Spectrally sensitized inner latent image type silver halide photographic emulsions

Claim 1

An inner latent image type silver halide photographic emulsion which is spectrally sensitized by adding at least one cyanine sensitizing dye represented by general formula (II) to a direct positive inner latent image type silver halide photographic emulsion and thereafter adding additionally at least one cyanine sensitizing dye represented by general formula (I) to said emulsion: ##STR9## wherein W and Y which may be identical or different from each other each represents an oxygen atom, a selenium atom, a sulfur atom or >N-R 5 , wherein R 5 represents a lower alkyl group which is unsubstituted or substituted with a halogen atom or a lower alkoxyl group or an allyl group, Z, Z 1 , Z 2 and Z 3 each represents an atomic group necessary to form a benzene ring or naphthalene ring, R and R 0 each represents a hydrogen atom, a lower alkyl group, a phenyl group or an aralkyl group, R 1 and R 2 each represents an alkyl group, a haloalkyl group, an alkoxyalkyl group, an aralkyl group, an aryloxyalkyl group or an allyl group, R 3 and R 4 each represents an alkyl group substituted with a carboxyl group or a sulfo group, but at least one of R 3 and R 4 represents an alkyl group substituted with a sulfo group, X 1 represents an anion, X 2 represents an anion or a cation, and n is 0 or 1.
