Abstract: A direct positive photographic light-sensitive material is described, comprising a support and at least one internal latent image type silver halide emulsion layer containing core/shell type silver halide grains which are composed of a silver halide core subjected to at least one of doping with metal ions and chemical sensitization, and a silver halide shell covering at least sensitivity sites of said core, and a binder, wherein said core/shell type silver halide grains consist of two or more kinds of grains each having a different average grain size, and the core of the core/shell type silver halide grains having a larger average grain size is doped with a larger amount of lead ions, cadmium ions, or Group VIII metal ions.

Abstract: A previously unfogged internal latent image-type direct positive silver halide emulsion and a photographic material incorporating such emulsion are described, wherein the emulsion contains at least one sensitizing dye represented by formula (I): ##STR1## wherein one of R.sup.1 and R.sup.2 represents a sulfoalkyl group and the other thereof represents an unsubstituted or substituted alkyl group, an unsubstituted or substituted aryl group, or a pyridyl group; X represents a sulfur atom or an oxygen atom; Y represents a sulfur atom, an oxygen atom, or ##STR2## wherein R represents a lower alkyl group or --CH.sub.2).sub.n.sbsb.1 O--CH.sub.2).sub.n.sbsb.2 OH, wherein n.sub.1 and n.sub.2 each represents an integer of 1 to 4; and W represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, or an unsubstituted or substituted phenyl group.
