PURPOSE:To obtain a composition useful for material for base plate of optical disk having excellent heat resistance and optical transmission, consisting of bifunctional (meth)acrylate, monofunctional (meth)acrylate, fluorine-base monofunctional acrylate and radical polymerization initiator. CONSTITUTION:The aimed composition is composed of bifunctional, (meth) acrylate expressed by formula I (R1 is H or CR3) {e.g., bis(oxymethyl) tricyclo[5.2.1.0<2>, <6>]decane di(meth)acrylate}, monofunctional (meth)acrylate expressed by formula II (R2 is H or CH3) {e.g., tricyclo[5.2.1.0<2>, <6>]decane (meth) acrylate}, fluoride-base monofunctional acrylate (e.g., hexafluoroisopropylacrylate) and radical polymerization initiator (e.g., benzoyl peroxide). composition. |
