Silver halide photographic material comprising two kinds of monodisperse emulsions differing in mean grain size |
| abstract |
A silver halide photographic material comprising at least one negative type silver halide emulsion layer coated on a support, said emulsion comprising two kinds of monodisperse emulsions each having a means grain sizes of not more than 0.5 micron and, differing in mean grain size from each other at least by 0.1 micron, and said photographic material further comprising a hydrazine derivative in at least one photographic layer, whereby negative images of high density and very high contrast can be obtained with a high photographic speed and without black spots. |
