SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL WITH WHICH IMAGE QUALITY AND GRADATION ARE SELECTABLE SO AS TO MEET PURPOSE OF PHOTOGRAPHING AND ITS IMAGE FORMING METHOD

摘要

PURPOSE: To obtain the silver halide photographic sensitive material for X-rays with which the characteristics meeting the purposes of photographing can be obtd. by one sheet of film and the images having good graininess can be obtd. with a high sensitivity and high sharpness by combination with sensitizing paper. ;CONSTITUTION: The max. density of the images formed from the respective emulsion surfaces provided on both surfaces of the transparent base of this silver halide photographic sensitive material varies. The max. density of the surface having the higher max. density is ≥1.80. The density of the surface which is lower in the max. density is ≤+0.20 fogging when the photosensitive material is so exposed that the density of the images from both surfaces attains +1.10 fogging. In addition, the sensitivity of the surface having the higher max. density is lower than the sensitivity of the rear surface.;COPYRIGHT: (C)1993,JPO&Japio
