摘要： The invention provides a light sensitive photographic silver halide emulsion layer having associated therewith a magenta coupler having formula I: ##STR1## wherein: R represents a ballasted monosubstituted amino group which enables the coupler to form, upon development with 4-amino-3-methyl-N-ethyl-N-(2-hydroxyethyl)aniline sulfate developing agent, a magenta dye having a wavelength of maximum absorbance of 545 nm or greater; andX represents hydrogen or a coupling-off group. The resulting dye has an improved spectral absorption curve.

摘要： A multicolor negative photographic element comprises a support bearing a blue light-sensitive silver halide emulsion first layer and a green light-sensitized silver halide emulsion second layer wherein said second layer contains a dye sensitized to green light and wherein said first layer has associated therewith a hue correction coupler which upon coupling with oxidized developer produces a dye having a maximum absorbance in the range of 460 to 510 nm. so that the element has a D480/D440 density ratio which is greater than that exhibited by the element without the hue correction coupler. The invention also encompasses a blue sensitive silver halide emulsion layer associated with the hue correction coupler and a method of forming an image in the photographic element of the invention.
