Document Type and Number:
WIPO Patent Application WO/2019/017013
Kind Code:
A1
Abstract:
The present invention provides an epoxy resin which is a reaction product of 1,2,3-trihydroxybenzene and epihalohydrin, the epoxy resin being characterized by including a cyclic compound having a cyclic structure containing, as a constitutive atom, two neighboring oxygen atoms derived from 1,2,3-trihydroxybenzene, wherein the content of said cyclic compound is 0.040-0.115 mol per 100g of the epoxy resin. This epoxy resin has a possibility of substitution as a bio-based polymer and excellent heat resistance as a liquid phase.
