Methods of forming laminating adhesive articles include providing a multi-layer article, an embossing tool with a structured surface, and a support surface tool. 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 embossing tool and the support surface tool.

The pressing causes the structures on the surface of the embossing tool to distort the liner and the adhesive layer and the support surface tool modifies the surface of 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.
