<p>A photographic element comprising a support having thereon at least one silver halide emulsion layer having associated therewith a dye-forming coupler and a dye stabilizer comprising a bisphenol derivative having two linked phenol rings, one of the phenolic hydroxy groups being substituted and at least one of the phenol rings being substituted. In a preferred embodiment, the bisphenol derivative has the following formula: <CHEM> wherein A is a substituted or unsubstituted alkyl, cycloalkyl, alkenyl, aryl, acyl, alkylsulphonyl or arylsulphonyl group; X is a single bond or a linking group selected from alkylene, alkylidene, a heteroatom or sulphonyl; and, each R independently represents one or more substituents, each substituent independently being a substituted or unsubstituted alkyl, alkenyl, cycloalkyl or aryl group; or each R in combination with the benzene ring to which it is attached independently represents the atoms necessary to complete a fused ring system.</p> |
