摘要：
A hard coating composition comprising an epoxy group-containing organic silicon compound and inorganic submicron particles such as silica sol is curable with a minimal amount of an antimony compound as the curing catalyst. The composition is thus stable during shelf storage and can be cured to a plastic optical article as a mar resistant hard coating film.
