Abstract: The present invention provides a photographic element comprises a support, at least one hydrophilic light-sensitive layer, and a light-insensitive layer containing a binder and polymer matte particles having the formula:(A).sub.x (B).sub.y (C).sub.z (I)where A is a monofunctional ethylenically unsaturated monomer which forms a homopolymer with a Tg less than 20.degree. C., B is a monofunctional ethylenically unsaturated monomer which forms a homopolymer with a Tg greater than 60.degree. C., C is a monomer with two or more ethylenically unsaturated groups, x is about 10 to 95 mole %, y is less than 85 mole %, and z is about 5 to 90 mole %.

Abstract: Medical diagnostic radiographic elements capable of being processed in less than 45 seconds are disclosed that exhibit reduced gloss non-uniformities, Gloss non-uniformity reduction is attributable to the presence of a hydrophilic colloid layer overlying the imaging layer unit containing radiation-sensitive nontabular silver halide grains accounting for from 0.5 to less than 10 percent of monolayer coverage and having a mean equivalent circular diameter ranging from greater than the thickness of the overlying hydrophilic colloid layer up to 1.6 times the thickness of the overlying hydrophilic colloid layer.

Abstract: A mammographic medical diagnostic radiographic element is disclosed that produces sharp images and is capable of being processed in less than 60 seconds. Each of imaging and antihalation fully forehardened hydrophilic colloid layer units are coated on the opposite sides of a transparent film support at a hydrophilic colloid coating coverage of less than 55 mg/dm.sup.2. The radiation-sensitive silver halide grains contained in the imaging layer unit are provided by a tabular grain emulsion coated at a coverage capable of providing a maximum density on processing of greater than 3.6. To provide a mid-scale contrast of greater than 3.0 and a lower scale contrast of greater than 2.2, the radiation-sensitive grains (a) exhibit an equivalent circular diameter coefficient of variation grain of less than 15 percent and (b) contain rhodium in a normalized molar concentration of less than 1.times.10.sup.-6 based on silver.

Abstract: A photographic element comprising a support, at least one hydrophilic light-sensitive layer, and a light-insensitive layer containing a binder and solid, nonporous polymer matte particle having the formula:(A).sub.x (B).sub.ywhere A is a monofunctional ethylenically unsaturated monomer, B is a polyfunctional ethylenically unsaturated monomer, x is from 0 to 55 mole %, and y is about 45 to 100 mole %.

Abstract: A radiation-sensitive film for reproducing digitally stored medical diagnostic images through a series of laterally offset exposures by a controlled radiation source followed byprocessing in 90 seconds or less including development, fixing and drying is disclosed. 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 is provided in which silver bromochloride grains provided (a) containing 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 is at least one spectral sensitizing dye having an absorption half peak bandwidth in the spectral region of exposure by the controlled exposure source.
