Abstract
Elements having a support with lubricant on both sides can be treated to remove substantially all of the lubricant from one side only. Various chemical, mechanical and electrical treatments are contemplated, but glow discharge treatment is particularly useful. Photographic film supports having one or more layers applied thereto can be treated in this manner before or after annealing so that lubricant present on the treated side does not reduce adhesion of later applied silver halide emulsion layers.
