摘要： 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. The element exhibits improved color balance permitting it to be satisfactorily processed together with conventional photographic elements to produce viewable color images which do not have undesired yellow coloration when some printers are used.

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.
