Silver halide photographic light-sensitive materials
摘要:
A silver halide photographic light-sensitive material comprising a support having coated thereon at least one silver halide emulsion layer and a surface protecting layer, said silver halide photographic light-sensitive material comprising photosensitive silver halide grains and internally fogged silver halide grains, said intemally fogged silver halide grains having adsorbed thereon at least one compound represented by the formula (I):
wherein X represents -0-, -NH- or -S-, R 1 , R 2 , R 3 and R 4 represent hydrogen atom or a substituent, and at least one of R,, R 2 , R, and R. is substituted or unsubstituted alkyl or aryl group having up to 13 carbon atoms, which is bonded directly or through a divalent linkage group, to the aromatic nucleus.
