    Abstract: The silver halide grain finishing involves adding a silver halide fine grain emulsion to a high chloride silver halide emulsion during a chemical sensitisation heat cycle. The fine grain emulsion has a photographically useful cpd. adhered to the grain surfaces. The cpd. is a UV absorber, sensitising dye, brightener, antifoggant, luminescent dye, supersensitiser, stabiliser, light absorbing and scattering material, coating aid, plasticiser, lubricant or antistatic agent. Pref. the high chloride emulsion contg. stabiliser were added after 35 minutes at 65[deg]C. (e) 0.03 mg/mole of K Ir(IV) hexachloride was added as an aq. soln. after 43 mins. at 65[deg]C. (f) a fine grain AgBr (0.05-0.1mu ) emulsion (1 mol% of total Ag) carrying 10-3mg/mole of the mercaptan antifoggant after 45 mins. at 65[deg]C, and (g) after 65 mins. at 65[deg]C the emulsion was cooled back to 40[deg]C. The fine grain AgBr emulsion was mixed with the mercaptan cpd. and held at 40[deg]C prior to its addn. to the AgCl emulsion. The prepd. emulsion was incorporated in a multicolour; multilayer photographic material which was then exposed and processed. The emulsion layer had the following characteristics for the fresh emulsion speed (S) sensitivity = 1.22 (1.23), shoulder density (SD) = 1.53 (1.62), toe density (7D) = 0.20 (0.19), and Dmin = 0.103 (0.104), following incubation at 120[deg]F for 28 days ~DS = +0.02(+0.22), ~D2S = -0.004(-0.08), ~DTD = 0.00 (+0.08) ~DDmin = + 0.017(+0.070).

    Abstract: A photothermographic recording material comprising a photo-addressable thermally developable element coatable from aqueous media comprising a substantially light-insensitive organic silver salt, photosensitive silver halide in catalytic association with the substantially light-insensitive organic silver salt and a reducing agent in thermal working relationship with the substantially light-insensitive organic silver salt and a binder, characterized in that the binder comprises a water-soluble polymer, a water-dispersible polymer or a mixture of a water-soluble polymer and a water-dispersible polymer and particles of the photosensitive silver halide are non-aggregating in the photo-addressable thermally developable element and are uniformly distributed over and between particles of the substantially light-insensitive organic silver salt, at least 80% by number of the particles having a diameter, determined by transmission electron microscopy, of

    Abstract: An ultra-high contrast silver halide photographic material which is suitable for daylight use and which has at least one silver halide emulsion layer on a support, wherein the emulsion layer contains cubic silver halide grains having a mean grain size of 0.15 um or less and containing silver chloride in an amount of 99 mol% or more. The material can contain a rhodium salt or an organic desensitizer for lowering the sensitivity while maintaining the high contrast photographic property thereof.

    Abstract: A photograhic image is formed with silver halide emulsions by using optically unsensitized light sensitive (coarse) silver halide grains. Optically (or spectrally) sensitized fine grains (or crystals or particles), - espe­cially light insensitive or Lippmann silver halide grains-, can be reactively associated with optically (or spectrally) unsensitized light sensitive (coarse) silver halide grains to get a combination of Spectrally Sensi­tized Fine Grains with Spectrally Unsensitized Light Sen­sitive or Coarse Grains, - especially Tabular Grains -, which can be imagewise exposed (to the light absorbed by the dye sensitizer adsorbed on the surface of such fine grains) and developed with substantially the same sensi­tivity of the light sensitive optically sensitized (coarse) silver halide grains.
