Abstract (en)
[origin: EP1030216A2] Disclosed is an internal latent image-type direct positive silver halide photographic emulsion having a core/shell structure comprising a chemically sensitized core and a chemically sensitized shell, wherein a compound having an adsorbing group to silver halide and a reducing group, or a precursor thereof is contained together with a gold sensitizer and a compound having C=X bond, P=X bond or R-XO2X bond (wherein X represents sulfur, selenium or tellurium and R represents an aliphatic hydrocarbon group, an aryl group or a heterocyclic group) at the chemical sensitization of the core and/or shell. A color diffusion transfer light-sensitive material using the emulsion.
