Abstract:
A multilayer light-sensitive silver halide photographic negative image type material comprising on at least one side of a support a multilayer composition of at least two layers of negative image type silver halide emulsions adjacent to each other, wherein the emulsion layer more close to the said support comprises at least one emulsion having tabular emulsion crystals selected from the group consisting of silver chloride, silver chlorobromide, silver chloroiodide and silver chlorobromoiodide having a {111} crystal habit and silver chloride, silver chlorobromide, silver chloroiodide and silver chlorobromoiodide having a {100} crystal habit, wherein the adjacent layer(s) farther from the said support comprise(s) at least one emulsion having essentially cubic emulsion crystals selected from the group consisting of a silver chloride, silver chlorobromide and silver bromide,wherein the said tabular silver chloride, silver chlorpbromide, silver chloroiodide or silver chlorobromoiodide emulsion crystals having {111} or {100} major faces have at least 50 mole % of chloride and wherein the essentially cubic grains are less sensitive than the tabular grains.
