Abstract: A stretchable reflective color-shifting film comprises a stretchable transparent polymer layer; a semi-transmissive metal layer; a transparent spacer layer; a reflective metal layer; an adhesive layer; and a stretchable base film layer. When the film body is stretched by 25%, the peak total reflectance stretched is at 80% of the peak total reflectance when the film body is unstretched according to the Total Reflectivity Test.

Abstract: A transfer article with a thickness of less than 3 micrometers includes a first acrylate layer that is releasable from a metal or doped semiconductor release layer at a release value of from 2 to 50 grams/inch. The article includes a functional layer overlaying the first acrylate layer. The functional layer includes at least one microfractured inorganic layer about 3 nanometers to about 200 nanometers thick, which has a plurality of toolmarks interspersed with cracks.

Abstract: The present disclosure includes a stretchable reflective film comprising a transparent polymer layer; a continuous metal layer comprising at least one of tin or indium; a non-reactive adhesive layer; and a stretchable film layer. The stretchable reflective film has at least 30% specular reflectivity when stretched by 50% of the unstretched length according to Specular Reflectivity Test Method.

Abstract: Polymer fibers are formed with concentric alternating layers of different polymer materials. The layers pairs have cross-sectional thicknesses selected for reflecting light at a selected visible wavelength. A cross-sectional dimension of the core is at least ten times an average of the selected thicknesses of the alternating layers. Some articles formed by the fibers are formed by attaching one fiber to another: the color of the fibers at the point of attachment is different from the colors of the fibers elsewhere. The fibers may be deformed to change its color properties by elongating the cross-section of the polymer fiber along a first cross-sectional axis. In some embodiments, the fibers are polarization sensitive.

Abstract: A polarizing film is made of multilayer polarizing fibers embedded within a matrix. The fibers are formed with layers of at least a first and a second polymer material. Layers of the first polymer material are disposed between layers of the second polymer material. At least one of the first and second polymer materials is birefringent. In some embodiments the thickness of the layers of at least one of the materials varies across the fiber, and may include layers are selected as quarter-wavelength thickness for light having a wavelength of more than 700 nm.

Abstract: A display system has a display panel and at least one light source for producing light to illuminate the display panel. A polarizer film may be employed between the display panel and the light source. At least one of the polarizing fibers has multiple internal birefringent interfaces between a first polymer material and a second polymer material. In some embodiments, the polarizer substantially reflects normally incident light in a first polarization state and substantially transmits normally incident light, in a second polarization state orthogonal to the first polarization state, with a haze value of at least 10%.
