Abstract
A silver halide photographic light-sensitive material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein at least one hydrophilic colloidal layer containing said light-sensitive silver halide emulsion layer comprises the polymer latex stabilized by gelatin, and the outermost layer on the side containing said light-sensitive silver halide emulsion layer and/or the outermost layer on the other side comprises the anionic fluorine containing surfactant and/or cationic fluorine containing surfactant.
Claims7
A silver halide photographic light-sensitive material comprising a support having provided on a first side thereof, in order, at least one light-sensitive silver halide emulsion layer, and a protective layer, and, on a second side of said support, in order, a backing layer, and a backing protective layer, wherein at least one of the light-sensitive silver halide emulsion layer, the protective layer, the backing layer, and the backing protective layer contains polymer latex stabilized by gelatin, comprising latex that is reacted with gelatin after polymerization reaction, or latex polymerized in the presence of gelatin,
- at least one of said protective layer and backing protective layer comprising a surfactant selected from the group consisting of anionic fluorine-containing surfactants represented by Formula FA and cationic fluorine-containing surfactants represented by Formula FK;
- Formula FA
- Rf--A.sub.n Y
- wherein, Rf represents a fluorine substituted alkyl group or an aryl group having 3 to 30 carbon atoms, A represents a divalent group having 1 to 12 carbon atoms containing at least one bond of ##STR23## wherein R.sub.1 represents an alkyl group having 1 to 5 carbon atoms, n is 1 to 2, Y represents ##STR24## wherein M represents a hydrogen atom or cations of alkali metal, alkaline earth metal or quaternary ammonium salts;
- Formula FK
