SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL

摘要

PURPOSE:To obtain a high image having high sensitivity, high contrast and max. density by incorporating a surface latent image type silver halide emulsion and internal fogging type silver halide emulsion of which silver halide particles have a (110) crystal face. CONSTITUTION:This photosensitive material has the silver halide compsn. substantially consisting of silver bromide or silver iodobromide. The surface latent image type silver halide emulsion is preferably the emulsion having the sensitivity of the emulsion relatively higher than the sensitivity of the internal fogging type silver halide emulsion having fogging nuclei in the inside in ordinary development and has preferably the sensitivity of >=10 times the sensitivity of the emulsion of the internal fogging type. The preferable content of the silver halide of the surface latent image type is in a 0.1-30mol% in the case of silver iodide. The ratio of the particles of the (110) face in the emulsion of the internal fogging type is >=30%. The photosensitive material which has the high sensitivity, high contrast and high max. density and has the excellent granularity to provide the low fogging image is thus obtd.
