Abstract

A plastic film with an antistatic layer and a silver halide photographic light-sensitive material using the film as the support are disclosed. The antistatic layer comprises a water-soluble electric conductive polymer and particles of a hydrophobic polymer, and hardened with a hardening agent. The hydrophobic polymer has an N-methylol or its derivative group, an amino group, an epoxy group, an aziridine group, an active methylene group, a sulfinic acid group, an aldehyde group, a vinylsulfonyl group or a blocked isocyanate group. A silver halide photographic material using the film having the inventive antistatic layer is excellent in layer adhesion and sufficiently protected from static charge even after processing.
