Abstract
A silver halide photographic material having formed on a support two or more layers that have different light sensitivities but have substantially the same color sensitivity is disclosed. In the material, the layer having the highest light sensitivity contains only a compound of formula (I) as a DIR compound and at least one of the remaining layers contains at least one compound of formula (II) as a DIR compound: A--TIME--Z (I) A--Z (II) wherein A is a coupling component capable of reaction with the oxidized product of a color developing agent to release the group TIME--Z (wherein TIME represents a timing group and Z represents a development retarder). The photographic material has improved sharpness and granularity and wide latitude for exposure.
Claims8
A silver halide photographic material comprising a support and two or more light-sensitive layers provided thereon that are sensitive to substantially the same spectral region and have different light sensitivities, wherein the light-sensitive layer having the highest light sensitivity contains only a compound of formula (I) and at least one of the remaining layers contains at least one compound of formula (II):
- A--TIME--Z (I)
- A--Z (II)
- wherein A is a coupling component capable of reaction with the oxidized product of a color developing agent to release the group TIME--Z (wherein TIME represents a timing group and Z represents a development inhibitor).
