Abstract (en)

A silver halide photographic light-sensitive material is disclosed, which is improved in anti-adhesion in a high humid condition. The light-sensitive material comprises a support having thereon a photographic component layer, which comprises a silver halide emulsion layer and optionally a hydrophilic colloid layer in which the silver halide emulsion layer comprises silver halide grains having a silver chloride content of not less than 90 mol % and the outermost layer provided at the position farthest from the surface of the support of said photographic layer contains a fluorinated cationic surfactant represented by formula I; <CHEM> wherein R2 is a hydrogen atom or an alkyl group having 1 to 5 carbon atoms; R3, R4 and R5 are each independently a hydrogen atom, an alkyl group having 1 to 5 carbon atoms or a hydroxyalkyl group; X<-> is Br<->, Cl<->, CH3SO3<->, CH3-C6H4-SO3<->, CH3COO<->, NO3<-> or C6H5-SO3<->; n is an integer of 1 to 10; m is an integer of 1 to 6; l is 0 or 1; and k is an integer of 0 to 5, provided that k is not 0 when l is 1.
