Multilayer stacks that can be used as decorative microsphere articles. The decorative microsphere articles can be a durable and aesthetically pleasing substitute for anodized aluminum and other matte metallic surfaces. The decorative microsphere articles are durable and can have a bright diffused appearance of any desired color, for example white, gold, silver, red, or other colors, while being capable of being manufactured using a roll-to-roll process. The decorative microsphere articles can also provide novel optical effects than can change at different viewing angles, including, for example, changing color with view angle, changing sharpness or clarity of an image or icon with view angle, and the like, that may allow customers to differentiate their products.

A protective film includes a base layer and a wear layer, the wear layer comprising a UV cured hardcoat resin, and the UV cured hardcoat resin comprising surface modified silica nanoparticles. The protective film may comprise a pressure sensitive adhesive for adhesion to a floor. The protective film may be used, for example, as a protective floor finish.

Protective films and related methods

This disclosure provides (meth)acryloyl pressure-sensitive adhesive foams and foam articles having one or more of the following properties: small cells, uniform cell sizes, pressure sensitive adhesive compositions, compliance to irregular substrates and vibration damping, and shock absorbing properties.

(Meth)acryloyl pressure-sensitive foam adhesives

A low refractive index composition that forms a low refractive index layer on an optical display is formed having a co-crosslinked interpenetrating polymer network of a fluoropolymer phase and an acrylate phase. The fluoropolymer phase is preferably formed from fluoropolymers based on THV or FKM and having either a degree of unsaturation and/or containing a reactive cure site monomer in its polymer backbone. The acrylate phase includes a multifunctional acrylate crosslinker, and more preferably includes a perfluoropolyether acrylate crosslinker. The formed low refractive index layer has improved interfacial adhesion to other layers or substrates contained in the optical display. Further, the mechanical strength and scratch resistance of the either of above low refractive index compositions can be further enhanced through the incorporation of surface functionalized inorganic particle into the formed layer.

Low refractive index fluoropolymer compositions having improved coating and durability properties

The invention relates to articles such as protective films and displays having a fluorochemical surface layer comprising an antistatic agent and the reaction products of at least one fluoropolyether (meth)acryl compound and at least 50 wt-% of non-fluorinated crosslinking agent(s).

Article and comprising fluorochemical surface layer

The present invention includes optical coatings containing ultraviolet curable monomers employing a bromine substituted fluorene structure. The fluorene backbone of the monomers of the present invention may also be functionalized with one or more polymerizable or reactive functionalities, and most readily at the 9 position. Compositions of the present invention include the reactive bromosubstituted fluorenes combined with inorganic nanoparticles, particularly nanoparticles with reactive surface modifiers exhibiting polymerizable functionality. Reactive high index nanoparticles such as surface modified zirconia are contemplated.

High refractive index monomers for optical applications

The invention relates to display and protective articles having a fluorochemical surface layer, and methods of making such articles. The invention also relates to fluoropolyether acrylate compositions.

Article comprising fluorochemical surface layer

The present invention includes ultraviolet curable compositions preferably containing discrete, crystalline zirconia nanoparticles with reactive, or copolymerizable, surface modification, in a polymerizable monomer/oligomer resin mixture. It is believed that copolymerizable surface modification provides a functional group that enables the functionalized particle to co-polmerize with the reactive monomers, oligomers, and crosslinkers in the formulation. Relative to surface modification of the nanoparticles, acrylate functionality is preferred over methacrylate functionality. On the other hand, methacrylate functionality is preferred over non-reactive, or nonpolymerizable, functionality. As the nanocomposite cures, the resultant network is heavily crosslinked by selection of raw materials with substantial acrylate functionality.

Durable high index nanocomposites for AR coatings

A system for applying a fluid coating onto a substrate includes forming a fluid wetting line by introducing a stream of fluid onto a first side of the substrate along a laterally disposed fluid-web contact area. An electrical force is created on the fluid from an effective electrical field originating from a location on the second side of the substrate and at a location substantially at and downstream of the fluid contact area. The electrical field can be generated in a highly effective manner relative to the coating fluid by a sharply defined electrode on the second side of the substrate. Ultrasonics combined with electrostatic fields further enhances coating process conditions and coating uniformity.
