COATING COMPOSITION AND ANTIREFLECTION FILM

摘要

This coating composition comprises (A) a metal oxide that comprises (a1) a spherical metal oxide and (a2) a chain-shaped metal oxide having an aspect (length/breadth) ratio of 3 to 25 and (B) polymer emulsion particles. It is preferable that the coating composition further contains (C) a hydrolyzable silicon compound. Further, this antireflection film can be formed by applying the coating composition to a substrate and drying the resulting coating.
