Abstract

PURPOSE:To obtain a soft gradient stably to an exposure wavelength region by providing at least one layer of silver halide emulsion layers contg. a mixture of >=2 silver halide emulsions having different average grain sizes on backing. CONSTITUTION:The respective silver halide emulsions of different average grain sizes contg. a mixture of at least two silver halide emulsions having different average grain sizes are added with sensitizing dyes in such a way that the amt. of the sensitizing dyes per unit surface area of the silver halide particles is larger in order of larger average grain sizes, after which the silver halide emulsions of the different average grain sizes are mixed therewith. Such silver halide emulsions are coated on backing of polyethylene terephthalate film, glass, baryta paper or the like, if necessary, via an undercoating layer, an anti-halation layer, and a filter layer, whereby the silver halide photographic material is obtained.
