    摘要： Device for indicating a critical temperature, such as, for example, the freezing point of a liquid. The device comprises a sheet which is a layer having a multiplicity of micropores therein and a mixture comprising at least two liquids, said mixture incapable of wetting said sheet at a given temperature, but capable of wetting said sheet when the temperature of said mixture reaches a critical value, such as the freezing point of one of the liquids in the mixture. The micropores, or voids, in the microporous layer cause scattering of transmitted light, causing the microporous layer to appear opaque. When the voids are filled with a liquid having substantially the same index of refraction as the material of the microporous layer, the filled voids do not scatter transmitted light, thus rendering the microporous layer transmissive to visible light.A visible indicator is associated with the layer of microporous film such that at a temperature above the freezing point of the liquid composition, the visible indicator is masked by the layer of microporous film, but at a temperature at or below the freezing point of the liquid composition, the liquid wets out the layer of microporous film, thereby allowing the visible indicator to be seen through the layer of microporous film.

    摘要： The present application generally relates to multi-layer sealing films, methods of making such films, materials for inclusion in such films, retroreflective sheeting and articles including such films, and methods of making retroreflective sheeting and articles including such films. The multi-layer sealing film may include two or more layers. One exemplary embodiment of a two-layer film includes a first layer including a thermoplastic polymeric material including reaction products of alkylene and reaction products of at least one non-acidic comonomer and a second layer including one of a polyolefin, a polyester, a polymethyl methacrylate, a polyamide, a polycarbonate, an ethylene-methacrylic acid, and a polyurethane. In some embodiments, at least one of the layers of the multi-layer sealing film has an elastic modulus of at least 3.5×105 kPa and the flexural rigidity of the retroreflective article is less than about 4.0×10−8 N·m2.

    摘要： The present application is directed to a method of creating a dual appearance comprising providing a substrate. The dual appearance is further created by providing an illumination source proximate to the second major surface of the substrate. A reflective image is provided on the first major surface of the substrate opposite the illumination source. A transmitted image is provided on the second major surface of the substrate between the substrate and the illumination source. Generally, the reflective image is visible with the illumination source off and the transmitted image is visible with the illumination source on.
