An epoxy resin (a), having a polydispersity index of molecular weight distribution (ratio of Mw/Mn) lower than 3.0, obtainable by reacting:n A) a difunctional epoxy resin having the skeleton of at least one bisphenol compound selected from bisphenol A, bisphenol F and tetrabromobisphenol A, B) from 1 to 20% by weight based on the total weight of the components A, B and C, of a polyfunctional phenol compound, and C) at least one bisphenol compound selected from bisphenol A, bisphenol F, and tetrabromobisphenol A. |
