-1- IMAGE-TRANSFER REVERSAL EMULSIONS AND ELEMENTS WITH INCORPORATED QUINONES Abstract of the Disclosure Direct-positive photographic emulsions and elements which include internal-image silver halide grains, a nucleating amount of a hydrazine compound and a redox dye releaser are improved by the incor- poration of a nucleation-promoting amount of a qui- none oxidizing agent. Diffusion transfer images made from elements using these emulsions exhibit improved image discrimination and improved maximum density.
