摘要：
A photographic development inhibitor releasing compound comprises a releasable development inhibitor group comprising an amide group containing a carbon alpha to the amide functionality which is di- or tri-fluorinated. Such a compound is useful in photographic silver halide materials and processes to enable increased image sharpness and good interimage results.
