摘要：The present invention is a laminate which comprises: a) a plastic substrate having a surface; b) an adhesion promoter layer which is a first plasma polymerized organosilicon compound deposited on the surface of the substrate in the substantial absence of oxygen; and c) a protective coating layer which is a second plasma polymerized organosilicon compound deposited on the surface of the adhesion layer at a power density from about 106 J/kg to about 108 J/kg, and in the presence of a sufficient stoichiometric excess of oxygen to form a silicon polymer of SiO1.8-2.4 C0.3-1.0 and H0.7-4.0. The coating layer provides abrasion and solvent resistance for the substrate, and the adhesion promoter prevents the coating layer from peeling off the substrate. The coated plastic substrate can be used in liquid crystal display devices as an alternative to glass.
