Abstract
Electrosensitive recording using a composite structure formed by a base support for a resinous contrast layer containing amorphous silicon dioxide, polycrystalline silicon dioxide, and a polyolefin, which provide an anti-abrasion characteristic. The contrast layer has an overlying metallic surface that is desirably provided by vapor deposition. The electrostatic structure provides suitable print quality for information recorded by electrically actuated styli and has the property of suitable resistance to unwanted stripping or burnishing of the metallic surface.
