ABSTRACT:
An encased photographic material includes a silver halide light-sensitive material having at least one silver halide emulsion layer on a support. The emulsion layer contains gold- and chalcogen-sensitized silver halide grains and a thiocyanate salt therein. At least 60% of a total projected area of the silver halide grains is occupied by tabular grains having an aspect ratio of 3 or more and having on an average 10 or more dislocation lines per grain. A lightproof container contains the light-sensitive material such that an end portion of the light-sensitive material is positioned outside the lightproof container, and that a gas can pass between an inside and an outside of the lightproof container. A light-transmitting case encases and seals the lightproof container. A hydrogen cyanide gas scavenger is present inside the case.
