| 摘要 |
Photosensitive elements particularly suitable for use in diffusion transfer photographic film units which include a plurality of essential layers including at least one photosensitive silver halide layer having associated therewith a dye image-forming material which is diffusible during processing as a function of the point-to-point degree of silver halide exposure to actinic radiation and a layer adapted to receive image-forming material diffusing thereto and means for applying an aqueous processing composition. The silver halide layer comprises gelatin and inert particles which are compatible with gelatin, non-swelling in alkali and substantially non-film forming, wherein said inert particles are equal to or less than the silver halide grains in average diameter and wherein the silver halide grains are 2.5 microns or less in average diameter. Preferably, the inert particles are derived from a polymeric latex. In a particularly preferred embodiment, the photosensitive silver halide layer comprises a first and second photosensitive silver halide layer in contiguous relationship. |
