摘要： The invention provides a photographic element comprising a silver halide emulsion layer having associated therewith an image dye-forming coupler of formula (I): ##STR1## wherein X is H or a coupling-off group, R is H; or R, R.sub.1 and R.sub.2 are the same or different and are coupler-modifying functional groups (with the provisos that (a) the moiety N(R.sub.1)COR.sub.2 may not be a carbamate, ureido or imido and (b) R.sub.1 and R.sub.2 may not both be phenyl or substituted phenyl); or R.sub.1 and R.sub.2 taken together with the nitrogen atom and the carbonyl group form a 5-10 membered heterocyclic ring which may contain one or more further heteroatoms selected from N, O and S, said heterocyclic ring being unsubstituted or substituted with one or more coupler-modifying functional groups, with the proviso that the ring is not a cyclic carbamate, ureido or imido; and wherein the coupler forms a dye with a peak absorption less than 565 nm.

摘要： The combination of a magenta dye image-forming coupler, such as a phenylpyrazolone, with a substituted phenol in a photographic material provides an enhancement in the light stability of the resultant magenta image dye.The phenol has the formula (I): ##STR1## wherein each R is the same or different and is an unsubstituted or substituted alkyl, halogen, cyano, SO.sub.2 R.sup.1, SO.sub.2 NHR.sup.1, NHSO.sub.2 R.sup.1 or COOR.sup.1 group, in which R.sup.1 is an unsubstituted or substituted alkyl or aryl group and n is from 1 to 5.The phenol may totally or partially replace the conventional coupler solvent. The combination is useful in single colour or multi-colour photographic silver halide emulsion materials and processes.
