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.
