PURPOSE:To obtain the silver halide photographic sensitive material having the shielding and diffusing effect against a light having a specified wavelength region by composing the titled material of a silver halide particle having a specified range of mean particle size, and by specifying the amount of a coated silver to a prescribed range. CONSTITUTION:The titled material has 0.33-0.54mu, preferably 0.35-0.50mu the mean particle size of silver halide, and 2.3-3.8g/m<2>, preferably, 2.5-3.5g/m<2> the amount of the coated silver. The usable silver halide emulsion may be a polydisperse or a monodisperse, and is preferably the monodisperse. And, when the two or more kinds of emulsions are applied on individual layers respectively, the emulsion layer composed of the silver halide particle having a particle size larger than the mean particle size is preferably mounted on a supporting body at a side far away in distance from said body. Thus, the shielding and diffusing effect of LED having the emission peak of a specified wavelength region of for example, about 950nm is improved, and the titled material capable of detecting a position by LED, is obtd. |
