Abstract There is disclosed a photographic element comprising a support having thereon a layer containing an anilino-type magenta coupler, wherein said layer comprises an organic solvent having a dielectric constant of not greater than 6.5 and a metallic complex having the following formula (1), (11) or (III) : wherein M is nickel, copper, cobalt, palladium or platinum; X, and X 2 each is hydrogen, sulfur or -NR 5 , wherein R 5 is hydrogen or an alkyl, aryl or hydroxyl radical; X 3 is a hydroxyl or mercapto radical; Y is oxygen or sulfur; R 1 , R 2 , R 3 and R 4 each is hydrogen atom, a halogen, a cyano radical, or an alkyl, aryl cycloalkyl or heterocyclic radical which each is bonded directly or through a divalent combining radical to a carbon atom, provided at least one of the R 1 -R 2 and R 3 -R 4 combinations is allowed to form a 5- or 6-member cyclic ring by combining with the carbon atoms which are bonded with each other; and z is a compound coordinatable to M. By incorporating of such a metallic complex compound there can be improved the light resistance of a dye image formed with said photographic element.
