Abstract
A photographic recording material comprising a support bearing at least one photographic layer comprising a sensitized high aspect ratio tabular grain silver halide emulsion and at least one spatially fixed dye layer spatially positioned between said silver halide layer and the upper surface of said recording material, said dye layer comprises a spatially fixed dye that absorbs light in the region of the spectrum to which the silver halide is sensitized.
Claims11
A color negative photographic recording material comprising a support bearing at least one photographic layer comprising a sensitized high aspect ratio tabular grain silver halide emulsion having an average aspect ratio of greater than 10 and at least one dye layer positioned between said silver halide layer and the upper surface of said recording material, said dye layer comprising a spatially fixed dye that absorbs light in the region of the spectrum to which the silver halide is sensitized, wherein said photographic material comprises a dye forming DIR coupler compound and colored masking couplers.
A process of forming a color negative image comprising providing a color negative recording material comprising a support bearing at least one photographic layer comprising a sensitized high aspect ratio tabular grain silver halide emulsion having an average aspect ratio of greater than 10 and at least one dye layer positioned between said silver halide layer and the upper surface of said recording material, said dye layer comprising a spatially fixed dye that absorbs light in the region of the spectrum to which the silver halide is sensitized, exposing said color negative recording material to actinic radiation, contacting said color negative recording material with developing agent to reduce developable silver halide and oxidize the color developing agent, the oxidized color developing agent in turn reacts with coupler in said dye layer to yield dye, then contacting said color negative recording material with a bleach, a fixer or bleach-fixer, washing and drying to yield a color negative.
