    摘要: A multilayer polymeric film composite for use in the electrostatic recording process is disclosed. The film composite comprises an image receptive layer having a surface abrasivity of about 0.015 inch to about 0.085 inch and a surface .Iadd.Sheffield .Iaddend.roughness of about 30 to about 180 .[.cc of air/minute.]. (.Iadd.Sheffield Units).Iaddend., an electronically conductive layer and a supporting layer. A transport assisting layer can be coated on the side opposite to the imaging side to give a four layer film composite which provides the required friction and surface roughness to allow the film to be driven smoothly through the printing equipment. Control of the abrasivity and surface roughness of the image receptive layer is used to obtain excellent image quality. The film composite provides high image quality over a wide range of humidities and archival properties.
