摘要： A radiation-sensitive silver halide film for reproducing digitally stored medical diagnostic images through a series of laterally offset exposures by a controlled radiation source followed by processing in 90 seconds or less, including development, fixing and drying. The film exhibits an average contrast in the range of from 1.5 to 2.0, measured over a density above fog of from 0.25 to 2.0. An emulsion layer is provided in which silver bromochloride grains (a) comprised of at least 10 mole percent bromide, based on silver, (b) having a mean equivalent circular diameter of less than 0.40 .mu.m, (c) exhibiting an average aspect ratio of less than 1.3, and (d) coated at a silver coverage of less than 40 mg/dm.sup.2. Adsorbed to the surfaces of the silver bromochloride grains at least one spectral sensitizing dye having an absorption half peak bandwidth in the spectral region of exposure by the controlled exposure source. The film contains an infrared opacifying dye that is capable of reducing specular transmission through the film before, during and after processing to less than 50 percent, measured at a wavelength within the spectral region of from 850 to 1100 nm. The film contains a magnetic recording layer which provides a positive b* value influence that is more than offset by the negative b* value influence of the silver bromochloride emulsion, allowing magnetic recording layer integration into the film while achieving favorable image tone and minimum density characteristics.

摘要： A photographic element is disclosed comprising a film support, at least one light-sensitive layer, a highly loaded layer which contains more than 30 volume percent of non-film forming particulate material, and upper and lower aqueous coated adjacent layers which are next to the highly loaded layer, the upper adjacent layer being further from the support and the lower adjacent layer being closer to the support relative to the highly loaded layer, each adjacent layer having a film forming binder content of greater than 70 volume percent, and the lower adjacent layer being at least 1.0 micron thick. In accordance with a preferred embodiment of the invention, an imaging element having excellent adhesion characteristics is obtained in combination with excellent magnetic recording characteristics and photographic transparency where the non-film forming particulate material in the highly loaded layer comprises conductive particles, the layer adjacent to the highly loaded layer which is closer to the support comprises a hydrophilic curl control layer, and the layer adjacent to the highly loaded layer which is further from the support or a layer coated thereover comprises an aqueous coated transparent magnetic recording layer, by virtue of the physical flatness, low granularity, and optical density of the element. Also disclosed is a process for simultaneously applying a plurality of coating compositions comprising an aqueous magnetic recording layer coating composition, an antistatic layer aqueous coating composition, and a curl control layer aqueous coating composition, along with other optional conventional gelatin containing aqueous coated layers, onto a support. The placing of the highly filled antistatic layer between two aqueous coated adjacent layers, which in a preferred embodiment of the invention comprise a magnetic recording layer and a curl control layer or two curl control layers, results in excellent adhesion of the coated layers to the support compared to where the antistatic layer is closest to the support. The mechanical properties of a photographic element containing such a highly filled layer is substantially strengthened when the highly filled layer is sandwiched between the two other aqueous coated layers.

摘要： A method of reducing the tendency toward formation of coating non-uniformities in the coating of multilayer photographic elements is disclosed. More particularly, the present invention involves the coating of a non-gelatin coating over a topmost gelatin layer in a photographic element. In one embodiment, a processing-solution-permeable overcoat is simultaneously coated with the emulsion layers onto a photographic substrate, which overcoat becomes water and stain resistant in the photochemically processed product. In the latter embodiment, the overcoat formulation comprises at least one water-dispersible hydrophobic polymer interspersed with a water-soluble polymer.
