Abstract
The invention provides a cyan color producing silver halide emulsion layer or a magenta color producing silver halide emulsion layer wherein said at least one layer has an exposure range of at least 0.6 log E from the point where the instantaneous contrast is 1.0 and wherein the instantaneous contrast of said layer increases as a function of increasing exposure over at least 70 percent of said exposure range.
Claims34
A method of forming a photographic image comprising providing a multicolor photographic element comprising at least one layer said at least one layer comprising a silver halide emulsion 1ayer containing a cyan dye-forming coupler capable of producing cyan color or a silver halide emulsion 1ayer containing a magenta dye-forming coupler capable of producing a magenta color wherein said at least one layer has an exposure range of at least 0.6 log E from the point where the instantaneous contrast is 1.0 and wherein the instantaneous contrast of said layer increases as a function of increasing exposure over at least 70 percent of said exposure range, exposing said element to actinic radiation to form a latent image, and developing said latent image with a color developing agent to yield a color image.
