Photographic element containing cyan dye-forming coupler

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 a light sensitive silver halide emulsion layer having associated therewith (A) a cyan dye-forming coupler of formula (I) and (B) a bisphenol derivative compound of formula (II):

• wherein
• each R1 is a substituent provided that at least one of these is a fluoro or a perfluoroalkyl substituent;
• n is an integer from 1 to 3;
• R2 is an unsubstituted or substituted alkyl, aryl, amino or alkoxy group or a 5-10 membered heterocyclic ring which contains one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted;
• and
• COG is a hydrogen atom or a group which can be split off by the reaction of the coupler with an oxidized colour developing agent,
• provided that
• (a) when n is 3 and each R1 is fluorine, COG is not a methoxy group and
• (b) when n is 2 and R1 in the 3- and 4-positions is each a fluorine atom, COG is not hydrogen;
• wherein
• R3 is an unsubstituted or substituted alkyl, aryl, alkoxy, aryloxy group or a substituted amino group;
• 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 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 a light sensitive silver halide emulsion layer having associated therewith (A) a cyan dye-forming coupler of formula (I) and (B) a bisphenol derivative compound of formula (II):

• wherein
• each R1 is a substituent provided that at least one of these is a fluoro or a perfluoroalkyl substituent;
• n is an integer from 1 to 3;
• R2 is an unsubstituted or substituted alkyl, aryl, amino or alkoxy group or a 5-10 membered heterocyclic ring which contains one or more heteroatoms selected from nitrogen, oxygen and sulfur, which ring is unsubstituted or substituted;
• and
• COG is a hydrogen atom or a group which can be split off by the reaction of the coupler with an oxidized colour developing agent;
• provided that
• (a) when n is 3 and each R1 is fluorine, COG is not a methoxy group and
• (b) when n is 2 and R1 in the 3- and 4-positions is each a fluorine atom, COG is not hydrogen;
• wherein
• R3 is an unsubstituted or substituted alkyl, aryl, alkoxy, aryloxy group or a substituted amino group;
• 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 or heteroaromatic ring systems;
