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 &#x3bc;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.

Optical film coating

Described are curable adhesives containing a polyacrylate component and an epoxy component, and that are preferably optically clear, as well as methods of using such adhesives and optical components and optical elements prepared from the adhesives.

An enhanced K-type polarizer includes a molecularly oriented sheet of polyvinylalcohol/polyvinylene block copolymer material having polyvinylene blocks formed by molecular dehydration of a sheet of polyvinylalcohol wherein the molecularly oriented sheet comprises light-polarizing molecules of polyvinylalcohol/polyvinylene block copolymer material varying in length, n, of conjugated repeating vinylene unit of the polyvinylene block, wherein an absorption concentration of each of the polyvinylene blocks in the range of n&equals;19 to 25 is not less than approximately 65% of the absorption concentration of any of the polyvinylene blocks in the range of n&equals;14 or 15, wherein the absorption concentration is determined by absorption of wavelengths from about 200 nm to about 700 nm by the polyvinylene blocks, and wherein the molecularly oriented sheet exhibits a photopic dichroic ratio, R , of at least approximately 75.
