Abstract
An olefin polymer and a curable resin composition which can form cure coatings with excellent transparency, low reflectance, and high scratch resistance, an antireflection film exhibiting excellent transparency, low reflectance, and high scratch resistance are disclosed. The olefin polymer comprises a polysiloxane segment in the main chain, has 30 wt % or more fluorine content, and has a polystyrene-reduced number average molecular weight of 5,000 or more. The curable resin composition comprises the olefin polymer. The antireflection film is made from the cured product of the curable resin composition.
