Optical film coating
A low fringing film coating includes a transparent polymeric layer having a surface, and a plurality of projections extending away from the surface. The projections have a mean height of 0.05 to 1 m and a mean distance between projections of 0.5 to 2 mm. The coating can be produced by coating a poly...

| Zusammenfassung: | A low fringing film coating includes a transparent polymeric layer having a surface, and a plurality of projections extending away from the surface. The projections have a mean height of 0.05 to 1 m and a mean distance between projections of 0.5 to 2 mm. The coating can be produced by coating a polymeric composition onto a substrate. The polymeric composition includes a polymeric material, a good solvent for the polymeric material and a poor solvent or the polymeric material. The solvents are at least partially evaporated to form a low fringing transparent polymeric layer. |
