    摘要: A photographic element having at least one photosensitive silver halide layer and associated therewith both a particular type of color coupler and a particular type of stabilizer. The color coupler is of the general formula (1) or (2): ##STR1## wherein A and B represent the same or different electron-withdrawing group,X is H or a group which splits off on coupling with oxidized color developer,R is an alkyl, cycloalkyl, aryl or heterocyclic which may be substituted, --COR.sup.1, --CSR.sup.1, SOR.sup.1, SO.sub.2 R.sup.1, --NHCOR.sup.1, --CONHR.sup.1, --COOR.sup.1, --COSR.sup.1, --NHSO.sub.2 R.sup.1 wherein R.sup.1 is an alkyl, cycloalkyl, or aryl group any of which are optionally substituted, and wherein two or more of A, B, R, and X optionally form part of a ring,Link is a linking group andn is 0, 1 or 2.The stabilizer is of the general formula: ##STR2## wherein: E.sup.1, E.sup.2, W.sup.2 and W.sup.3 may independently be a hydrogen atom, a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aromatic group, an acylamino group, a mono or dialkylamino group, an aliphatic or aromatic thio group, an aliphatic or aromatic oxycarbonyl group, or W.sup.2 and W.sup.3 in combination with the benzene ring may independently represent the atoms necessary to complete a fused ring system, or E.sup.1 and W.sup.3 together, and E.sup.2 and W.sup.2 together, may independently form a heterocyclic ring with an O.
