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 electrophotographically forming a toned latent electrostatic image of a document upon an electrophotographic member, bringing the 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 fully 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. |
