The invention provides a photographic element comprising at least one light-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, UV absorber and (A) a stabilizer of formula (I) wherein R1 is an unsubstituted or substituted alkyl or aryl group or a 5- to 10- membered heterocyclic ring which contains one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted; Z is a hydrogen atom or a substituent group; X is a group selected from —SO2—, —SO—, —COO—,—CO— and —CS—, W is one or more unsubstituted or independently substituted alkylene groups connecting the nitrogen atom to X, and p is 0 or 1; R2 is a substituent group; or the groups represented by Z and R2 can be joined to form a ring which may be substituted; and (B) a high-boiling solvent of formula (II) wherein R3 is an unsubstituted or substituted alkyl or aryl group; and G is an unsubstituted or substituted alkyl group. The invention provides improved light and dark stability in a photographic element without degradation in hue or reactivity of the dyes therein.
A photographic element comprising at least one light-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, UV absorber and
A multi-colour photographic element comprising a support bearing yellow, magenta and cyan image-dye-forming units comprising at least one blue-, green- or red-sensitive silver halide emulsion layer having associated therewith at least one yellow, magenta or cyan dye-forming coupler respectively, wherein the element comprises at least one light-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, UV absorber and
A process of forming an image in a photographic element after the element has been imagewise exposed to light, comprising contacting an element with a colour developing agent, wherein the element comprises at least one light-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, UV absorber and
