The silver halide photographic light-sensitive material of claim 1 wherein R.sub.1, R.sub.2 and R.sub.3 of the general formula (I) are hydrogen atoms and R.sub.3 is a substituted or unsubstituted alkyl or aryl group having up to 13 carbon atoms, such alkyl or aryl being bonded directly or through a divalent linkage group to the aromatic nucleus.
- 7. The silver halide photographic light-sensitive material of claim 1 wherein R.sub.1 and R.sub.4 of the general formula (I) are hydrogen atoms and R.sub.2 is a substituted or unsubstituted alkyl or aryl group having up to 13 carbon atoms, such alkyl or aryl being bonded directly or through a divalent linkage group to the aromatic nucleus and R.sub.3 is a substituent group.
- 8. The silver halide photographic light-sensitive material of claim 1 wherein R.sub.1 and R.sub.4 of the general formula (I) are hydrogen atoms and R.sub.2 is a substituted group and R.sub.3 is a substituted or unsubstituted alkyl or aryl group having up to 13 carbon atoms, such alkyl or aryl being bonded directly or through a divalent linkage group to the aromatic nucleus.
- 9. The silver halide photographic light-sensitive material of claim 1 wherein R.sub.1, R.sub.3 and R.sub.4 of the general formula (I) are hydrogen atoms and R.sub.2 is a substituted or unsubstituted alkyl or aryl group having up to 13 carbon atoms, such alkyl or aryl being bonded directly or through a divalent linkage group to the aromatic nucleus.
- 10. The silver halide photographic light-sensitive material of claim 1 wherein R.sub.1 and R.sub.4 of the general formula (I) are hydrogen atoms and R.sub.2 and R.sub.3 are substituted or unsubstituted alkyl or aryl group having up to 13 carbon atoms, such alkyl or aryl being bonded directly or through a divalent linkage group to the aromatic nucleus.
- 11. The silver halide photographic light-sensitive material of claim 1 wherein the light-sensitive silver halide emulsion is a surface latent type emulsion.
- 12. The silver halide photographic light-sensitive material of claim 1 wherein the silver halide of the light-sensitive silver halide material comprises silver bromoiodide.
- 13. The silver halide photographic light-sensitive material of claim 12 wherein the iodide content ranges from about 2 to about 30 mole %.
- 14. The silver halide photographic light-sensitive material of claim 1 wherein said light-insensitive silver halide comprises at least one compound selected from the group consisting of silver chloride, silver bromochloride, silver bromide and silver bromoiodide.
- 15. The silver halide photographic light-sensitive material of claim 1 wherein the mean grain size of the light-insensitive silver halide comprises 0.05 to about 0.4 micron.
- 16. The silver halide photographic light-sensitive material of claim 1 wherein the light-insensitive silver halide emulsion is not chemically sensitized.
- 17. The silver halide photographic light-sensitive material of claim 1 wherein the silver halide grains are monodispersed.
- 18. A processing method of a silver halide photographic light-sensitive material comprising treating an imagewise exposed silver halide photographic sensitive material of claim 1 with a developing solution.
