PURPOSE:To improve the sharpness of an obtd. photographic image by specifying the film thickness of the total hydrophilic colloid layers contd. in the photsensitive material, and by using a means capable of forming an unsharpe positive image. CONSTITUTION:The total thickness of the total hydrophilic colloid layers existing in the side of an emulsion mounted on a supporting body is <=18mum, and the means capable of forming the unsharpe image is mounted on at least one layer of the hydrophilic colloid layers. The film thickness of the colloid layer means a dried film thickness measured at 23 deg.C, under a humidity of 55%. The film thickness of each layers is obtd., by applying magnified photography to the section of a dried sample by means of an electron microscope. Thus, the color photosensitive material with remarkably improved sharpness, is improved the modulation transfer function of the photosensitive material at a high frequency domain so as to endure to extend especially the photographic image with a high magnification. |
