    Abstract: Article comprising a first, microstructured layer comprising a first material, and having first and second opposed major surfaces, the first major surface being a microstructured surface, and the microstructured surface having peaks and valleys, wherein the peaks are microstructural features each having a height defined by the distance between the peak of the respective microstructural feature and an adjacent valley; and a second layer comprising at least one of a crosslinkable or crosslinked composition, wherein at least a portion of the second major surface of the second layer is directly attached to at least a portion of the first major surface of the first, microstructured layer. Articles described herein are useful, for example, for optical film applications. For example. An article including a regular prismatic microstructured pattern can act as a totally internal reflecting film for use as a brightness enhancement film; an article including a corner-cube prismatic microstructured pattern can act as a retroreflecting film or element for use as reflecting film when combined with a back reflector; and an article including a prismatic microstructured pattern can act as an optical turning film or element for use in an optical display.

    Abstract: The process includes applying a first composition on at least the portion of a siliceous substrate and subsequently applying a second composition on at least a portion of the first composition. The first composition includes an amine-reactive organosilane compound that is at least partially hydrolyzed. The second coating composition includes at least one of an amino-functional silane or cyclic azasilane and a condensation-curable polyorganosiloxane having divalent units represented by formula (I). The use of the first composition to improve the durability of the second composition, a kit including the first composition and the second composition, and a coated article made by the process are also described.

    Abstract: There is provided an article comprising at least a first surface having a fluorine-containing polymeric binder resin layer and a plurality of microspheres partially embedded in a first major surface of the binder resin layer and adhered thereto; wherein the fluorine-containing polymer is derived in part from at least one partially fluorinated, or non-fluorinated, monomer; and wherein the article exhibits a stain resistance to yellow mustard at elevated temperature and humidity as measured by the change in b* of less than 50. There are also provided such articles wherein the fluorine-containing polymer is derived in part from at least one partially fluorinated, or non-fluorinated, monomer; and wherein the fluorine content along the polymeric backbone of the fluorine-containing polymer is from about 27% to 72% by weight. There are also provided such articles wherein the article is a thermoformable article exhibiting chemical resistance according to ASTM D5402 - 06.
