Abstract

PURPOSE:To suppress the reduction of the intrinsic sensitivity of an emulsion layer due to a dye and to increase the spectral sensitivity by incorporating a spectral sensitizing dye which is selectively adsorbed on (100) faces rather than (111) faces into the emulsion layer so that a latent image is preferentially formed on faces other than the (111) faces of specified normal crystal particles. CONSTITUTION:Silver halide particles which are practically normal crystals consisting essentially of (111) and (100) faces are used as >=50% of the total projection area of all of silver halide particles in a silver halide emulsion layer and the (111) faces of normal crystal particles are allowed to account for >=40% of the surfaces of the used particles. In the emulsion layer, >=60% of the number of the normal crystal particles have been spectrally sensitized with a sensitizing dye which is selectively adsorbed on (100) faces rather than (111) faces so that a latent image is preferentially formed on faces other than the (111) faces. Thus, a silver halide sensitive material contg. a silver halide emulsion suppressing the reduction of the intrinsic sensitivity due to a dye and having high sensitivity can be obtd.
