PROBLEM TO BE SOLVED: To provide a multilayer article and a making method by arc plasma deposition.SOLUTION: A method of forming a plurality of layers on an article includes steps of: generating a plasma by forming an arc between a cathode and an anode; injecting a first material comprising an organic compound into the plasma to deposit a first layer on the article; injecting a second material comprising an organometallic material into the plasma to form a second layer on the first layer; and injecting a third material comprising a silicon-containing organic compound into the plasma to deposit a third layer on the second layer. The invention also relates to an article comprising a substrate 110, an interlayer 120 disposed on the substrate, a second layer disposed on the interlayer and comprising an inorganic ultraviolet absorbing material, and a third layer disposed on the second layer and comprising an abrasion resistant material. The interlayer may comprise a polymerized organosilicon material or a polymerized hydrocarbon material. The second layer may comprise a metal oxide or zinc sulfide. The third layer may comprise an oxidized organosilicon material.
