Claims
- 1. A photographic material which comprises at least one photosensitive silver halide emulsion layer and a development inhibitor releasing compound represented by the following formula;
- wherein Z represent non-metallic atoms necessary for forming a 5- or 6-membered heterocyclic ring, n represents an integer of 1 or 2 and R represents an alkyl, phenyl, alkylene or phenylene group provided that when n is 1, R represents an alkyl or phenyl group and when n is 2, R represents an alkylene or phenylene group.
- 2. A photographic material according to claim 1 wherein the heterocyclic ring is a tetrazole ring, benzotriazole ring or benzothiazole ring.
- 3. A photographic material according to claim 1 wherein the heterocyclic ring is a phenyl-substituted tetrazole ring.
- 4. A photographic material according to claim 1 wherein n is 1.
- 5. A photographic material according to claim 1 wherein R is an alkyl or alkylene group having 1 to 25 carbon atoms.
- 6. A photographic material according to claim 1 wherein R is an alkyl or alkylene group having 1 to 3 carbon atoms.
- 7. A photographic material according to claim 1 wherein R is an alkyl or phenyl group each of which is either unsubstituted or substituted by a electron donative group.
- 8. A photographic material according to claim 1 wherein the compound has a chemical structure of ##STR7##
- 9. A photographic material according to claim 1 wherein said photographic material further comprises a dye image forming substance.
- 10. A photographic material according to claim 9 wherein said photographic material further comprises an image-receiving layer.
- 11. A photographic material according to claim 9 wherein said dye image forming substance is a dye releasing redox compound.
