ABSTRACT:
A substantially optically transparent coated substrate product with a highly adherent, abrasion-resistant diamond-like hard carbon coating is disclosed. The substrate product is comprised of a polymeric substrate, an adhesion-mediating polysiloxane polymer layer, one or more intermediate layers and an outer layer of diamond-like hard carbon. In another embodiment of the invention a thin metallic interlayer is disposed between a first interlayer layer and subsequent interlayers and/or diamond-like hard carbon. The invention also allows for the production of adherent thin film interference layer coatings (i.e. quarter wavelength stacks and anti-reflection coatings) using diamond-like hard carbon as the high refractive index layer and the interlayer(s) as the low refractive index layer or, alternatively, using diamond-like hard carbon as the low refractive index layer and the interlayer(s) as the high refractive index layer. The invention further discloses a method for fabricating the coated substrate product. The substrate product, exhibiting excellent resistance to abrasion and chemical attack, is particularly useful for commercial plastic articles such as optical lenses and sunglass lenses made of polycarbonate, CR-39.RTM., or acrylic plastics.
