Document Type and Number:
Japanese Patent JPWO2022118723
Kind Code:
A1
Abstract:
The present invention provides an epoxy resin which contains: a glycidyl etherified product (E1) of a biphenolic compound (P1); and a glycidyl etherified product (E2) of a phenolic hydroxyl group-containing resin (P2) that uses, as reactant materials, a dihydroxyarene compound (α) and an aralkylating agent (β) that is represented by general formula (1-1) or (1-2). (In general formulae (1-1) and (1-2), X represents a halogen atom, a hydroxyl group or an alkoxy group; each R1 independently represents a hydrogen atom or an alkyl group having from 1 to 4 carbon atoms; each R2 independently represents a hydrogen atom or a methyl group; and Ar1 represents a phenyl group, a naphthyl group, or a structural moiety that has one or more halogen atoms, one or more aliphatic hydrocarbon groups, or one or more alkoxy groups on one of these aromatic nuclei.)
