ABSTRACT:
The present invention provides a transparent functional film comprising a transparent plastic substrate film and a hard coat layer provided thereon, wherein functional ultrafine particles are present in a highly localized form, thereby enabling the functional ultrafine particles to effectively exhibit their function and, at the same time, the hard coat layer to have a good adhesion to the functional ultrafine particle layer; and also an antireflection film and processes for producing the transparent functional film and the antireflection film.
A functional ultrafine particle layer 2 is formed on a release film 1. Separately, a resin composition for a hard coat layer is coated on a transparent plastic substrate film 3. The coated release film is laminated by press bonding to the coated transparent plastic substrate film so that the functional ultrafine particle layer 2 faces the resin composition coating, thereby causing part of the functional ultrafine particles 5 to be embedded in the resin composition coating for a hard coat layer. The resultant laminate is cured, and the release film 1 is then peeled off. In the resultant transparent functional film, the functional ultrafine particle layer 2 is partly embedded in and fixed to the hard coat layer 4, and the functional ultrafine particles 5 are localized in the hard coat layer 4 on its surface side.
