Photographic support material comprising an antistatic layer and a barrier layer
 Photographic support materials are comprised of a conventional support, such as polyester film, cellulose acetate film or resin-coated paper, having thereon an antistatic layer comprising vanadium pentoxide and an overlying barrier layer comprised of a latex polymer having hydrophilic functionality. The barrier layer provides excellent adhesion between the antistatic layer and overlying layers, such as silver halide emulsion layers or curl control layers, and also prevents unwanted diffusion of the vanadium pentoxide; whereby the combination of antistatic and barrier layers serves to impart a high level of permanent antistatic protection.
