    • A modified phenolic resin which is toughened by phenoxy resin is disclosed. The modified phenolic resin is prepared by the following steps: mixing a phenoxy resin having a weight average molecular weight of 10,000-1,000,000 and phenol in a weight ratio of phenoxy resin:phenol=1.5:1-1:1 at an elevated temperature to form a glutinous mixture; mixing the glutinous mixture and an acid catalyst to obtain a viscous mixture having a relatively low viscosity compared to the glutinous mixture; mixing the viscose mixture and a resole type phenolic resin to form a modified phenolic resin, wherein the resole type phenolic resin has a solid content of 60--75 wt. % and a free aldehyde content of 5-10 wt. %, the amount of the acid catalyst mixed is 2-10 wt. %, and the amount of the phenoxy resin mixed is 3-25 wt. % based on the resole type phenolic resin.
