Silver halide tabular grain emulsion

摘要

A silver halide tabular grain emulsion comprises tabular grains having an average thickness lower than 0.15 mu m, an average diameter of >=1.20 mu m and an average aspect ratio of >=8:1, and showing a coefficient of diameter variation (COVd) within 31-44% and a coefficient of thickness variation (COVt) lower than 25%. An independent claim is included for a silver halide radiographic element, comprising a support and silver halide emulsion layer(s) coated on side(s) of the support, the silver halide emulsion layer comprising a silver halide emulsion as above.
