Abstract

PURPOSE:To obtain high sensitivity with spectral sensitivity in a near infrared region by forming one or more spectrally sensitized photographic silver halide emulsion layers and incorporating a specified compd. into at least one of the emulsion layers. CONSTITUTION:One or more photographic silver halide emulsion layers spectrally sensitized with at least one kind of sensitizing dye having max. spectral sensitivity in a wavelength region of >=700nm are formed and a compd. represented by formula I or II is incorporated into at least one of the emulsion layers. In the formulae I, II, each of n11, n12 and n21-n23 is a positive integer, n11 and n12 may be different from each other, n21-n23 may be different from each other, X is H or a metal atom, each of X11, X12 and X21-X23 is alkyl or aryl group, X11 and X12 may be different from each other and X21-X23 may be different from each other. A silver halide photographic sensitive material having high sensitivity with spectral sensitivity in a near infrared region and high shelf stability is obtd.
