ABSTRACT:
An electrostatic latent image in a desired pattern is formed on an electrostatically imageable surface and toned with a liquid toner to form a toner image on the surface. The toner image is then transferred while still wet to a transfer sheet and then to the surface of a conductor, or the toner image may be transferred directly to the surface of a conductor without a transfer sheet, such direct transfer being preferred. The toner image is then fused to the conductor surface to provide an etch resist pattern of high resolution on the conductor surface. The conductor may then be etched to form a high density printed circuit. In the direct transfer method a nonpolar insulating solvent-carrier is applied to the surface of the conductor and the electrostatically imageable surface.
