ABSTRACT:
A dual coated radiographic element is disclosed including at least one radiation-sensitive emulsion comprised of silver halide grains containing greater than 50 mole percent bromide and less than 4 mole percent iodide, based on silver, with greater than 50 percent of total grain projected area being accounted for by tabular grains having {111} major faces, a spectral sensitizing dye adsorbed to the surfaces of the silver halide grains, and hydrophilic colloid vehicle acting as a peptizer and a binder for the silver halide grains. At least the portion of the vehicle acting as a peptizer is a hydrophilic colloid derived from a water dispersible cationic starch.
