PURPOSE:To obtain the titled material having a large inter-image effect, without impairing an another photographic characteristics by incorporating a silver halide emulsion having <=0.7mum mean particle size to a photosensitive silver halide emulsion layer, and a kind of a specific compd. to the photosensitive silver halide emulsion layer and/or a nonphotosensitive layer. CONSTITUTION:In the titled material mounted at least one layer of the photosensitive silver halide emulsion layer on a substrate, said layer contains the silver halide emulsion having <=0.7mum mean particle size, and the photosensitive silver halide emulsion layer and/or the non-photosensitive layer contains at least one kind of the compd. shown by formulas I and II. In the formulas, R is a straight or a branched alkylene or alkenylene group, etc., Z and Z' are each a polar substituent, R1 is hydrogen atom, a substd. or an unsubstd. alkyl or aryl group, X is hydrogen atom, an alkaline metal atom, ammonium group or a group capable of cleaving at alkaline condition, (n) is 0 or 1. |
