(57) [Problem] To provide a phenol-amino condensation resin excellent in heat resistance, water resistance, flame retardancy, strength, curability and the like, and an epoxy resin composition using the same. SOLUTION: This is a condensate comprising a phenol derivative, an aldehyde and a triazine derivative, wherein the ratio Mw / Mn of the number average molecular weight (Mn) to the weight average molecular weight (Mw) is 1.6 to 15. And an epoxy resin composition containing the phenol / amino condensation resin in an epoxy resin. |
