Transparent functional membrane containing functional ultrafine particles, transparent functional film, and process for producing the same

摘要

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 a process for producing the transparent functional film. A functional ultrafine particle layer (2) is formed on a release film (1). Separately, a resin composition for a hard coat layer (4) 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 (4). 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.
