Photographic elements containing naphthylsulfonylethylthio heterocycle developement inhibitor precursor |
| abstract |
A photographic element comprised of a support having provided thereon at least one silver halide emulsion layer, the element containing a development inhibitor precursor, is disclosed. The development inhibitor precursor is a compound represented by following general formula (I): <IMAGE> (I) wherein A represents an unsubstituted or substituted phenyl group or a 5-membered or 6-membered nitrogen-containing heterocyclic ring; Q represents a naphthalene skeleton; R1, R2, and R3, which may be the same or different, independently represent a hydrogen atom or a monovalent substituent; and n represents 1 or 2. The photographic element gives improved image quality particularly in the low Dmin area. The element can be processed over a wide range of different processing temperatures and has improved preservability. |
