摘要:
An optical member and process for making it including an optical substrate, a multilayered antireflection film provided on the optical substrate, and a water-repellent layer provided on an outermost layer of the multilayered antireflection film, wherein the outermost layer of the multilayered antireflection film is a layer containing, as a major component, silicon dioxide; and the water-repellent layer includes a first layer containing, as major components, a fluorine-substituted alkyl group-containing organosilicon compound and a silicon-free perfluoropolyether and a second layer provided on the first layer and which is in direct contact therewith, which contains, as a major component, a silicon-free perfluoropolyether.
