    • 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.
    • 公开了具有高粘附性,耐磨损的类金刚石硬质碳涂层的基本上光学透明的涂覆基材产品。 基底产品由聚合物基底,粘附介导性聚硅氧烷聚合物层,一个或多个中间层和金刚石状硬碳外层组成。 在本发明的另一个实施方案中,薄金属中间层设置在第一中间层和随后的夹层和/或类金刚石硬碳之间。 本发明还允许使用金刚石状硬碳作为高折射率层和作为低折射率层的中间层来制造粘附薄膜干涉层涂层(即四分之一波长叠层和抗反射涂层),或 ,或者,使用类金刚石硬碳作为低折射率层和中间层作为高折射率层。 本发明还公开了一种用于制造涂覆的基底产品的方法。 表现出优异的抗磨损和化学侵蚀性的基材产品对于诸如由聚碳酸酯,CR-39 TM或丙烯酸塑料制成的光学透镜和太阳眼镜片的商业塑料制品特别有用。
