PURPOSE:To obtain the title composition suitable for an adhesive of optical disk, photo-setting by active energy such as ultraviolet light, etc., having excellent initial adhesiveness, by blending an epoxy resin with a compound selected from sulfonium salt, etc. CONSTITUTION:(A) 100 pts.wt. aliphatic or alicyclic epoxy resin (e.g., bisphenol A) is blended with (B) 15-35 pts.wt. compound selected from the group of a sulfonium salt (e.g., triarylsulfonium salt) and a cyclopentadienyliron compound (e.g., cyclopentadienylisopropylphenyliron salt), (C) 1-10 pts.wt. compound selected from the group of (meta)acrylate and oligomers thereof and (D) 1-10 pts.wt. organic peroxide (e.g., benzoylperoxide).
