  • Patent number: 5725999
    Abstract: The invention provides a multilayer color negative photographic element comprising a support, at least one light-sensitive silver halide layer sensitive to each of the blue, green and red regions of the visible spectrum, a magnetic recording layer and a yellow or orange-yellow methine density correction dye of structure I, ##STR1## wherein R.sub.1 is hydrogen or an alkyl group;R.sub.2 is an alkyl group or an aryl group;R.sub.3 is hydrogen, a halogen atom, an alkyl group, an alkoxy group or an aryloxy group;R.sub.4 is hydrogen or an alkyl group;R.sub.5 is hydrogen or an alkyl group;R.sub.6 is hydrogen or an alkyl group;X is oxygen or sulfur;each R.sub.7 is independently a substituent selected from the group consisting of a halogen atom, and alkyl, aryl, alkoxy, aryloxy, carbonamido, sulfonamido, carbamoyl, alkoxycarbonyl, aryloxycarbonyl, acyloxy, acyl, sulfamoyl, sulfonyl, sulfoxyl, alkylthio, arylthio and cyano groups;R.sub.1 and R.sub.2 or R.sub.2 and R.sub.3 may join to form a ring.

  • Patent number: 5723263
    Abstract: 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.
