
The present invention is a photographic element which includes a support having a front surface and a back surface, and a silver halide imaging layer superposed on the front side of the support. A backing layer is superposed on the backside of the support and is formed by the coating and subsequent drying of an aqueous coating composition having therein a mixture of film-forming colloidal particles and non-film-forming colloidal particles and a fluoropolyether comprising more than 90 mole % units selected from the group consisting of --CF.sub.2 --CF.sub.2 --O--, --CF.sub.2 --O--, --CF(CF.sub.3)--O--, and --CF.sub.2 --CF(CF.sub.3)--O--, and a functional group selected from the group consisting of COOH, --CH.sub.2 --OH, --CH.sub.2 --COOH, --CH.sub.2 --SO.sub.3 H, --CH.sub.2 --PO.sub.3 H, --(CH.sub.2 --CH.sub.2 --O)--H, and --(CH.sub.2 --CH(CH.sub.3)--O--)--H.
摘要:
A process is disclosed of preparing a high chloride {111} tabular grain emulsion. Tabular grains are formed having {111} major faces, containing at least 50 mole percent chloride and less than 5 mole percent iodide, based on silver, and accounting for at least 50 percent of total grain projected area by introducing silver ion into a gelatino-peptizer dispersing medium containing a stoichiometric excess of chloride ions with respect to silver ions and an iodo-substituted 8-hydroxyquinoline, which acts as a grain growth modifier.

Photographic elements having oxonol dyes of the formula: ##STR1## R.sup.1 and R.sup.2 each independently represent alkyl of from 1 to 5 carbon atoms are disclosed. The dyes are particularly useful as filter dyes in the form of solid particle microcrystalline dispersions.
摘要:
A double coated radiographic element is disclosed comprised of a dye coated between an emulsion layer and a support to reduce crossover to less than 10 percent. The dye is present in the form of microcrystalline particles, yet is capable of being decolorized in less than 90 seconds during processing.
