Abstract
A silver halide photographic light-sensitive material having a silver halide emulsion layer on a support, wherein said silver halide emulsion layer contains a silver halide emulsion in which silver halide tabular grains (fringe-dislocation tabular grains), which have an aspect ratio of 2 to 40 and in which dislocation lines are localized essentially to only fringe portions, occupy 100% to 80% of a total projected area of all grains.

A silver halide photographic light-sensitive material having a silver halide emulsion layer on a support, wherein said silver halide emulsion layer contains a silver halide emulsion in which silver halide tabular grains, which have an aspect ratio of 2 to 40 and in which dislocation lines are localized essentially to only fringe portions, occupy 100% to 80% of a total projected area of all grains, said silver halide tabular grains are formed while iodide ions are rapidly being generated, said iodide ions are rapidly generated from an iodide ion-releasing agent represented by Formula (I) below:
- R--I (I)
- where R represents a monovalent organic residue which releases the iodine atom, I, in the form of ions upon reacting with a base and/or a nucleophilic reagent.
