Spectrally sensitized prefogged direct-positive silver halide photographic material |
摘要 |
The present invention provides a photographic material with a pH at 25 DEG C of at most 7, containing on a support at least one layer, comprising a prefogged direct-positive silver halide emulsion spectrally sensitized with one or more electron-accepting sensitizing dyes in a total amount of at least 0.15 mmole/mole silver halide, the silver halide crystals of said prefogged direct-positive silver halide emulsion containing silver chloride for at least 60 mole %, silver bromide in a range from 0.5 mole % to 39.98 mole % and silver iodide in a range from 0.02 mole % to 2 mole %, characterized in that said silver halide cristals contain silver iodide for at least 0.20 mmole/mole AgX in the outer 10% by weight of said cristals and said layer contains a gelatin species containing Ca<2><+> in an amount ranging from 0.2 % to 1 % by weight.
