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 X2 each is hydrogen, sulfur or -NR5, wherein R5 is hydrogen or an alkyl, aryl or hydroxyl radical; X3 is a hydroxyl or mercapto radical; Y is oxygen or sulfur; R1, R2, R3 and R4 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 R1-R2 and R3-R4 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.
本发明公开了一种照相元件,该元件包括一个支架,支架上有一层含有苯胺型品红耦合剂的层,其中所述层包括介电常数不大于 6.5 的有机溶剂和具有下式 (1)、(11) 或 (III) 的金属络合物:
其中 M 是镍、铜、钴、钯或铂;X 和 X2 各自是氢、硫或-NR5,其中 R5 是氢或烷基、芳基或羟基;X3 是羟基或巯基;Y 是氧或硫;R1、R2、R3 和 R4 各自是氢原子、卤素、氰基或烷基、芳基环烷基或杂环基,它们各自直接或通过二价结合基键合到碳原子上,条件是 R1-R2 和 R3-R4 组合中至少有一个可通过与相互键合的碳原子结合形成 5 或 6 元环;以及 z 是可与 M 配位的化合物。通过加入这样的金属复合物,可以提高用所述感光元件形成的染料图像的耐光性。
