摘要： A photographic base is protected against the adverse effects resulting from the accumulation of static electrical charges by providing it with a first antistatic hydrophilic layer and a second protective hydrophobic layer coated onto said first layer, said first layer having been formed by coating onto said base a liquid coating composition comprising a hydrophilic non-diffusing sulfonated polymer in the presence of an epoxy-silane compound. The antistatic base is particularly useful for photographic elements comprising at least one photosensitive image-forming layer, on one side thereof, and the first antistatic layer and the second protective layer on the opposite side thereof. The antistatic layer is durable, abrasion-resistant, non-tacky and can withstand the aqueous photographic processings without adverse effects.
