    • PURPOSE: To obtain high sensitivity as well as a significant toning effect by incorporating a specified compound into the image receiving layer of a photographic element for the diffusion transfer of silver salt to be processed with a processing composition contg. a hydroxylamine developer, a solvent for silver halide and alkali.
      CONSTITUTION: A compound represented by formula I (where R
      1 is H, 1W6C alkyl or the like, and R
      2 is H, 1W6C alkyl or the like) is incorporated into an image receiving layer as a toning agent by 10
      -8 W10
      -3 mol/m
      2 . The preferred compound has CH
      3 and R
      1 and H as R
      2 or two CH
      3 groups as R
      1 and R
      2 . A compound represented by formula II (where R
      3 is H or 1W6C alkyl) may be combined with the compound represented by the formula I by 1×10
      -6 W1× 10
      -2 mol/m
      2 to improve the sensitivity. The preferred compound represented by the formula II has H, CH
      3 or n-C
      3 H
      7 as R
      3 . The compounds represented by the formulae I , II may be added to a processing composition, or the compound represented by the formula II may be incorporated into the image receiving element while adding the compound represented by the formula I to the processing composition.
