Abstract: A polymerizable composition that includes a monomer of the formula wherein X is hydrogen or one or more of methyl, chlorine, bromine or iodine, R1 is a straight or branched alkyl linking group of 2 to 12 carbon atoms, R2 is hydrogen or methyl, and n is 1 to 3; and a monomer of the formula wherein X1 and X2 are each independently hydrogen or one or more of methyl, chlorine, bromine or iodine, and R2 is hydrogen or methyl is described having a high index of refraction and being suitable for use in forming an optical product.

Abstract: An antisoiling hardcoated film comprising a substantially transparent substrate, a hardcoat layer comprising inorganic oxide particles dispersed in a binder matrix, and an antisoiling layer comprising a perfluoropolyether. The antisoiling layer can be very thin, thus reducing the cost of the perfluoropolyether. The film has very good scratch, smudge and glare resistance and very good interlayer adhesion and durability. The film can be in the form of a single flexible substrate or a stack of such substrates. The film or stack can be sized to fit the display screen of an electronic display device such as a personal digital assistant or cell phone.

Abstract: Information display protectors for display devices having an information display area, comprising a stack of flexible substantially transparent sheets, the sheets having on one side thereof an adhesive layer and having on the other side thereof a hardcoat layer comprising inorganic oxide particles dispersed in a binder matrix and a low surface energy fluorinated compound, the stack being cut so that the sheets will fit the information display area. The low surface energy fluorinated compound can be part of the hardcoat layer or can be a separate layer atop the hardcoat layer. The protectors have very good scratch, smudge and glare resistance. The stack of protectors can be stored, for example, on a personal digital assistant or its cover or case.

Abstract: A non-halogenated composition having a high index of refraction, preferably greater than 1.55, comprising a vinyl monomer, such as methyl styrene. The cured composition is particularly suited for having a metal layer, such as silver, applied thereto. In one embodiment, the composition can be used to form a microreplicated prismatic structure. Preferably, the structure has two sides, where one side is substantially smooth and the other includes saw-tooth formations having tilted surfaces. A metal layer may be present on one or more sides of the prismatic substrate having the saw-tooth formations.

Abstract: An article is disclosed that has a patterned surface containing alternating hydrophobic and hydrophilic surface regions. The hydrophobic regions may be sufficiently narrow such that under dew conditions moisture accumulated on the hydrophobic region migrates to the hydrophilic region, thus preventing the accumulation of water droplets. In frost conditions, the hydrophobic region remains relatively frost-free, thus maintaining at least partial transparency of the surface. Inorganic oxide particles on the surfaces of the hydrophobic regions may provide abrasion resistance. A method for making the patterned surfaces is disclosed in which a treatment removes organic binder to expose inorganic oxide particles at the surface of the hydrophilic regions.

Abstract: A brightness enhancement article that includes: (a) a transparent, flexible substrate; (b) a first major surface having an array of prisms with blunted or rounded peaks characterized by a chord width, cross-sectional pitch width, and radius of curvature in which the chord width is equal to about 20-40% of the cross-sectional pitch width and the radius of curvature is equal to about 20-50% of the cross-sectional pitch width; and (c) a second major surface characterized by a plurality of light scattering protrusions. The article has a haze value between about 20-60% and a transmission value no greater than about 94% when measured under conditions in which the first surface has a substantially planar topography.
