OPTICAL ARTICLE, METHOD FOR PREPARING OPTICAL ARTICLE AND ORGANIC SILICON COMPOUND

摘要

An optical article which has an organic silicon compound layer on the surface thereof, characterized as exhibiting a contact angle for an artificial finger print liquid on said surface of 60 DEG or more and a falling angle for the artificial finger print liquid of 30 DEG or less; a method for coating an optical article with an organic silicon compound which involves vaporizing the compound in a vacuum vessel, characterized in that the organic silicon compound has been subjected to condensation polymerization in advance: and a specific organic silicon compound for use in the optical article. The optical article has advantages in that it is less susceptible to staining and is easy to remove stains. The optical article can be suitably used in applications such as image planes of various displays, plains for display in various display devices, optical filters, eyeglass lenses, optical lenses, luminaries, cases or show windows for exhibition, frames for picture, windowpanes and the like; and also for optical goods attached to the items described above.
