摘要: The present invention discloses a three layer backing system for a photographic element. The backing system in on the opposite side of the light-sensitive layer. The backing system includes a first antistatic layer having an antistatic agent. The backing system includes a barrier layer of a polymer. The overcoat layer, farthest from the support, includes cellulose acetate and cellulose nitrate in a ratio range of from 3:1 to 1:1 and from 5 to 40 percent perfluorinatied polymer particles.
