    摘要: A novel color diffusion transfer photographic element is disclosed which is characterized as having a photosensitive element containing a compound represented by the formula ##STR1## wherein A represents oxygen or a group of the formula .dbd.NR (in which R represents hydroxyl or an amino group); X represents hydrogen or halogen; Z represents a group of nonmetallic atoms necessary to form a first ring and being a 5 to 7-membered nonaromatic hydrocarbon ring which may be fused with a second ring, at least one of said first ring and said second ring having one or more substituents wherein at least one of said substituents is a ballast group which renders said compound nondiffusible during processing with said solution; J represents a divalent group; D represents a dye moiety or a dye precursor moiety; and n represents zero or 1.
