A METHOD OF MAKING AN ABRASION RESISTANT COATING ON A SOLID SUBSTRATE AND ARTICLES PRODUCED THEREBY.

摘要

There is disclosed a method for providing an improved abrasion resistant coating on solid substrates such as plastic articles and solid articles prepared thereby having on the surface such abrasion resistant coating. A solid substrate is coated with an organosiloxane coating liquid, the coating is cured, and subsequently post-treated by a glow discharge to afford an abrasion resistance far superior to that obtained from organosiloxane coating liquids without glow discharge post-treatment. The organosiloxane coating liquid comprises an organosilonal and/or a partial condensation product thereof. There is also disclosed a mirrored solid substrate such as a plastic having an improved abrasion resistance which has a glow discharge treated organosiloxane coating layer and a mirror layer deposited thereon by a vapor deposition method.
