Abstract
This invention provides polymerizable silica sols in which at least one monomer containing double bond is used as its dispersion medium, especially a silica sol in which the monomer containing double bond is a monomer containing double bond and OH group or is a monomer having an adamantane structure. This invention also provides compositions which comprise these silica sols as composing elements, cured resins that are obtained by polymerizing these silica sols alone or together with other copolymerizable components, and new adamantane derivatives for use in these silica sols.
