| abstract |
The present invention is an epoxy resin which is a reaction product of 1,2,3-trihydroxybenzene and an epihalohydrin, wherein the epoxy resin is derived from 1,2,3-trihydroxybenzene. An epoxy resin comprising a cyclic compound having a cyclic structure containing an adjacent oxygen atom as a constituent atom, wherein the content of the cyclic compound is 0.040 to 0.115 mol with respect to 100 g of the epoxy resin. Do. This epoxy resin has a possibility of being replaced as a bio-based polymer, and is liquid and excellent in heat resistance. |
