Abstract: Certain patternable reflective films are used as masks to make other patterned articles, and one or more initial masks can be used to pattern the patternable reflective films. An exemplary patternable reflective film has an absorption characteristic suitable to, upon exposure to a radiant beam, absorptively heat a portion of the film by an amount sufficient to change a first reflective characteristic to a different second reflective characteristic. The change from the first to the second reflective characteristic is attributable to a change in birefringence of one or more layers or materials of the patternable film. In a related article, a mask is attached to such a patternable reflective film. The mask may have opaque portions and light-transmissive portions. Further, the mask may have light-transmissive portions with structures such as focusing elements and/or prismatic elements.

Abstract: A reflective film includes interior layers that selectively reflect light by constructive or destructive interference, the layers extending from a first to a second zone of the film. In the first zone the layers provide a first reflective polarizer characteristic, and in a second zone the layers provide a substantially different reflective polarizer characteristic. The second zone is characterized by at least some of the layers having a reduced birefringence relative to their birefringence in the first zone. In some cases the first reflective polarizer characteristic may have a pass axis that is substantially orthogonal to that of the second reflective polarizer characteristic. The film may have substantially the same thickness in the first and second zones, or a substantially reduced thickness in the second zone relative to the first zone.

Abstract: A patterned article includes a unitary polymeric layer and a plurality of electrically conductive elements embedded at least partially in the unitary polymeric layer. Each electrically conductive element includes a conductive seed layer having a top major surface and an opposite bottom major surface in direct contact with the unitary polymeric layer, and includes a metallic body disposed on the top major surface of the conductive seed layer. The metallic body has a bottom major surface and at least one sidewall. The bottom major surface contacts the conductive seed layer. Each sidewall is in direct contact with the unitary polymeric layer and extends from the bottom major surface of the metallic body toward or to, but not past, a top major surface of the unitary polymeric layer. The conductive elements may be electrically isolated from one another. Processes for making the patterned article are described.

Abstract: An optical assembly including an optical element insert molded directly onto an optical stack is provided. The optical stack includes an optical film and may include a liner with the optical film being disposed between the optical element and the liner. The liner, if included, is removable from the optical film without substantial damage to the optical film. An outermost layer of the optical film may be diffusion bonded to a major surface of the optical element. The optical film includes a protective coating having an average thickness of no more than 30 micrometers. The protective coating includes an at least partially cured composition. The composition includes 70 to 96 weight percent of urethane (meth)acrylate compound having an average (meth)acrylate functionality of 2 to 9.5, and 2 to 20 weight percent of (meth)acrylate monomer having a (meth)acrylate functionality of 1 to 2.

Abstract: A method of making an infrared-reflecting optically transparent assembly comprises: coating a curable composition onto a major surface of an optically transparent thermoplastic polymer film; at least partially curing the curable composition, which may be optionally at least partially dried, to provide a thermoformable composite film; and laminating the thermoformable composite film to an infrared-reflecting multilayer optical film to provide the infrared-reflecting optically transparent assembly. The curable composition comprises urethane (meth)acrylate compound, (meth)acrylate monomer, and silicone (meth)acrylate. The infrared-reflecting optically transparent assembly and methods of including it in an infrared-reflecting lens assembly are also disclosed.

Abstract: Wavelength-selective films are visibly apparent under the selective wavelength. Wavelength-selective films typically reflect off axis the selected wavelength and therefore can provide high-contrast against a background when applied in a pattern on a substrate. However, it is difficult to apply unique patterned embedded images from film. Disclosed is a cost-effective method and construction of a patterned wavelength-selective image to a substrate. In the disclosed wavelength-selective image, wavelength-selective film particles are applied to an adhesive pattern to create the wavelength-selective image.
