Abstract

PURPOSE:To improve the color reproducibility of the titled material, by incorporating at least one layer of a core/shell type inner latent image type silver halide particle, and a specified coupler in at least one layer of a silver halide emulsion layer, and curing the silver halide emulsion layer with a hardening agent composed of a specified compd. CONSTITUTION:At least one layer of the silver halide emulsion layer composed of the core/shell type inner latent image type silver halide particle composed of the outermost shell layer contg. silver chloride and the coupler shown by formula I. And, the silver halide emulsion layer is cured with at least one of the hardening agent selected from the compds. shown by formulas II and III. In the formula, Z is a nonmetal atomic group necessary for forming a nitrogen contg. heterocyclic ring, X and R are each hydrogen atom or a substituting group, R21, R22, R31 and R32 are each chlorine atom, -OM group (wherein M is hydrogen atom or a monovalent metal atom) is alkyl or alkoxy group, etc., Q and Q' are each -O-, -S- or -NH- group, L is alkylene or arylene group. Thus, the raw shelf-life property of the titled material maintaining a developing property is improved, and the color reproducibility of said material is improved.
