Abstract: A durable optical film or element includes a polymerized structure having a microstructured surface and a plurality of surface modified colloidal nanoparticles of silica, zirconia, or mixtures thereof. Display devices including the durable microstructured film are also described.

Abstract: Polymerizable compositions comprising nanopartilces particularly useful for brightness enhancing films.

Abstract: A durable optical film includes a polymerized optical film structure having a microstructured surface and a scratch contrast ratio value in a range of 1.0 to 1.65 or 1.0 to 1.15. These durable optical films can include a plurality of nanoparticles and a rounded prism apexes microstructure.

Abstract: Naphthalate polyester articles can be coated with polymerizable compositions containing a vinyl-functional crosslinkable film former, a large amount of benzotriazole and a copolymerizable monomer that solubilizes the benzotriazole. The cured compositions help protect the naphthalate polyester from UV exposure and other weathering effects.

Abstract: A method of making erasable article comprises: providing an electret film having first and second opposed major surfaces; applying a polymerizable precursor composition to at least a portion of the first major surface; polymerizing the polymerizable precursor composition to form a non-tacky crosslinked polymeric layer; and exposing the electret film and non-tacky crosslinked polymeric layer to a direct current corona discharge, wherein the second major surface is free of adhesive material. Erasable articles and kits containing them are also disclosed. Also disclosed are dry erase articles having a first coating layer coated onto a flexible substrate. The first coating composition has a hardness upon curing of greater than about 500 MPa and forms an ink receptive writing surface suitable for receiving dry erase marker ink. The first coating layer has minimal effect on the flexibility of the sheet.
