    • The invention relates to a photographic element comprising a light sensitive silver halide emulsion layer having associated therewith one or more dye-forming couplers and a stabilizer compound of formula (I): 1 wherein R1 and R2 are independently selected from hydrogen or an unsubstituted or substituted alkyl, aryl, alkoxy, aryloxy or amino group or may combine to complete a 5-10 membered heterocyclic ring which may contain in addition to the silicon atom one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted; each Z independently represents the atoms necessary to complete a substituted or unsubstituted arene or heteroaromatic ring system; X is a single bond or a linking group having a single atom which connects the arene rings or heteroaromatic ring systems, or X forms, together with substituents ortho to X on the arene rings or heteroaromatic ring systems, a fused unsubstituted or substituted 5-, 6-or 7-membered ring, which may contain one or two heteroatoms selected from nitrogen, oxygen and sulfur. The stabilizer is used to enhance the image stability of the dye formed from a cyan, magenta or yellow dye-forming coupler without significantly degrading other photographic properties.

    • A method for reproducing a color image. A dye image is formed on a photographic light-sensitive material by imagewisely exposing the material and processing to form a dye image. Through the imaged photographic light-sensitive material, an exposure is made on a photographic printing light-sensitive material which is processed in an alkaline activator solution to form a dye image thereon. The photographic light-sensitive material contains a transparent support provided thereon with red-sensitive, green-sensitive, and blue-sensitive silver halide emulsion layers. The layers each contain one of three different nondiffusible couplers capable of forming, by coupling, compounds having spectral absorption maximum wavelength in the wavelength region longer than 340 nm. The spectral absorption maximum wavelength of the compounds differ by at least 30 nm. The blue-sensitive layer contains a coupler capable of forming the compound having the highest molecular extinction coefficient among the three different couplers, whereas the green-sensitive layer contains a coupler capable of forming the compound having the lowest molecular extinction coefficient. The printing light-sensitive material contains a support provided thereon with three different light-sensitive silver halide emulsion layers respectively having spectral sensitivity corresponding to the absorption maximum wavelength of the compounds formed in the photographic light-sensitive material. The layers each comprise one of three nondiffusible yellow, magenta, and cyan couplers, and contain a color developing agent and/or the precursor thereof.
