Abstract
A plastic film or coated paper has a hydrophilic colloid layer thereon comprising particles with the average particle size of 0.5 to 20.mu. coated with a water-repellent material. The water-repellent material is selected from the group consisting of silicone, a silane compound, a fluorine-containing compound and a silane coupling agent. A silver halide photographic light-sensitive material comprises a hydrophilic colloid layer comprising particles with the average particle size of 0.5 to 20.mu. coated with a water-repellent material.
Claims3
