Document Type and Number:
WIPO Patent Application WO/2001/071394
Kind Code:
A1
Abstract:
An antireflection product having on a substrate an optical thin film which is formed by removing columnar phases from a composite film consisting of many one-dimensionally grown columnar phases and matrix phases surrounding the former, and in which are formed many pores continuing from one surface to the other of the film, surrounded by walls consisting of the matrix phases, and one-dimensionally penetrating, characterized in that the refractive index of the optical thin film is lower than that of the substrate and between that of the matrix phases and one, whereby providing the antireflection product low in reflective index, high in film strength, and excellent in adhesiveness to the substrate; and a production method therefor.
