A silver halide photographic light-sensitive material having at least one antistatic layer, said antistatic layer containing a dispersion of polymer represented by the following formula (I): ##STR1## wherein A represents a monomer unit formed from a copolymerizable monomer having at least two ethylenically unsaturated groups, B represents a monomer unit formed from a copolymerizable and monoethylenically unsaturated monomer, R.sub.1 represents a hydrogen atom or a lower alkyl group having 1 to 6 carbon atoms, Q represents a divalent group containing 1 to 12 carbon atoms, R.sub.2, R.sub.3 and R.sub.4 may be the same or different and each represents an alkyl group containing 1 to 20 carbon atoms, or an aralkyl group containing 7 to 20 carbon atoms, or R.sub.2, R.sub.3 and R.sub.4 may combine to form a ring together with the nitrogen atom, X.sup..crclbar. represents an anion, x is about 0.25 to 10 mol%, y is about 0 to 90 mol%, and z is about 10 to 99 mol%.

Antistatic silver halide photographic light-sensitive material

A silver halide photographic material having improved anti-static properties comprising a support having thereon at least one silver halide emulsion layer and which contains in an outermost layer of the photographic material, in a layer contiguous to a subbing layer for a silver halide emulsion layer in the photographic material, and/or in a layer contiguous to the outermost layer provided on the opposite side of the support to that on which the silver halide emulsion layer is present in the photographic material a compound having a molecular weight of about 1,000 to about 50,000 and a recurring unit represented by the following general formula (I) ##STR1## R.sub.1 and R.sub.2, which may be the same or different, each represents an alkyl group, a cycloalkyl group, an aralkyl group, an aryl group or an alkenyl group, or R.sub.1 and R.sub.2 can combine and form an alkylene chain; R.sub.3 represents an alkylene group or an aralkylene group having 10 or less carbon atoms; and X.sub.1.sup.- and X.sub.2.sup.- each represents an anion; and a method for preventing the generation of static charges in a photographic material.
