PURPOSE:To obtain the titled material having a large inter-image effect, without imparing an another photographic characteristics by incorporating one kind of a specific compd. to an emulsion layer contg. a specific silver halide particle and/or a nonphotosensitive layer. CONSTITUTION:The silver halide emulsion layer contain a monodispersive silver halide particle, and the silver halide particle is the core/shell type silver halide particle which contains a larger amount of silver iodide in a core part than that of a shell part in said particle. And, at least one kind of the compd. shown by the formula is incorporated in the emulsion layer contg. silver halide particle and/or the non-photosensitive layer. In the formula, R is a straight or a branched alkylene or alkenylene group, etc., Z is hydrogen atom or a polar substituent group, Y is -S-, etc., X is hydrogen atom, an alkali metal atom or a group capable of cleaving at an alkaline condition, (n) is 0 or 1. |
