Abstract:
1. An antireflective coating exhibiting improved alkali resistance, wherein said antireflective coating comprises: (1) a three-dimensional crosslinked structure containing fluorine atoms and silicon atoms, said three-dimensional crosslinked structure comprising Si—O—Si linkages and Si—C (2) perfluoroalkyl groups having the following structure: wherein a is equal to 4, 6, 8, 10 or 12, and said perfluoroalkyl groups account for 90 to 100 mol % of all monovalent organic substituent groups attached to said silicon atoms of said three-dimensional crosslinked structure; and (3) a single end-capped diorganopolysiloxane chain containing silicon atoms, wherein a molar ratio of the total number of fluorine atoms to the total number of silicon atoms within the antireflective coating is from 8.0 to 10.0, whereby said antireflective coating is formed as an outermost layer on a transparent synthetic resinous substrate.
