    摘要: A silver halide emulsion which comprises silver halide grains dispersed in a hydrophilic colloid mixture comprising from 5% to 25% by weight of dextran, from 20% to 40% by weight of hydrogenated poly-saccharide having an average molecular weight equal to or lower than 10,000, and from 40% to 60% by weight of gelatin. A fore-hardened photographic material comprising such an emulsion and the use of such an emulsion in a photographic material increases the sensitometry and mechanical resistance of such a photographic material.
