<p>A photographic element comprising a cyan dye present in the element prior to exposure and development, the dye having the formula: <CHEM> wherein: R1 is an alkoxy group, a phenoxy group or a halogen; R2 is selected from the group consisting of an alkyl group, a phenyl group; a halogen when R1 is an alkoxy or phenoxy group; an alkoxy carbonyl group of formula -COOR7; a carbonamido group of formula - NR8COR7; and hydrogen, when R1 is a branched or substituted alkoxy or a substituted phenoxy; R3 is hydrogen or an alkyl group; R4 is hydrogen, or an alkyl group; R5 is hydrogen or an alkyl group; R6 is an alkyl group. R7 is an alkyl group or a phenyl group; R8 is hydrogen or an alkyl group. Dummy dyes of the above specified type are advantageous in elements of the present invention in having good hues, good resistance to fading in weak or seasoned bleach solutions, and having good resistance to hue and density changes in cold storage.</p> |
