Abstract
The Silver halide grains in the silver halide emulsion is disclosed, comprising silver halide grains containing three or more kinds of transition metal complexes each having a different electron-releasing time respectively classified into any of Class A (100 seconds or more), Class B (more than 1/10 seconds and less than 100 seconds), Class C (more than 1/1000 seconds and 1/10 seconds or less) and Class D (1/1000 seconds or less).
Claims12
A silver halide emulsion comprising silver halide grains containing three or more kinds of transition metal complexes each having a different electron-releasing time respectively classified into any of Class A (100 seconds or more), Class B (more than 1/10 seconds and less than 100 seconds), Class C (more than 1/1000 seconds and 1/10 seconds or less) and Class D (1/1000 seconds or less), wherein at least one of the three or more kinds of transition metal complexes contained in the silver halide grains is a transition metal complex classified in Class C, and further at least one of the three or more kinds of transition metal complexes contained in the silver halide grains is a transition metal complex classified in Class D.
A silver halide emulsion comprising silver halide grains containing four or more kinds of transition metal complexes, wherein at least three kinds of transition metal complexes among the four or more kinds of transition metal complexes each have a different electron-releasing time respectively classified into any of Class A (100 seconds or more), Class B (more than 1/10 seconds and less than 100 seconds), Class C (more than 1/1000 seconds and 1/10 seconds or less) and Class D (1/1000 seconds or less).
