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.

Color negative element having improved blue record printer compatibility

The invention provides a multicolor negative photographic element which contains a layer containing a yellow or orange-yellow azoaniline dye of structure I ##STR1## wherein: R.sub.1 is an alkyl group or a phenyl group;

Photographic element containing certain azoaniline dyes

A color photographic silver halide negative working duplicating element comprising a support having thereon at least one red-sensitive photographic silver halide emulsion layer comprising at least one cyan image-dye forming coupler; at least one green-sensitive photographic silver halide emulsion layer comprising at least one magenta image-dye forming coupler; and, at least one blue-sensitive photographic silver halide emulsion layer comprising at least one yellow image-dye forming coupler, provides improved images when (a) at least one of the layers comprises a unit of at least two layers including a first layer and a second layer, the first layer having a higher photosensitivity than the second layers and being farther from the support than the second layers; (b) the first layers contain an image-dye forming coupler in an amount insufficient to react with all the oxidized developer formed during development after maximum exposure; (c) the image-dye forming couplers of the first layers being in a dispersion having a mean particle size of less than 0.14 micron; and, (d) the silver halide grains of the first layers having a mean grain volume less than 0.015 cubic micron. Such a photographic element is especially useful in motion picture film duplication providing reduction in granularity of the image.
