摘要:
A silver halide photographic light-sensitive materials are described. In silver halide photographic printing paper comprising at least one silver halide photographic emulsion layer applied to a water impermeable reflective base, the printing paper of the present invention is in the improvement wherein said silver halide emulsion layer is spectrally sensitized with at least one cyanine dye represented by general formulae I and II, and an emulsified dispersion or latex dispersion of a water insoluble fluorescent whitening agent contained in a hydrophilic vehicle of at least one layer applied to the base on the same side as said silver halide emulsion layer: ##STR1## wherein Y.sub.1 and Y.sub.2 each represents an O atom, --N--R.sub.7 or a S atom, wherein R.sub.7 represents a lower alkyl group, A represents H or a lower alkyl group having 4 or less carbon atoms, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represents --H, --CH.sub.3, --OCH.sub.3, --C.sub.2 H.sub.5, --OC.sub.2 H.sub.5, --CN, --Cl, --F, --CF.sub.3, --COOH, --COOCH.sub.3 or --COOC.sub.2 H.sub.5, R.sub.5 and R.sub.6 each represents substituted or non-substituted lower alkyl group, but at least one of R.sub.5 and R.sub.6 is substituted by a sulfo group, and X represents an anionic residue.
