An epoxy resin composition comprising an epoxy resin, a hardener, a curing accelerator and a solvent, characterized in that said epoxy resin comprises as principal component an "epoxy resin a" which has a polydispersity coefficient, (Mw/Mn), lower than 2.5 and which is obtainable by reacting:
1. a polyglycidyl-etherified product (I), obtained by glycidyl-etherifying a polyfunctional phenolic compound, with
2. a difunctional epoxy resin (II), having the skeleton of at least one bisphenol compound selected from the group consisting of bisphenol A, bisphenol F and tetrabromobisphenol A, and with
3. at least one bisphenol compound (III), selected from the group consisting of bisphenol A, bisphenol F and tetrabromobisphenol A.

1. 通过缩水甘油醚化多官能团酚类化合物得到的缩水甘油醚化产品 (I); 2.
以至少一种双酚化合物为骨架的双官能环氧树脂(II),该双酚化合物选 自双酚 A、双酚 F 和四溴双酚 A,以及
从双酚 A、双酚 F 和四溴双酚 A 组中选出的至少一种双酚化合物 (III)。
