Zusammenfassung:	PURPOSE:To provide the optical disk which has an excellent antistatic property and improved flawing resistance by coating the photoirradiated surface of the optical disk with the cured and coated film of a curable resin compsn. CONSTITUTION:This optical disk is constituted by coating the photoirradiated surface of the optical disk with the cured and coated film of the curable resin compsn. contg. (A) 3 to 40wt.% mono(meth)acrylate of the oligoethylene oxide and oligopropylene oxide of formula CH2=CR CO(OCH2CHR )nOH (R , R denote a hydrogen atom or methyl group; (n) denotes integer from 4 to 6), (B) 40 to 80wt.% dipentaerithritol hexa(meth)acrylate or the caprolacton modified matter thereof, (C) 0 to 40wt.% of polymerizable diluent exclusive of the components (A), (B) at need, (D) an anionic surfactant at 0.01 to 10wt.% of the total weight of the components (A), (B) and (C), and (E) a photopolymn. initiator at 1 to 10wt.% of the total weight of the components (A), (B) and (C).
