Abstract
A composite material for optical use as well as the method for obtaining it. This material includes a substrate made from a thermoplastic copolyester, a layer of polyurethane bonding primer, and a silicone anti-scratch varnish; advantageously, this varnish has hydroxyl groups, aliphatic CH groups, ester groups, and siloxane groups without methyl groups. This material makes it possible to produce optical pieces, in particular sunglasses, particularly solar glasses, as well as eyeshades for helmets or masks.
