(54)Silver halide element with improved high temperature storage


(57) This invention relates to a silver halide photographic element comprising at least one silver halide emulsion layer containing a dye-forming coupler which reacts with an oxidized color developing agent to form dye, said silver halide element further comprising an amido compound of Formula I
  • wherein INH is a development inhibitor;
  • LINK is a linking or timing group and m is 0, 1 or 2; and
  • wherein INH is a development inhibitor;
  • R1 and R2 independently represent an aliphatic, aromatic or heterocyclic group, or R1 and R2 together with the nitrogen to which they are attached represent the atoms necessary to form a 5 or 6 membered ring or multiple ring system, or R1 and R2 are independently a -C(=O)(LINK)m -INH group, or are substituted with an -NR3aC(=O)-(LINK)m -INH group, with R3a being defined the same as R1 or R2, and wherein the compound of Formula I does not substantially react with oxidized developer to release INH.
