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.
Claims19
The method of electrosensitive recording which comprises:
- applying an electrically actuated printhead to a metallic surface and an underlying contrast layer comprised of crystalline silicon dioxide, a polyolefin, a pigment or dye, and a film forming resin;
- and
- electrically penetrating the metallic surface to selectively expose portions of said underlying contrast layer;
- wherein the components in said contrast layer protect against the removal of the metallic surface while the printhead moves in contact across the surface at intervals between electrical actuations.
The method of preparing an electrosensitive recording material which comprises:
- applying to a support a contrast material comprising crystalline silicon dioxide, a resin, a pigment or dye, and a polyolefin having a specific gravity less than the resin;
- drying said polyolefin to form a layer on the surface of the contrast material;
- and
- depositing a metallic layer on the contrast material adjacent the polyolefin layer.
Electrosensitive recording material comprising:
- a support;
- a contrast material upon said support including a film forming resin, a filler comprised of crystalline silicon dioxide, a pigment or dye, and a polyolefin;
- and
- a metallic layer upon said contrast material;
- wherein said polyolefin comprises a layer on the surface of the contrast material adjacent the metallic layer;
- wherein said contrast material reduces the removal of the metallic layer as a printhead moves in contact across said layer at intervals between electrical actuations of the printhead.
