Abstract:
A multilayer article comprising:a substrate; a first layer comprising an ultraviolet radiation absorbing material, the ultraviolet radiation absorbing material comprising at least one polybenzoylresorcinol, and a partial condensate of a diorganodiorganooxysilane having the formula R2Si(ORâ€²)2 or an organotriorganooxysilane having the formula RSi(ORâ€²)3, or both, where R is independently selected from the group consisting of alkyl groups containing about 1-3 carbon atoms, aromatic groups containing about 6-13 carbon atoms, vinyl radical, 3,3,3-trifluoropropyl radical, gamma-glycidoxypropyl radical and gamma-methacryloxypropyl radical, and Râ€² is independently selected from the group consisting of alkyl groups containing about 1-8 carbon atoms, aromatic groups containing about 6-20 carbon atoms, and hydrogen; and a second layer comprising a plasma polymerized organosilicon, the second layer being deposited at a power level of 106-108 J/Kg in the presence of excess oxygen.
