ABSTRACT:
There is disclosed a silver halide photographic light-sensitive material that comprises, in at least one photographic layer constituting the material, a dispersion containing fine grains of a solid dye represented by the following general formula (II), wherein the solid dye has been subjected to heat treatment at 40.degree. C. or higher, and wherein the dispersion further contains a specific water-soluble or water-dispersible polymer-compound that has a hydrophobic group bonding at a terminal of a copolymer of vinyl alcohol and vinyl ester: ##STR1## wherein D represents a residue of a compound having a chromophoric group; X represents a dissociating hydrogen atom, or a group having a dissociating hydrogen atom, which atom or group connects to the D directly or via a divalent connecting group; and y is an integer of 1 to 7. The photographic light-sensitive material prevents any change of viscosity with the lapse of time due to the dye in a state of dispersion solution containing fine grains of the dye. The material does not cause any change of absorption spectral due to the dispersion solution containing the fine grains.
