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.
Claims4
A coated article comprising a polymeric substrate having, on at least one surface thereof, an electroconductive layer of a composition, wherein the composition comprises a polymeric electrolyte and a polyepoxy resin in a weight ratio from 1:20 to 1:0.5, the polymeric electrolyte being a cationic electroconductive polymer capable of conducting a current through ionization.
