Abstract

PURPOSE: To simultaneously improve the desensitization of a sensitive silver halide material with high sensitivity due to pressure and the low and high intensity reciprocity law failure characteristics by adding an iridium salt to the surfaces of silver halide particles contg. silver iodide and parts close to the surfaces.
CONSTITUTION: In the preparation of silver halide particles internally contg. 0.01W 7mol% silver iodide and having 0.7W2μm average particle size, by charging a required amount of an aqueous soln. of an iridium salt such as potassium salt of iridium chloride into a reactor immediately before or after the end of the charge of a silver ion soln. and a halide soln. or during or at the end of physical aging, the iridium salt is added to the surface of the silver halide and a part close to the surface by 10-8W10-5mol per one mole silver halide.
