Title: Photosensitive material
Inventor: YAMAMOTO SOICHIRO
IPC: G03F7/06
Filed: 1986-11-11
Abstract: PURPOSE:To permit improvement in gradation reproducibility and formation of a sharp image by specifying the fluctuation coefft. rho/r [rho is a standard deviation of particle sizes and (r) is an average particle size] of the size distribution of silver halide particles to a specific range. CONSTITUTION:The fluctuation coefft. rho/r [rho is the standard distribution of the particle size and (r) is the average particle size] of the size distribution of the silver halide particles is specified to 15-50%. This photosensitive material is formed by utilizing the silver halide particles as a photosensitive body and is developed generally by dry process processing such as heating; in succession thereof, the polymn. process is accelerated or suppressed imagewise. The dissolution of the silver halide particles more hardly arises than in the case of developing the material in a liquid such as the conventional photographic sensitive materials. The sensitivity is determined by the sizes of the silver halide particles. As a result, the gradation expression of the image obtd. is rich if the size distribution of the silver halide particles widened is. The sharp image having the gentle and good gradation reproducibility is thereby obtd.
