PROBLEM TO BE SOLVED: To provide a photographic element containing a heterocyclic dye-forming coupler capable of producing an azomethine dye having improved light stability. SOLUTION: Structure I: embedded image (Wherein Z is, together with nitrogen, an element C required to complete a substituted or unsubstituted 5- or 6-membered heterocyclic group, Halogen, in combination with a novel pyrazolo [5,1-c] triazole dye-forming coupler having N, O or S, R 1 represents a substituent and X represents hydrogen or a coupling-off group). A photosensitive photographic element comprising a support carrying a silver emulsion. |
