摘要： A radiation-sensitive emulsion particularly adapted to forming a direct-positive image, comprised of a dispersing medium and silver halide grains, and a direct-positive photographic element containing the same are disclosed. The emulsion is characterized by
a first, core-shell silver halide grain population having a coefficient of variation of less than 20%, and a second silver halide grain population capable of Internally trapping photolytically generated electrons and incapable of forming a surface latent image within the direct-positive exposure latitude of the first grain population, said second grain population have an average diameter less than 70% that of said first grain population, and said first and second silver halide grain populations being present in a weight ratio range of from 5:1 to 1:5.

摘要： Photographic elements particularly adapted for forming direct positive images, comprised of a support and, coated on said support, a plurality of silver halide emulsion layers, the emulsion layers are characterized by
a first, radiation sensitive emulsion layer containing core-shell silver halide grain population having a coefficient of variation of less than 20%, and a second silver halide emulsion layer substantially incapable of forming a surface latent image within the direct positive exposure latitude of the first emulsion layer and containing a second grain population capable of internally trapping photolytically generated electrons, said second grain population having an average diameter less than 70% that of said first grain population, and said first and second silver halide grain populations being present in a weight ratio of from 5:1 to 1:5.
