Patent number: 11125406Abstract: The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.Type: GrantFiled: January 23, 2020Date of Patent: September 21, 2021Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Michael Benton Free, Martin B.

Patent number: 10723919Abstract: 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. The multi-layer article is placed between the structured surface of the tool and a support surface that is hard and the tool is embossed against the liner by applying pressure or pressure/heat. The embossing causes the tool structures to distort the liner and the adhesive layer, and causes permanent topological changes in a portion of the adhesive layer, but does not distort the substrate. The distortion in the liner is retained upon release of the applied pressure. The portions of topologically changed adhesive can form convex structures that are permanent. Upon removal of the liner from the adhesive layer, the concave structures on the adhesive layer are unstable, but the convex structures are stable.Type: GrantFiled: September 24, 2018Date of Patent: July 28, 2020Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventor: Michael Benton Free
