The present invention relates to a new silver halide tabular grain emulsion, wherein said silver halide emulsion comprises tabular grains having average thickness lower than 0.15 &#x3bc;m, an average diameter of at least 1.20 &#x3bc;m and an average aspect ratio of at least 8:1, and showing a coefficient of diameter variation COVd within the range of from 31% to 44% and a coefficient of thickness variation COVt lower than 25%.

Silver halide tabular grain emulsion

A silver halide emulsion which comprises silver halide tabular grains showing an average thickness lower than 0.15 &#x3bc;m, an average diameter of at least 1.20 &#x3bc;m and an average aspect ratio of at least 8:1 dispersed in a hydrophilic colloid mixture comprising from 10% to 30% by weight of dextran, from 20% to 40% by weight of a hydrogenated polysaccharide having an average molecular weight equal to or lower than 10,000, and from 40% to 60% by weight of gelatin and photographic element comprising it.
