Abstract
Abstract A silver halide photographic light-sensitive material is disclosed which is improved in antistatic property. The photographic material comprises a support, a silver halide emulsion layer and an antistatic layer comprising a water-soluble conductive polymer, a hydrophobic polymer particle and a silane coupling agent represented by the following Formula I: ##STR1## wherein X is an oxygen atom or a --OCO-- group; R 1 , R 2 , R 3 and R 4 are each an alkyl group or an aryl group which may be the same or different and are allowed to be substituted, and at least one of the groups represented by R 1 , R 2 , R 3 and R 4 is a group containing a double bond, a halogen atom, an epoxy group, an acid anhydride residue, an alkoxy group, an alkoxycarbonyl group, an amino group, an acryloyl group, a methacryloyl group, an acrylamido group, a methacrylamido group or a haloacylamino group; n 1 , n 2 and n 3 are each 0 or 1, which may be the same or different, provided that the total of n 1 , n 2 and n 3 is 1 or more.
