Abstract
Forehardened photographic elements, particularly radiographic elements, intended to produce silver images are disclosed including among hydrophilic colloid layers at least one emulsion layer containing thin tabular silver halide grains. When developed in less than 1 minute to produce a viewable silver image, these photographic elements exhibit increased covering power.
