PURPOSE:To provide the titled compsn. which is excellent in heat resistance, adhesion and ability of wetting adherends and has a low refractive index, consisting of a specified polyfluoroepoxy resin, butyl glycidyl ether and/or phenyl glycidyl ether and a hardener. CONSTITUTION:0.8-1 equivalent (per equivalent of the epoxy group in component A) of a hardener (e.g. triethylenetetramine) and optionally 0.5-2pts.wt. curing accelerator (e.g. benzyldimethylamine) are blended with an epoxy resin compsn. having a viscosity of 200-50,000cp, consisting of 100pts.wt. polyfluoroepoxy resin (A) of the formula (wherein n is 0 or a positive number) and 5- 25pts.wt. butyl glycidyl ether and/or phenyl glycidyl ether (B). EFFECT:A cured article excellently matching with optical fiber, optical lens, etc. can be obtd.
