Pressure sensitive adhesive drafting films for use in electrostatographic copiers

Abstract

Disclosed is a novel pressure sensitive adhesive drafting film which is specially formulated to permit it to be imaged in electrostatographic copiers. The film is a multilayered structure comprising layers from the top down of: (a) a matte coating capable of receiving and holding graphic information; (b) a layer of organic resinous material in film form; (c) a layer of pressure sensitive adhesive; (d) a release coating; (e) a layer of an organic resinous material in film form as release liner; and (f) a back coating which is a layer of an organic resinous binder material having dispersed therein: I. a particulate solid material of particle size ranging from 3 to 20 microns in the longest dimension, and Ii. a water insoluble antistatic agent of a type to cause the film to have a surface resistivity in the range of from 10.sup.9 to 10.sup.14 ohms/sq.
