Abstract
An imaging element is disclosed comprised of a support and, coated on the support, at least one radiation-sensitive emulsion layer containing (a) radiation-sensitive silver halide grains and (b) an aqueous processing solution permeable vehicle, wherein the radiation-sensitive emulsion layer additionally contains (c) from 0.1 to 10 mg/dm.sup.2 of magnetic particles having a major axis less than 1 .mu.m and, (d) based on the weight of the magnetic particles, from 10 to 200 percent of an amphipathic dispersant for the magnetic particles having a hydrophilic/lipophilic balance number of at least 8.
