<P>PROBLEM TO BE SOLVED: To provide an optical film, including an antireflection function having high scuff resistance and chemical resistance even in the case of using transparent base material to which an ultraviolet ray absorber is added and transparent base material not transmitting an ultraviolet ray. <P>SOLUTION: This optical film satisfies the following expressions (I), (II) concerning the reaction rate of double bond of a composite layer including a hard coat layer 2 and an antireflection layer 3 formed by wet coating method. The expression (I) α, β>60, and the expression (II) α/β>0.95, wherein α, β are reaction rates calculated by [1-ä(quantity of double bond groups in cured composite layer)/(quantity of double bond groups in the uncured composite layer)}]×100, α is a reaction rate of the composite layer to 0.55 μm from the surface of the composite layer, and β is a reaction rate of the composite layer to 0.63 μm. <P>COPYRIGHT: (C)2010,JPO&INPIT |
