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.
