Abstract
PURPOSE:To suppress the reduction of the intrinsic sensitivity of an emulsion layer due to a dye and to increase the photosensitivity by highly controlling the emulsion layer so that chemical sensitizing nuclei (latent image) are formed only on the (100) faces of silver halide 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 (100) faces of normal crystal particles are allowed to account for >=60% of the surfaces of the used particles. The emulsion layer is controlled so that a latent image is preferentially formed on the (100) faces of normal crystal particles corresponding to >=60% of the number of the normal crystal particles. 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.
