<p>An electrostatic transfer medium comprising a sheet formed of a transparent polyester plastic substrate having a thin transparent coating of a compatible polyester resinous composition having a softening range less than the softening range of the substrate material. A high resolution transparency is formed by electrophotograpically forming a toned latent electrostatic image of a document upon an electrophotographic member, bringing a transfer medium into engagement with the image under localized pressure and heat to form a laminate and separating the cooled laminate whereby the image is transferred in its entirety, intact, to the coating, the transfer being effected with minimal loss of optical density or resolution and practically no residue remaining on the electrophotographic member. The laminate may be cooled prior to separation.</p> |
