发明名称 Silver halide photographic light-sensitive material containing a dispersion of solid fine grains
摘要 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 DEG 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: D(X)y formula (II) 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.
