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.
