An antireflection film and method of making same includes a substrate having a first surface and a second surface, an inorganic layer deposited on the first surface of the substrate, and an optically active polymer layer formed by curing a curable composition in situ on the inorganic layer, the polymer layer having a refractive index not greater than about 1.53 over the wavelength range of 400 nm to 700 nm and a thickness of from about 20 nm to about 200 nm, and an adhesive layer deposited on the second surface of the substrate.

Removable antireflection film

The present invention provides pressure-sensitive adhesives having a refractive index of at least 1.48. The pressure-sensitive adhesives comprise at least one monomer containing a substituted or an unsubstituted aromatic moiety.

High refractive index pressure-sensitive adhesives

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

Optical product having a high refractive index microreplication resin

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.

Antisoiling hardcoat

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.

High refractive index microreplication resin from naphthyloxyalkylmethacrylates or naphthyloxyacrylates polymers

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.

Composition and structures made therefrom

Described are a polymerizable composition comprising an alkyl-substituted brominated phenolic ester (meth)acrylate monomer having an index of refraction of at least 1.50, and, polymeric materials derived therefrom.

High refractive index chemical composition and polymers and polymeric material derived therefrom

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.

Patterned article having alternating hydrophilic and hydrophobic surface regions

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.

Brightness enhancement article

Described are coatings, composite structures containing coatings, and compositions for preparing and methods of preparing coatings and composite structures, wherein the compositions comprise inorganic oxide particles and polymerizable brominated compounds, and coatings comprise inorganic oxide particles and a brominated polymer.
