摘要： Film articles with dual-sided structures are ones in which both of the major surfaces of the film have a structured surface. The structured film articles have a first major surface and second major surface, where each surface has a plurality of spaced apart protrusions forming a repeating pattern. Each repeating pattern has a major axis, where the major axis is one of the major axes in the translational direction of the repeating pattern. The major axis of the repeating pattern on the second major surface forms an oblique angle with the major axis on the first major surface, where the angle is in the range of 10-90% of the angle of rotational symmetry of the repeating pattern. The structured film is a unitary substrate. The structured film articles are prepared by providing a flowable material composition having two major surfaces and simultaneously contacting the major surfaces with a first microstructuring tool, and a second microstructuring tool. Each microstructuring tool has a structured surface including a pattern of a plurality of depressions.

摘要： Methods of forming laminating adhesive articles include providing a multi-layer article, and a tool with a structured surface. The multi-layer articles include a substrate, an adhesive layer, and a liner or may just include an adhesive layer and a liner. The multi-layer article is placed between the structured surface of the tool and a support surface and the tool is embossed against the liner by applying pressure or a combination of pressure and heat. The embossing causes the structures on the surface of the tool to distort the liner and the adhesive layer but does not distort the substrate. The distortion in the liner is retained upon release of the applied pressure. Upon removal of the liner from the adhesive layer, the structures on the adhesive layer are unstable, but do not immediately collapse.
