    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： Microstructured articles, such as a retroreflective articles, having a plurality of (e.g. cube-corner) microstructured elements projecting from a major surface are described. The microstructured (e.g.) cube-corner elements or interface with an adjacent layer comprises certain nitrogen-containing ingredients. The inclusion of such nitrogen-containing ingredients can improve the adhesion of the (e.g. cube-corner) elements to adjacent (e.g. olefinic) layers such as a body layer, seal film layer, or combination thereof. The flexible retroreflective articles have a light transmissive polymeric body layer having an elastic modulus of less than 7×108 pascals.
