    • Novel pyrazolone photographic couplers contain in the coupling position a coupling-off group represented by the formula: ##STR1## wherein: L.sub.1 and L.sub.2 individually are unsubstituted or substituted methylene or ethylene;m and n individually are 0 or 1;Y is R.sub.1 or ZR.sub.2 ;R.sub.1 is an unsubstituted or substituted aryl or heterocyclic group, or is a secondary or tertiary carbon group represented by ##STR2## wherein R.sub.3 and R.sub.4 are selected from the group consisting of halogen, R.sub.2 and Z.sub.1 R.sub.b ; wherein Z is O, S, or NR.sub.a ; Z.sub.1 is O, S, or NR.sub.c ; and R.sub.2 is an unsubstituted or substituted alkyl, aryl, or heterocyclic group. R.sub.5, R.sub.6, R.sub.a, R.sub.b and R.sub.c are as defined in the specification. R.sub.3 optionally joins together with at least one of R.sub.4 and R.sub.5 to form one or two alicyclic or heterocyclic rings, which are optionally further substituted; andX represents the atoms selected from a group consisting of carbon, oxygen, nitrogen, and sulfur atoms necessary to complete a 5-, 6-, or 7-member unsaturated ring. This ring optionally contains further substituents than those indicated above, including other rings fused to the ring containing X.These couplers are useful in photographic elements and processes.
