Abstract
Abstract A light-sensitive silver halide photographic material comprising a support bearing at least one light-sensitive silver halide emulsion layer comprising from 10- 8 to 10- 5 mole of metal ion per mole of silver halide present, and silver halide grains containing 80 to 99 mole% of silver chloride and having a silver bromide-rich phase.
