Electrostatic images which are developed with liquid devel-opers containing alkyd or similar resins are difficult to transfer to various substrates, for example polymer sheets, because the alkyd resins become firmly bonded to photoconduc-tor surface materials such as selenium. This problem has been overcome by spray coating the alkyd resin developed images upon the photoconductor surface with a polymer material containing a surfactant or other agent which at least reduces the bond between the alkyd resin and the photoconductor surface; drying the coated developed image on the photocoriduc-tor surface and transferring the dried coated developed image to receiver sheets (substrates) by pressure transfer. This process permits the transfer of alkyd resin containing developed images to polymer substrates to form high resolution transparencies. It appears that the surfactants or other agents incorporated in the polymer reduce the adhesion or bond between the alkyd resin and the photoconductor material such as selenium.
