Direct positive silver halide photographic material |
摘要 |
Significant improvement in color reproduction can be achieved by a direct positive silver halide color photographic material having at least one each of a blue-sensitive, green-sensitive and a red-sensitive direct positive silver halide emulsion layer, in which material at least one of said direct positive silver halide emulsion layer contains both silver chloride or a silver halide composed of silver chlorobromide or silver chloroiodobromide containing no less than 50 mol % of AgCl, and a specific compound that is capable of reacting with the oxidation product of a developing agent to release a specific compound capable of scavenging said oxidation product or a precursor of said scavenging compound.
