Abstract of the Disclosure An electrostatically imageable drafting film comprises a plastic, impermeable, non-conductive film support carrying an electrically conductive coating which is in turn coated with a dielectric layer containing a silicious toothing pigment. This last layer is capable of receiving indicia using as marking materials ink, pencil, crayon and the like. The last layer is actinically transparent to permit the drafting film to be used as a mask for diazo reproduction.
