Abstract
To provide an antifouling film-coated substrate, which has a fluorinated organic silicon compound coating film and which is excellent in the antifouling properties as it has water repellency, oil repellency, etc. and also excellent in the abrasion resistance so that deterioration in the antifouling properties is prevented against repeated wiping operations. The antifouling film-coated substrate 3 comprises a transparent substrate 1 having a film-forming surface 1a exposed to at least a moisture-containing atmosphere, and a fluorinated organic silicon compound coating film 2 formed on the film-forming surface 1a of the transparent substrate 1 by a dry-mode method.
Claims11
A process for producing an antifouling film-coated substrate comprising a transparent substrate and a fluorinated organic silicon compound coating film formed thereon, which comprises
- an atmosphere treatment step of exposing a film-forming surface of the transparent substrate on which the fluorinated organic silicon compound coating film is to be formed, to at least a moisture-containing atmosphere, and
- a film-forming step of applying and reacting, after the atmosphere treatment step, a composition containing a fluorinated hydrolysable silicon compound on the film-forming surface to form the fluorinated organic silicon compound coating film.
