Silver halide photographic material having improved antistatic properties
First Claim
1. A silver halide photographic material comprising a support, at least one silver halide emulsion layer coated thereon, and a hydrophilic colloid layer coated over said at least on silver halide emulsion layer, wherein said hydrophilic colloid layer comprises a combination of (a) at least one surfactant selected from the group consisting of non-ionic perfluoroalkyl(ene)poly-oxyalkylene surfactants and polyoxyethylene-modified polysiloxane surfactants, and (b) at least one salt selected from the group consisting of salts of perfluoroalkylsulfonyl imides and salts of perfluoroalkylsulfonyl methides.
