    摘要: A silver halide imaging element is disclosed that is capable of providing a sharp image with silver halide grains still present following imagewise exposure and development. This is achieved by choosing a dispersing medium for the silver halide grains comprised of an organic vehicle and, dispersed therein, titanium dioxide particles having an average size of less than 0.1 micrometer accounting for at least 10 percent by weight of the dispersing medium. The elements are useful for optical printing or scan image retrieval without fixing. The elements can be used for providing black-and-white photographic images, radiographic images or dye images.
