Color photographic material comprising silver halide light-sensitive and non light-sensitive layers |
摘要 |
A silver halide photographic light-sensitive material comprising a support having thereon at least two light-sensitive silver halide emulsion layers which are sensitive to light of substantially the same spectral region and a relatively light-insensitive layer containing silver halide, zinc oxide or titanium oxide positioned between the two light-sensitive silver halide emulsion layers and at least one of the two light-sensitive silver halide emulsion layers containing a compound represented by the following general formula (I): A-B (I) wherein A represents a residue of a compound capable of coupling with the oxidation product of an aromatic primary amine developing agent by removal of a hydrogen atom from the active position of the compound, and B represents a group which is released on coupling and exhibits a fogging function in a developing solution. The silver halide photographic light-sensitive material containing the compound represented by the general formula (I) has improved granularity as well as has high sensitivity.
