Abstract
The invention concerns a process for reducing, or completely eliminating, traces of abrasion or scratches on the surface of a record carrier covered with a thin metallic layer, preferably consisting of aluminum. The process is characterized in that the surface of the record carrier is covered with a 2 to 1000 nm thick layer of a metallic soap, preferably a saturated metallic soap, an unsaturated metallic soap or a mixture thereof.
Claims8
A process for reducing traces of abrasion during printing operations in an electrographic printer, on the surface of a record carrier covered with a thin evaporated aluminum layer, said process being characterized in that a thin layer of about 2 nm to 1000 nm of a metallic soap is applied to said layer in such a manner that the inherent unevenness of the surface of the record carrier is essentially leveled out and compensated.
