Abstract
An electroconductive coating composition for a plastics substrate, such as a poly(ethylene terephthalate) film, comprises a polymeric electrolyte and a polyepoxy resin. Surface conductivity may be promoted by the inclusion of an enhancer or by treatment with an interactive solvent medium. Substrates coated with the composition exhibit substantially permanent antistatic characteristics when subjected to photographic processing techniques.
