摘要:
A UV-curable composition for optical discs contains a fluorine-containing UV-curable resin having a poly(perfluoroalkylene ether) chain and a UV-curable group. The fluorine-containing UV-curable resin exhibits good compatibility with the composition and satisfactorily localizes in and near a surface of a coating film. Thus, the composition can be used to form an outermost layer of an optical disc such that the droplet size of grease such as that constituting fingerprints adhering to the outermost layer is reduced and scattering of light having a short oscillation wavelength passing through the outermost layer is suppressed. Accordingly, an optical disc on and from which signals can be satisfactorily recorded and read is formed.
