发明名称 Photosensitive composition and method for forming a neutral black image
摘要 A photosensitive composition, a photosensitive element employing said composition, and an improved photoimaging method that utilizes the disclosed composition. The improved method concerns a photosensitive element, formed from a photosensitive composition having a substrate layered with silver halide particles in operative association with a polymeric coupler, latently imaged, developed to render the imaged area insoluble, and washed to remove the undeveloped portion of the layer, wherein the improvement comprises addition of selected dispersed pigments to the polymeric coupler so that the optical density of the final image is neutral black.
