Antireflective coating, coating composition, and antireflective coated article |
摘要 |
An antireflective coating having improved alkali resistance is formed on a transparent substrate of synthetic resin as an outermost layer and has a three-dimensional crosslinked structure containing F and Si atoms. The crosslinked structure is composed of Si-O-Si and Si-C<SUB>2</SUB>H<SUB>4</SUB>-(CF<SUB>2</SUB>)<SUB>n</SUB>-C<SUB>2</SUB>H<SUB>4</SUB>-Si linkages wherein n is 4 or 6; the molar ratio of F atoms to Si atoms is from 8.0 to 10.0; and perfluoroalkyl groups account for 90 to 100 mol % of all monovalent organic substituent groups attached to silicon atoms. The antireflective coating can exhibit such alkali resistance that when a droplet of a 1 wt % NaOH aqueous solution is rested on the antireflective coating for 30 minutes and then wiped off, the appearance of the coating is kept unchanged from the initial appearance.
