Silver halide photographic emulsion

摘要

A silver halide photographic emulsion comprising grains, wherein 50% or more (numerical ratio) of all the grains are occupied by tabular grains meeting the requirements (i) to (iii): (i) a silver iodobromide or silver iodochlorobromide tabular grain having (111) faces as main planes and having two parallel twin planes; (ii) a thickness of 0.12 mum or less; and (iii) the tabular grains have a grain fringe portion meeting the requirements: (a) the grain fringe portion has a phase of high silver iodide content in either of an upper region and a lower region than a region sandwiched between the two twin planes, and (b) "A", which represents the maximum local silver iodide content (mol %) in the phase of high silver iodide content, satisfies the relationship: A-6.0>=B, wherein "B" represents local silver iodide content (mol %) in an opposite part to the phase of high silver iodide content.
