Abstract: Films and articles are described comprising a microstructured surface having an array of peak structures and adjacent valleys. For improved cleanability, the valleys preferably have a maximum width ranging from 10 microns to 250 microns and the peak structures have a side wall angle greater than 10 degrees. The peak structures may comprise two or more facets such as in the case of a linear array of prisms or an array of cube-corners elements. The facets form continuous or semi-continuous surfaces in the same direction. The valleys typically lack intersecting walls. Also described are methods of making and methods of use. The microstructured surface of the article can be prepared by various microreplication techniques such as coating, injection molding, embossing, laser etching, extrusion, casting and curing a polymerizable resin; and bonding microstructured film to a surface or article with an adhesive.

Abstract: Wet-on-wet coating processes are provided to produce multilayer articles. First and second coating materials are sequentially applied on to a structured substrate surface to form a skin layer directly over the structured substrate surface and a bulk layer over the skin layer. The conformability of the skin layer can be adjusted to provide desired surface and bulk properties.

Abstract: Curable compositions include at least one fluoropolymer, at least one monofunctional (meth)acrylate, at least one difunctional (meth)acrylate, and at least one initiator. The curable composition, when cured, forms an optically-scattering layer including a matrix and phase separated microdomains. The matrix and the phase separated microdomains have different refractive indices, and the microdomains are on the order of or larger than the wavelengths of visible light.
