PURPOSE:To provide a photocurable resin composition which can rapidly undergo a photocuring reaction and can give a photocured molding of sufficient mechanical strengths and to provide an optical disc base molded therefrom. CONSTITUTION:A photocurable resin composition prepared by mixing a photocurable resin of the general formula: CH2=CR1C0O-R2-OOCR1C=CH2 (wherein R1 is hydrogen or methyl; and R2 is 2-10C alkylene, a bivalent branched hydrocarbon group or a bivalent branched hydrocarbon group interrupted by an ester bond) with 5-15wt.% thermoplastic resin soluble in the photocurable resin. |
