Abstract
A silver-halide/gelatin light-sensitive emulsion containing a saturated cyclic oxime compound, and optionally containing a di- or trimethylol lower alkane compound is disclosed. The light-sensitive emulsion coated on a substrate is particularly useful as a radiographic film.
Claims15
A photographic silver halide emulsion comprising a silver halide dispersed in a binder and at least one saturated cyclic oxime compound having the oximido group attached to a ring carbon, said saturated cyclic oxime compound being present in an amount sufficient to increase the covering power and contrast of the developed silver of the silver halide emulsion.
A silver halide light-sensitive element comprising a support having coated on at least one surface thereon a silver halide containing emulsion, said emulsion having therein at least one saturated cyclic oxime compound having the oximido group attached to a ring carbon, said saturated cyclic oxime compound being present in an amount sufficient to increase the covering power and contrast of the developed silver of the silver halide emulsion.
