The epoxy resin composition which modifies a crystalline epoxy resin and gives the hardened | cured material which has favorable hardening physical property is provided.n n n Equation (1):n n n n n n n n (Wherein R 1 and R 2 are each an alkyl group, an alkenyl group, an alkynyl group, an aryl group, an aralkyl group, a heterocyclic group, or a halogenated, aminated or nitrated derivative thereof) And a modified epoxy resin composition containing a compound B having a glycidyl group in a molecule. The compound A is preferably a compound in which one or more n-based glycidyl groups in the molecule (where n is an integer of 2 to 16) are substituted with a functional group of formula (1). The compound B is preferably a compound having n glycidyl groups in the molecule, where n is an integer of 2 to 16. |
