Abstract: A partially esterified epoxy resin and an epoxy resin composition applied with the same, and a method for preparing the composition are provided. The preparation method includes the following steps. A bifunctional epoxy resin and an anhydride are mixed and heated, wherein the number of equivalent moles of the bifunctional epoxy resin is greater than that of the anhydride, to form a partially esterified epoxy resin. A curing agent is mixed into the partially esterified epoxy resin to form a mixed solution. The mixed solution is cured to form the partially esterified epoxy resin composition.
