Abstract
Electroreprographic films comprising a support member which are capable of acquiring an electrostatic charge which on passing through a toner bath pick up unwanted toner outside the image area which is not fixed during development. The unwanted toner pick up is minimized by applying a layer of anti-static material to the otherwise uncoated back of the support.
Claims4
A method for substantially preventing unwanted toner pick up on an electroreprographic imaging element having a film support layer, a conductive layer on said support, and a dielectric layer on said conductive layer, said method comprising application to the uncoated side of said film support an antistatic coating capable of substantially eliminating static electrical charges on the antistatically coated side of the film, said antistatic coating comprising a material selected from the group consisting of inorganic salts, resinous polymers of quaternary ammonium salts, homopolymers and copolymers of vinyl organic quaternary ammonium compounds and esters thereof.
