摘要： Disclosed is a light-sensitive silver halide multi-layer color photographic material having a light-sensitive silver halide'emulsion layer combined with a non-diffusion coupler on a support, which comprises a light-sensitive silver halide emulsion layer farthest from the support which contains mono-dispersed silver halide grains comprising primarily (100) faces and having an average grain size of 0.2 to 0.8 µm. The light-sensitive silver halide multi-layer color photographic material of the present invention has stable performance against fluctuations in developing processing conditions, has high sensitivity and low fogging.

摘要： A light-sensitive silver halide color photographic material, having at least one light-sensitive silver halide emulsion layer on a support, wherein at least one of said emulsion layer contains light-sensitive silver halide grains having outer surfaces principally comprised of {100} face, and a magenta dye image forming coupler represented by Formula (I) shown below:
wherein Z represents a group of nonmetal atom necessary for formation of a nitrogen-containing hetero ring; said ring formed by Z may have a substituent; X represents a hydrogen atom or a substituent eliminable by the reaction with an oxidant in a color developing agent; and R represents a hydrogen atom or a substituent. which can porovide a light-sensitive silver halide color photographic material having high sensitivity, being low in fogs, and having improved color reproducibility.

摘要： Improved process for preparing silver chlorobromide or silver chloroiodobromide emulsion wherein first silver ion solution and second halide ion solution are mixed by double jet method and mole % of silver bromide, silver chloride and silver iodide are in specified range, characterized in that molar ratio of Br - :Cℓ - :I in second solution is within specified range and further step is included to produce silver halide with control of silver ion concentration by using third solution containing Br- and C ℓ- . Such emulsions have sufficiently narrow grain diameter distribution and silver halide composition distribution, with constant productivity.
