The present invention concerns antireflective films comprising a high refractive index layer () and low refractive index layer () disposed on the high refractive index layer. The antireflective films have a microstructured surface () that can be derived from a microreplicated tool.

Antireflective films comprising microstructured surface

Light redirecting film is disclosed. The light redirecting film includes a first major surface that includes a plurality of first microstructures that extend along a first direction. The light redirecting film also includes a second major surface that is opposite to the first major surface and includes a plurality of second microstructures. The second major surface has an optical haze that is not greater than about 3% and an optical clarity that is not greater than about 85%. The light redirecting film has an average effective transmission that is not less than about 1.75.

Methods of forming patterned coatings are disclosed. The methods include the steps of disposing a composition onto a substrate to form a liquid coating on the substrate and providing or removing energy through a first pattern of areas on the coated film to form a morphologically patterned coating, the morphological pattern corresponding to the first pattern of areas.
