Abstract
The invention describes a composite material comprising a substrate having, on at least one of its faces, an impact-resistant primer layer and at least one abrasion-resistant coating layer deposited on the primer layer. The primer layer is obtained by applying, to the surface to be treated, a latex consisting of structured particles of polymers having a range with a “soft” character (Tg<20° C.) and another range with a “hard” character (Tg>50° C.).The composite material described is intended for various industries, such as the automobile industry (windows, headlights, etc.), the building industry (windows) or the sanitaryware industry.
