Zusammenfassung:There is disclosed a silver halide photosensitive material for use under room-light wherein at least one silver halide emulsion layer contains (1) a spectrally unsensitized negative silver halide having an average grain size of 0.1 to 0.3 mu m and containing at least 80 mol % of silver chloride and (2) an organic desensitizer having an anodic polarographic potential and a cathodic polarographic potential which give a positive sum and this photosensitive material satisfying at least one of the following requirements: (a) said emulsion has undergone substantially no chemical ripening; a spectrally non-sensitizing dye capable of absorbing chiefly the rays in the range of from about 500 to 600 nm is contained in at least one of said photographic layers; and (c) at least one of the compounds from (i) to (v) as disclosed in the specification is contained in said emulsion layer.
