<p>A novel polyhydric phenol represented by the general formula: <CHEM> wherein R<5> to R<8> independently represent hydrogen, an alkyl or cycloalkyl group having 1 to 9 carbon atoms, or halogen, and X represents hydrogen, an alkyl group having 1 to 9 carbon atoms, or an aryl group, and n represents an average number of repeating units of 0.1 to 10. With the above polyhydric phenol as starting material, there is provided an epoxy resin represented by the general formula: <CHEM> wherein R<5> to R<8>, X and n are as defined above. There is provided an epoxy resin composition comprising the above epoxy resin and a curing agent. The cured products from the above epoxy resin are excellent in less hygroscopicity and have a balance between thermal resistance and curing performance.</p> |
