A light control film is described comprising a light input surface and alight output surface opposite the light input surface; alternating transmissive regions and absorptive regions disposed between the light input surface and the light output surface, wherein the absorptive regions comprise light-absorbing or light-reflecting particles and a dried aqueous dispersion of an organic polymer. The light control film can have improved on-axis transmission in combination with sufficiently high sheet resistance such that the film does not detract from the responsiveness of a touch screen of an electronic device. Also described is a coated article and method of making.

Coated substrate comprising electrically conductive particles and dried aqueous dispersion of organic polymer

A polarizer including an oriented polymeric first layer is described. The oriented polymeric first layer is preparable from a mixture of polyvinyl alcohol and crosslinker where the crosslinker is included in the mixture at 5 to 40 percent by weight based on the total weight of the polyvinyl alcohol and crosslinker. The oriented polymeric first layer is a substantially uniaxially drawn layer, in that for U=(1/MDDR&#x2212;1)/(TDDR&#x2212;1), U is at least 0.85, with MDDR being a machine direction draw ratio and TDDR being a transverse direction draw ratio.

Polarizer

A sheet comprising: (1) a core member comprising one or more layers and having a first major surface and (2) a slip control layer disposed on at least a portion of the first major surface, wherein the slip control layer comprises: (i) a footing layer disposed on at least a portion of the first major surface of the core member, (ii) a binder layer disposed on the footing layer, and (iii) an array of particles disposed in the binder layer and footing layer and protruding therefrom, wherein the average diameter of the particles is greater than the combined thickness of the foot layer and binder layer. A process for making such a sheet comprising: (1) providing a core member; (2) forming a footing layer on at least a portion of the first major surface of the core member, wherein the footing layer is viscoelastic and has a Tthat is lower than either the Tor the Tof the polymer at the first major surface of the core member; (3) applying a binder layer composition comprising a film forming polymer and particles to the surface of the footing layer; then (4) tentering the assembly under sufficient heat to soften the footing layer such that the particles sink into the footing layer, wherein the average diameter of the particles is greater than the combined thickness of the footing layer and binder layer.

Articles with binder-deficient slip coating and method for making same

A textured film, a process for manufacture of the textured film, and a light management stack, a backlight, and a display using the textured film are described. The textured film and process for manufacture thereof, include processes in which the surface texture of the optical film is controlled by incorporation of a patterned coating. The surface texture of a polymeric film, such as a polymeric optical film, is controlled by incorporation of the coating, that can fracture or deform upon stretching the film.

Textured film and process for manufacture

An antistatic article having an antistatic layer disposed on a substrate is disclosed herein. The antistatic layer is formed from a cationic copolymer, a non-cationic (meth)acrylic polymer, and a crosslinking agent. The cationic copolymer consists essentially of a cationic monomer, a hydrophobic monomer, a crosslinkable monomer, and an optional nitrogen-containing monomer. The substrate may comprise an optical film such as a multilayer optical film. Methods for making the antistatic article and display devices containing the antistatic article are also disclosed.

A textured film, a process for manufacture of the textured film, and a light management stack, a backlight, and a display using the textured film are described. Generally, the surface texture of a polymeric film, such as a polymeric optical film, is controlled by incorporation of a fracturable coating that fractures upon stretching the film.

Textured film and process for manufacture thereof

Disclosed herein is an optical article including a multilayer optical film and a primer layer disposed on the multilayer optical film. The primer layer consists essentially of a sulfopolyester and a crosslinker. The multilayer optical film may be a reflective film, a polarizer film, a reflective polarizer film, a diffuse blend reflective polarizer film, a diffuser film, a brightness enhancing film, a turning film, a mirror film, or a combination thereof. A microstructured or unstructured optical layer may be disposed on the primer layer opposite the multilayer optical film. Also disclosed herein is a method of making the optical article. Also disclosed herein is a display device including the optical article.

A soil-resistant spin finish composition based on select derivitized polyethers is provided that can be applied to a fiber at the earliest stages of spinning, can remain on the fiber through the entire manufacturing process, and can be left on the fiber in the final article of commerce. The spin finish composition provides excellent fiber lubrication during high-speed spin processing, yet is sufficiently soil resistant to negate the need for scouring the final fiber construction, even absent the presence of additional coatings or agents.

Soil-resistant spin finish compositions

A low melting, high solids spin finish composition is provided that can be readily applied to synthetic fibers during the fiber-making process. The spin finish solids, which make up at least about 70% by weight of the spin finish composition, comprise nonionic hydrocarbon surfactant components, such as polyoxyalkylenes, which have a <HLB> value of from about 2 to 13 and a melting point within the range of about 25&deg; C. to about 140&deg; C. In some embodiments, the spin finish composition also includes select fluorochemicals.

Process of drawing fibers

A high solids spin finish composition is provided which includes a nonionic hydrocarbon surfactant and which has a <FLB> value of less than 11 and a <HLB> value within the range of about 2 to 13.
