Light-sensitive silver halide photographic material for forming direct-positive images and method for making same

A black-and-white silver halide photographic material has been disclosed, coated on a support with at least one light-sensitive emulsion layer, comprising a spectrally sensitized prefogged direct-positive silver halide emulsion, providing peak absorption in the wavelength range from 600 nm up to 700 nm, wherein said emulsion comprises a binder and core-shell emulsion crystals having silver bromide in a total amount of at least 80 mole %, characterized in that said emulsion is spectrally sensitized with a combination of a desensitizing dye having an absorption maximum wavelength in a range from 600 nm up to 700 nm, if present as a sole dye in said emulsion, and at least one azacyanine dye having an absorption maximum at a more hypsochromic wavelength.
