 | Gold halides are compounds of gold with the halogens. |
| A ratio of a gold sensitizer to a sulfur or selenium sensitizer is preferably such that the ratio of the number of gold atoms to that of sulfur atoms or selenium atoms forming silver sulfide or silver selenide ranges from 1/2 to 1/200. |
| In a preferred embodiment of the present invention, silver halide grains are subjected to reduction sensitization, and further subjected to sulfur sensitization or selenium sensitization in combination with gold sensitization in the presence of a nitrogen-containing heterocyclic compound capable of forming a complex with silver. |
