PURPOSE:To provide the subject polymerized film composed of a polymerized fluoromonomer film having an oxygen/carbon atomic ratio falling within a specific range, having excellent barrierness to moisture transmission, faint color and excellent transparency and useful for the surface-protection of magneto- optical disk, etc. CONSTITUTION:The objective polymerized film has an O/C atomic ratio (ratio of oxygen to carbon in the polymerized film of fluoromonomer) of 0.0175-0.05 (preferably 0.03-0.04) and preferably has an F/C ratio of >=1.15. |
