Abstract
A silver halide photographic material is disclosed. The material has at least one silver halide emulsion layer on a support, said silver halide emulsion layer containing a coupler which forms a mobile dye by coupling reaction with the oxidized product of a color developing agent, and said silver halide emulsion layer having in association therewith a non-light sensitive layer containing substantially non-light sensitive fine silver halide grains.
Claims25
A silver halide photographic material having formed on a support at least one unit structure consisting of two or more silver halide emulsion layers which are sensitive to light of substantially the same color but which have different sensitivities, one of said silver halide emulsion layers having a highest sensitivity containing a coupler which forms a mobile dye by coupling reaction with an oxidized product of a color developing agent and said silver halide emulsion layer with said highest sensitivity having in association therewith a non-light-sensitive layer containing substantially non-light-sensitive fine silver halide grains, said non-light-sensitive layer adjoining said silver halide emulsion layer with said highest sensitivity, said silver halide emulsion layer with said highest sensitivity being positioned furthest from said support in said unit.
A method of forming color negative images by imagewise exposing a silver halide phtographic material and then processing the exposed material with a color developer, said material having formed on a support at least one unit structure comprising two silver halide emulsion layers which are sensitive to light of substantially the same color but which have different sensitivites, one of said silver halide emulsion layers having a highest sensitivity containing a coupler which forms a mobile dye by coupling reaction with an oxidized product of a color developing agent, and said silver halide emulsion layer with the highest sensitivity having in association therewith a non-light-sensitive layer containing substantially non-light-sensitive fine silver halide grains, said non-light-sensitive layer being positioned adjacent to said silver halide emulsion layer having the highest sensitivity in the unit and in a place furthest from said support.
A silver halide photographic material having formed on a support at least one unit structure consisting of two or more silver halide emulsion layers which are sensitive to light of substantially the same color but which have different sensitivities, one of said silver halide emulsion layers having a highest sensitivity containing a coupler which forms a mobile dye by coupling reaction with an oxidized product of a color developing agent and said silver halide emulsion layer with said highest sensitivity having in association therewith a non-light-sensitive layer containing substantially non-light-sensitive fine silver halide grains and being positioned farther away from the support in said unit, said non-light-sensitive layer adjoining said silver halide emulsion layer with said highest sensitivity, said non-light-sensitive layer being positioned furthest from said support in said unit.
