    Abstract: Provided is a surfacing film that includes a plurality of layers. The layers include a first clear coat layer made from a crosslinked polyurethane that is a reaction product of a reactive mixture including an isocyanate and a polyol containing a styrene repeat unit and a hydroxyl-containing (meth)acrylate repeat unit. The surfacing film further includes a bulk layer made from a thermoplastic polyurethane and an adhesive layer. Optionally, the surfacing film includes second clear coat layer, which can be made from a polyurethane that is at least partially crosslinked. The resulting surfacing film can display high stain resistance, high peel strength, superior scratch resistance and self-healing properties.

    Abstract: Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. When the thermoplastic polyester is selected to include aliphatic and aromatic polyesters, a spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. When the thermoplastic polyester is selected from aliphatic polyesters, a meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.

    Abstract: A display system including a lightguide and first and second reflective layers disposed on opposite sides of the lightguide is provided. The lightguide has opposing first and second major surfaces and includes a light extraction pattern for extracting light that would otherwise be confined and propagate within the lightguide primarily by total internal reflection. Light extracted by the light extraction pattern exits the lightguide through at least one of the first and second major surfaces of the lightguide. Each of the first and second reflective layers has an average specular reflectance of at least 50% in a predetermined wavelength range. The light extraction pattern may be repeatedly imaged by the first and second reflective layers to produce three-dimensional stacked images of the light extraction pattern.
