Adamantyl group-containing epoxy-modified (meth)acrylate and resin composition containing the same
View Patent ↗The present invention provides an adamantyl group containing epoxy-modified (meth)acrylate and a resin composition containing it which are imparted by transparency, optical characteristics such as (durable) light resistance and the like, heat-resistance, and good mechanical properties. For example, they are an adamantyl group containing epoxy-modified (meth)acrylate having the following general formula (I) and a composition containing it. In the formula, R 1 represents a hydrogen atom or a methyl group, and R 2 represents a halogen atom or an aliphatic hydrocarbon group which may contain a hetero atom. Plural R 2 may be the same or different, and m represents an integer of 0 to 4 and n represents an integer of 0 or more.
