Abstract: A multilayer magnetic sheet is described which comprises a plurality of stacked magnetic component layers separated by first electrically insulating layers. Each of the plurality of magnetic component layers comprises a plurality of isolated magnetic sublayers having a magnetic layer thickness of less than one micron. The multilayer magnetic sheet has a magnetic fraction between about 5% and about 80%; a total magnetic thickness of greater than or equal to 5 microns; and a relative composite permeability of greater than about 20.

Abstract: 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.

Abstract: A patterned article includes a carrier layer having a microstructured first major surface and an opposing second major surface. The first major surface includes pluralities of upper and lower edges spaced apart along a thickness direction of the carrier layer and defining respective upper and lower portions of the first major surface. The lower portion is disposed between the upper portion and the second major surface. The article includes a first functional layer disposed on the lower, but not the upper portion of the first major surface. The first functional layer includes at least one first micro-cut inorganic layer including a plurality of cut edges substantially coextensive with the plurality of lower edges. A method of making the patterned article is provided. Articles that can be made by transferring a functional layer from the patterned article are provided.

Abstract: A transfer article includes an acrylate layer releasable from a release layer including a metal layer, a metal oxide layer, or a doped semiconductor layer at a release value of from 2 to 50 grams/inch (0.8 to 20 g/cm). A functional layer overlies the acrylate layer, wherein the functional layer includes at least one layer of a functional material selected to provide at least one of a therapeutic, aesthetic or cosmetic benefit on a dental appliance in a mouth of a patient, and wherein the transfer article has a thickness of less than 3 micrometers. A pattern of a transfer material is on a major surface of the functional layer, wherein the transfer material includes an adhesion modifying material chosen from release materials and adhesives.

Abstract: An optical system includes an extended illumination source configured to emit light from an extended emission surface thereof and a light redirecting layer disposed on the extended emission surface. The light redirecting layer has a structured major surface that includes a regular array of light redirecting structures, each light redirecting structure including a plurality of facets; and a plurality of discrete spaced apart window segments. The optical system includes a plurality of reflective segments where each reflective segment is disposed on a corresponding window segment. For substantially normally incident light, each reflective segment has a total: average optical reflectance of at least 30% in a visible wavelength range extending from about 420 nm to about 650 nm; and optical transmittance of at least 10% for at least one infrared wavelength in an infrared wavelength range extending from about 800 nm to about 1200 nm.

Abstract: A retroreflective article including a binder layer and a plurality of retroreflective elements. Each retroreflective element includes a transparent microsphere partially embedded in the binder layer. At least some of the retroreflective elements include a first layer that is disposed between the transparent microsphere and the binder layer and a second layer that is disposed between the transparent microsphere and the binder layer. At least one of the first layer and the second layer is a reflective layer; and, the first reflective layer and the second reflective layer differ in reflectivity. For at least some of the retroreflective elements, at least a portion of the second reflective layer is positioned in-parallel to the first reflective layer.
