Patent number: 10316226Abstract: 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.Type: GrantFiled: June 2, 2014Date of Patent: June 11, 2019Assignee: 3M Innovative Properties CompanyInventors: Michael Benton Free, Audrey A.
