Photographic elements containing cyan coupler UV absorber and stabilizer

A photographic element comprising at least one light-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a UV absorber and a stabilizer wherein the stabilizer has the formula (IB)

• wherein
• R1 and R1 are independently selected from hydrogen, an unsubstituted or substituted alkyl, aryl, alkoxy, aryloxy group or a substituted amino group;
• or R1 and R1 may combine to complete a 5-10 membered heterocyclic ring which may contain, in addition to Si, 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;
• and
• X is a single bond or a linking group having an atom which connects the arene or heteroaromatic ring systems;
• or
• X forms, together with substituents ortho to X on the arene 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.

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, a UV absorber and a stabilizer of formula (I)

• wherein
• Y is phosphorous, silicon or boron;
• R1 and R1 are independently selected from an unsubstituted or substituted alkyl, aryl, alkoxy, aryloxy group or a substituted amino group;
• n is 0 or 1:
• provided also that when
• (a) Y is phosphorous, n is 1 and R1 is oxygen (═O);
• (b) Y is silicon, n is 1 and R1 and/or R1 may also be hydrogen or R1 and R1 may combine to complete a 5-10 membered heterocyclic ring which may contain, in addition to Y, one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted;
• and
• (c) Y is boron, n is 0;
• each Z independently represents the atoms necessary to complete a substituted or unsubstituted arene or heteroaromatic ring system;
• and
• X is a single bond or a linking group having an atom which connects the arene or heteroaromatic ring systems;
• or
• X forms, together with substituents ortho to X on the arene 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.

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, a UV absorber and a stabilizer of formula (I)

• wherein
• Y is phosphorous, silicon or boron;
• R1 and R1 are independently selected from an unsubstituted or substituted alkyl, aryl, alkoxy, aryloxy group or a substituted amino group;
• n is 0 or 1:
• provided also that when
• (a) Y is phosphorous, n is 1 and R1 is oxygen (═O);
• (b) Y is silicon, n is 1 and R1 and/or R1 may also be hydrogen or R1 and R1 may combine to complete a 5-10 membered heterocyclic ring which may contain, in addition to Y, one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted;
• and
• (c) Y is boron, n is 0;
• each Z independently represents the atoms necessary to complete a substituted or unsubstituted arene or heteroaromatic ring system;
• and
• X is a single bond or a linking group having an atom which connects the arene or heteroaromatic ring systems;
