ABSTRACT:
An antireflection hard coating film of the invention comprises: a transparent plastic film substrate; and at least one hard coating layer of a cured coating layer and at least one antireflection layer that are formed in this order on at least one side of the transparent plastic film substrate, wherein a hard coating layer-forming material contains 100 parts by weight of a (meth)acrylate group-containing curable compound (A) and 0.01 to 3 parts by weight of a (meth)acrylate group-containing reactive silicone (B), and an antireflection layer-forming material contains a siloxane component-containing compound, at the interface between the hard coating layer and the antireflection layer being in direct contact with each other. The antireflection hard coating film has good adhesion between the hard coating layer and the antireflection layer, high hardness, and good scratch resistance without a reduction in antireflection properties.
