摘要： A diagnostic photographic element is disclosed containing reduced surface glare following rapid-access processing. The photographic elements contain silver halide emulsion imaging units and overlying layer units that contain to reduce surface glare a tabular grain silver halide emulsion in which the tabular grains have an average diameter greater than 1.5 .mu.m and an average tabularity of greater than 25.

摘要： A double coated radiographic element is disclosed which exhibits a crossover of less than 5 percent and which is provided with a first silver halide emulsion layer unit on one side of its transparent film support that exhibits an average contrast of less than 2.0 and a second silver halide emulsion layer unit on the opposite side of the silm support that exhibits an average contrast of at least 2.5.
