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 (I) below: ##STR2## wherein: M is Cu, Co, Ni, Pd or Pt;W.sup.2, W.sup.3, W.sup.4 and W.sup.5 are defined in the specification.
