PURPOSE:To obtain the photosensitive material with the high sensitivity and the excellent stability by incorporating an inner latent image type silver halide particle specified in a ratio of the thickness to the length of the particle in the title material. CONSTITUTION:The inner latent image type silver halide particle which is composed of an outermost shell contg. silver chloride and has the ratio of the thickness to the length of the particle of more than (1:8), is incorporated in at least one layer of silver halide emulsion layers. The ratio of the thickness to the length of the inner latent image type silver halide particle is preferable more than (1:8) and less than (1:150), further preferably more than (1:20) and less than (1:150). Thus, the photosensitive material which has the high sensitivity, the less change of the sensitivity against a development processing time and the small min. optical density and the excellent development processing stability, is obtd. |
