<p>The objective of the present invention lies in offering optical articles to which contaminants do not readily adhere and from which contaminants are readily removed. The objective of the present invention is realized by means of optical articles characterized in that they have an organosilicon compound layer at the surface, and the contact angle of artificial fingerprint liquid at said surface is at least 60E and, furthermore, the sliding angle of the artificial fingerprint liquid is no more than 30E. Again, the objective of the invention is realized by a method of producing optical articles characterized in that, in a method in which an organosilicon compound is evaporated within a vacuum tank and coated onto the surface of an optical article, said organosilicon compound is subjected beforehand to polycondensation. Furthermore, the objective of the present invention is realized by means of specified organosilicon compounds. The optical articles of the present invention can be favourably used for various types of display image screens, various types of display device display screens, optical filters, spectacle lenses, optical lenses, lighting appliances, exhibition cases or display windows, picture mounts, window glass and other such optical articles, or optical articles which are used attached thereto.</p> |
