PHOTOGRAPHIC SENSITIVE SILVER HALIDE MATERIAL

摘要

PURPOSE:To obtain a sensitive material with high sensitivity and superior grainness while reducing the amount of used silver by forming a silver halide emulsion layer consisting of >=2 kinds of singly dispersed emulsions each having a specified particle size distribution on a support. CONSTITUTION:A silver halide emulsion layer is formed on a support by applying 2-5 kinds of different singly dispersed emulsions each contg. silver halide particles having 0.2-3.0mum average particle size so that the particle size distribution curve of the silver halide particles has 2-5 peaks when the emulsions are mixed, the difference is particle size between the mode of the maximum peak and the mode of the 2nd peak is regulated to >=3mum, and the number of silver halide particles each having a smaller particle size than the middle value of the average particle size of all the constituent particles is made larger than the number of silver halide particles each having a larger particle size than the middle value.
