发明名称 Methine yellow density correction dyes for color negative films with magnetic recording layers
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, <IMAGE> I wherein R1 is hydrogen or an alkyl group; R2 is an alkyl group or an aryl group; R3 is hydrogen, a halogen atom, an alkyl group, an alkoxy group or an aryloxy group; R4 is hydrogen or an alkyl group; R5 is hydrogen or an alkyl group; R6 is hydrogen or an alkyl group; X is oxygen or sulfur; each R7 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; R1 and R2 or R2 and R3 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.
