Abstract
Abstract A silver halide photographic light-sensitive material is disclosed. The light-sensitive material comprises a support having a dielectric constant for 100 Hz of not larger than 2.80 having thereon, a silver halide emulsion layer and a particle-containing layer comprising non-light-sensitive fine particles having a volume resistivity of from 10 -2 Ω.cm to 10 8 Ω.cm.
